Demographics

The 20 most international municipalities on Spain's Mediterranean coast

Published August 2026 · MyCasa Spain Research

Key findings

  1. Rojales (Alicante) is the most international municipality on the Spanish Mediterranean coast, with 67.8% of its 16,989 registered residents holding a foreign nationality as of 1 January 2025 (INE, Censo Anual de Población).
  2. Fifteen municipalities in Alicante province alone have a foreign-national majority — more than every other Mediterranean province combined; 28 of the Comunitat Valenciana's 30 most international municipalities are in Alicante.
  3. Calp is the only Spanish municipality above 25,000 inhabitants where foreigners outnumber Spaniards, at 53.1% foreign nationality across a population of 26,637, and it registers residents of 99 different nationalities (El Economista).
  4. Benahavís (Málaga) is the most international municipality outside Alicante province, at 61.8% foreign nationality — the highest figure on the entire Costa del Sol and the wealthiest profile in the top 20.
  5. The British are no longer the largest foreign community in Torrevieja, Spain's best-known "British" town: Ukrainians (9,512), Russians (5,926) and Colombians (5,141) all now outnumber UK nationals (4,708) on the municipal register (Ayuntamiento de Torrevieja).
  6. l'Alfàs del Pi (Alicante) hosts 2,626 registered Norwegians — a community its own councillor describes as the largest Norwegian settlement in the world by both age and size, with the real figure locally estimated at around 8,000 once unregistered residents are counted.
  7. Calp's foreign population has an effective diversity of roughly 16 nationalities on a Herfindahl-based measure, against a top-four concentration of 39.1% — versus 45.6% in Torrevieja, which has more nationalities (123) but a far more concentrated mix.
  8. Teulada-Moraira has approximately 13,000 dwellings for 12,857 registered residents, the clearest single illustration that the padrón systematically under-counts second-home owners on this coast.
  9. Three provinces — Madrid, Barcelona and Alicante — concentrate 40% of all foreign nationals resident in Spain, and five provinces exceed a 20% foreign-national share: Alicante, Almería, Girona, Illes Balears and Lleida (INE, 1 January 2025).
  10. Spain's foreign-born population passed 10 million for the first time, reaching 10,154,722 at 1 April 2026, out of a total population of 49,570,725 at 1 January 2026 (INE, Estadística Continua de Población).

Executive summary

We ranked every municipality on Spain's Mediterranean arc — from Girona down to Málaga, plus the Balearic Islands — by the share of registered residents holding a foreign nationality, using the INE Censo Anual de Población with a reference date of 1 January 2025. To avoid the statistical noise that afflicts very small villages, we applied a floor of 5,000 inhabitants. The result is a ranking in which the top of the table is almost entirely a Costa Blanca phenomenon: Alicante province supplies twelve of the top twenty, with secondary clusters in western Málaga, the Almería Levante, the Costa Brava and Mallorca.

The headline number is Rojales, where 67.8% of residents are foreign nationals. But the more useful finding is that "most international" is not one question. We built three overlapping rankings, and each produces a different winner. Ranked by total foreign share, the leaders are British and Northern European retirement towns in the Vega Baja and Marina Alta. Ranked by EU nationals only — a definition Brexit rewrote overnight, since UK nationals are now third-country nationals — the picture shifts decisively towards German, Dutch, Belgian and Romanian towns. Ranked by the balance of the nationality mix rather than its size, the winner is Calp, where the largest single foreign nationality accounts for barely 6% of the total population and 99 nationalities coexist in an unusually flat distribution.

The third finding is methodological, and it is the one that matters most to anyone who actually lives on this coast: the register understates reality. The padrón counts people who have chosen to register with their town hall. It misses second-home owners who never register, and it retains people who left without deregistering. Calp's own council states that hundreds of resident foreigners are absent from its figures. Teulada-Moraira has more dwellings than registered residents. In l'Alfàs del Pi, the local estimate of the Norwegian community is roughly three times the registered count. Every percentage in this report should therefore be read as a floor, not a ceiling — particularly in the Marina Alta and on the western Costa del Sol, where second-home ownership is heaviest.

We also flag two data limitations openly rather than papering over them. INE's public municipal tables do not cleanly separate EU from non-EU nationality at municipal level for the 1 January 2025 vintage; that split is published by province. And a fully auditable diversity index for every municipality requires the complete country-of-nationality vector per town, which sits in INE series e245 and the regional statistics offices rather than in the headline tables. Where we could compute an index from published counts, we show the arithmetic. Where we could not, we say so and decline to publish a number.

Geographic scope

The Spanish Mediterranean arc: the provinces of Girona, Barcelona, Tarragona, Castellón, Valencia, Alicante, Murcia, Almería, Granada and Málaga, plus the Balearic Islands. The Canary Islands are excluded — Adeje, Arona and Mogán would rank highly on any national list, but they are Atlantic and outside the scope of this report.

Granularity and inclusion threshold

Municipality level. Only municipalities with 5,000 or more registered inhabitants are eligible for the ranking. This threshold is a deliberate editorial choice: below it, a single urbanisation of a few hundred houses can push a village above 65% and the ranking stops measuring anything meaningful. Several well-known cases fall below the line and are excluded from the tables, though they are noted here for completeness: Llíber (approx. 1,200 inhabitants, and among the highest foreign shares in Spain), el Poble Nou de Benitatxell (4,959), Algorfa (3,719), Benijófar (3,521), els Poblets (2,720), Alcalalí (1,377), Arboleas (4,296), Hondón de los Frailes (1,296) and Daya Vieja.

The metric: nationality, not birthplace

Rankings A and B measure foreign nationality (extranjeros) — people registered with a passport other than a Spanish one. They do not measure foreign birthplace (nacidos en el extranjero), which is a larger figure because naturalised residents and dual nationals count as Spanish under the nationality definition.

This distinction is the single most common source of contradictory headlines about this coast, and it matters in two directions. It deflates apparent internationality in municipalities with large Latin American communities, where naturalisation rates are high. And it explains why the widely quoted regional figure for the Balearic Islands — 28.7%, the highest of any Spanish region — is a foreign-born figure and cannot be compared like-for-like with the municipal percentages in Ranking A.

Note on source divergence. A widely syndicated aggregator table published in May 2026 reports materially higher figures for the same municipalities (San Fulgencio 77.6%, Rojales 72.4%, Mijas 49.7%, Benalmádena 53.6%) and applies a 1,000-inhabitant threshold. Those figures do not reconcile with the INE Censo Continuo values reproduced by the regional statistics offices and the regional press, and appear either to use a foreign-born basis or to mix data vintages. This report uses the INE Censo Continuo basis throughout. Readers comparing our table with that one will find the discrepancy is systematic, not random.

The diversity index

Ranking C uses the Herfindahl–Hirschman Index (HHI) applied to the nationality composition of a municipality. For each nationality i present, let sᵢ be its share of the relevant population. Then:

HHI = Σ (sᵢ)²

A low HHI means no group dominates; a high HHI means the foreign population is concentrated in one or two nationalities. We report two transforms alongside it, because both are more intuitive for a general reader:

  • Diversity index = 1 − HHI (0 = a single group; approaching 1 = perfectly mixed)
  • Effective number of nationalities = 1 / HHI

We also report the CR4 — the combined share of the four largest foreign nationalities — because it can be computed from published counts even where the full nationality vector is unavailable, and it is directly comparable between municipalities.

Limitations

  1. Under-registration. The padrón records people who register. Foreign second-home owners frequently do not, and EU residents who fail to renew their inscription drop out. All figures are therefore floors.
  2. Over-registration. The opposite error also occurs: residents who leave Spain without deregistering remain on the roll, inflating counts in some municipalities.
  3. Seasonality. The register is a single-date snapshot and captures none of the winter–summer swing. Calvià's population rises from 53,793 to roughly 269,000 in peak season; Benidorm's from 77,327 to roughly 507,000; Lloret de Mar's from about 43,000 to about 215,000 (idealista/news).
  4. The EU/non-EU municipal split is not publicly available. INE publishes the comunitarios / no comunitarios breakdown at provincial, not municipal, level for this vintage. Ranking B is therefore presented qualitatively, with the composition evidence we could source, and without invented percentages.
  5. Complete diversity indices require microdata. We computed a full index only where the underlying nationality counts are published. For the remainder we report the verified nationality count and, where possible, CR4 — and flag the rest as pending.
  6. Two population bases coexist. INE's Censo Continuo and municipal padrón publications can differ for the same town and date. Torrevieja is the clearest case: 47.6% on the INE Censo basis, 52.09% on the town hall's own padrón. We cite both rather than choosing silently.

Just outside the top 20

Several larger and better-known towns sit immediately below the cut, and are more useful than the leaders for readers who want a substantial expatriate population combined with a full-service town:

Municipality Province % foreign nationality Population
Fuengirola Málaga 38.4% 85,646
Guardamar del Segura Alicante 37.8% 18,063
Oropesa del Mar Castellón 37.3% 11,594
Orihuela Alicante 36.1% 83,348
Calvià Illes Balears 33.8% 53,793

El Ejido Almería 31.5% 89,462
Marbella Málaga 30.3% 159,054
Roquetas de Mar Almería 30.1% 108,348

Two different phenomena in one table

The ranking conflates two entirely distinct migrations, and any journalist using it should separate them. Níjar (47.4%), El Ejido (31.5%), Vícar (32.9%) and Roquetas de Mar (30.1%) are agricultural economies in Almería whose foreign population is predominantly Moroccan and West African labour attached to intensive greenhouse horticulture. Rojales, San Fulgencio, Teulada, Benahavís and Mojácar are residential-tourism economies whose foreign population is predominantly Northern European and retirement-driven. Both are genuinely "international". They have almost nothing else in common — different age profiles, different housing stock, different labour-market position, different relationship with the town hall.

Profiles: the top 10

1. Rojales (Alicante) — 67.8%, 16,989 residents. Set in the Vega Baja del Segura, roughly six kilometres inland but functionally coastal through Ciudad Quesada, a vast urbanisation developed from the 1970s onwards on the hills above the river. British nationals alone account for over 40% of the total population. The model is retirement-led and long-established, with a substantial second-home component alongside permanent residents. Historic reporting put the foreign share as high as 76.8% in 2012, making Rojales one of the few municipalities where the ratio has moderated rather than climbed.

2. San Fulgencio (Alicante) — 66.9%, 9,587 residents. The neighbouring case, and structurally similar: the La Marina urbanisation dwarfs the historic village. British and German retirees dominate. San Fulgencio is the municipality most often cited in Spanish coverage of foreign political participation, having run election campaigns in English and Norwegian, and it has repeatedly elected councillors from the foreign-resident community.

3. Benahavís (Málaga) — 61.8%, 9,256 residents. The outlier of the top ten in every respect. Benahavís sits inland between Marbella and Estepona and is the wealthiest municipality on the list — a landscape of golf resorts, gated villa developments and La Zagaleta. Its foreign population is British and affluent Northern European, skews younger than the Alicante retirement towns, and is far more likely to be economically active. Its foreign share has risen sharply: the 2021 census recorded 48.4%.

4. Teulada–Moraira (Alicante) — 56.4%, 12,857 residents. Marina Alta, with the coastal core at Moraira and the historic town of Teulada inland. The mix is German, British, Dutch and Belgian, and the profile is the most second-home-weighted in the top ten: the municipality has approximately 13,000 dwellings for 12,857 registered residents. Foreign-resident electoral lists have contested local elections here since the 1990s. This is the municipality where the gap between registered and actual foreign presence is likely widest.

5. San Miguel de Salinas (Alicante) — 56.1%, 7,110 residents. Vega Baja, inland-adjacent, overlooking the Torrevieja salt lagoons. British and German retirement urbanisations built out from the 1980s. A smaller, quieter variant of the Rojales model, with a heavier permanent-resident share and less holiday-letting churn.

6. Calp (Alicante) — 53.1%, 26,637 residents. The most important case in the whole ranking. Calp is the only Spanish municipality above 25,000 inhabitants where foreign nationals outnumber Spaniards, and its 99 registered nationalities are distributed unusually evenly — the largest single foreign nationality is Colombian, at only about 6% of the total population. Its municipal padrón of February 2026 records 28,092 residents and a 54.9% foreign-born share. The town hall states that hundreds of resident foreigners are missing from the register because they never renewed their inscription.

7. l'Alfàs del Pi (Alicante) — 49.8%, 20,425 residents. Marina Baixa, coastal at l'Albir. Home to 2,626 registered Norwegians and, on the local estimate, roughly 8,000 in reality — a community with its own church, school and care provision, and which the municipality's own councillor for resident communities describes as the largest Norwegian settlement anywhere in the world, both by longevity and by size. Dutch and Romanian communities follow. Because Norway is EEA rather than EU, l'Alfàs behaves differently in Ranking A than in Ranking B.

8. Finestrat (Alicante) — 49.5%, 9,389 residents. Marina Baixa, immediately inland of Benidorm, with the coastal strip at Cala de Finestrat. British and Northern European residential development, much of it recent, attached to the Benidorm service economy. Younger and more economically mixed than the Vega Baja towns.

9. Mojácar (Almería) — 49.1%, 7,455 residents. The Levante Almeriense white village and the anchor of the province's British cluster, which extends inland through the Almanzora valley. Mojácar's foreign community began as a holiday and artistic colony in the 1960s and converted progressively to permanent residence. It is the only Almería municipality in the top ten whose internationality is residential rather than agricultural.

10. Torrevieja (Alicante) — 47.6% on the INE Censo basis, 95,760 residents; 52.09% and 106,350 residents on the town hall's own padrón at 1 January 2025. The largest genuinely international town on the coast and, for a UK audience, the most counter-intuitive entry: Torrevieja is widely described as a British town and is no longer one. Ukrainians (9,512), Russians (5,926) and Colombians (5,141) each outnumber UK nationals (4,708). One hundred and twenty-three nationalities are registered. The summer population roughly triples.

Ranking B — the EU-only picture after Brexit

This is the ranking Brexit rewrote, and the one we cannot publish as a numbered table without inventing data.

The data gap, stated plainly

INE publishes the comunitarios / no comunitarios split at provincial level for the 1 January 2025 vintage. It does not publish a clean EU/non-EU breakdown for every municipality in its headline tables. Building Ranking B rigorously requires the municipal country-of-nationality vector — INE series e245 — or equivalent queries to IBESTAT, PEGV, Idescat and IECA. We have not obtained that vector for the full municipal set, and we are not going to estimate one. No EU-only percentages appear in this report.

What can be said with confidence

British nationals are now third-country nationals. That single reclassification removes the largest foreign community from the EU column in Rojales, San Fulgencio, Pilar de la Horadada, Los Montesinos, Mojácar, Orihuela and the Almanzora valley — precisely the municipalities that lead Ranking A. Norwegians are EEA, not EU, which similarly reclassifies the largest community in l'Alfàs del Pi.

The municipalities that rise on an EU-only measure are therefore those where the dominant foreign communities are German, Dutch, Belgian, French, Italian, Romanian, Bulgarian or Polish:

  • Teulada–Moraira — a German, Dutch and Belgian core that survives the reclassification almost intact.
  • Calp — Belgium (1,414), Romania (1,229), Germany (1,053) and the Netherlands (745) are all EU and collectively large; Calp's EU population is bigger than its British one.
  • Torrox — one of the largest German communities on the Costa del Sol, and the only Málaga municipality in Ranking A whose profile is German-led rather than British-led.
  • Dénia, Benissa and Xàbia — the Marina Alta's German, Dutch and Belgian weight.
  • Castelló d'Empúries and Roses — Costa Brava, with French, German, Dutch and Italian communities.
  • Santa Eulària des Riu and Sant Josep de sa Talaia — Ibiza's Italian, German and French residents.

The national backdrop

At 1 January 2024 there were 272,402 UK nationals registered in Spain, with Andalucía (84,503) and the Comunidad Valenciana (81,455) holding the largest shares. The direction of travel is downward: UK registrations fell by 5,940 nationally in 2024, and by roughly 3,700 in Alicante province alone. Meanwhile the fastest-growing bloc in Alicante is the Americas, at 98,849 residents and 21.3% of the province's foreign population, with Ukraine the fourth-largest single nationality. Europe still accounts for 57.8% of Alicante's foreign residents, but the composition inside that share is changing.

Ranking C — the nationality diversity index

Having many nationalities is not the same as being diverse. A town can register 120 nationalities and still be overwhelmingly one community. Ranking C measures balance.

The winner, with the arithmetic shown

Calp is the strongest candidate for the most nationality-diverse municipality on the Spanish Mediterranean coast. Its municipal padrón of February 2026 records 28,092 residents, a 54.9% foreign-born share (15,422 people) and 99 nationalities, with the ten largest foreign communities as follows: Colombia 1,706; United Kingdom 1,464; Ukraine 1,447; Belgium 1,414; Romania 1,229; Russia 1,123; Germany 1,053; Morocco 1,015; Netherlands 745; Senegal 320.

Note — calculation. The ten largest foreign communities total 11,516 people, leaving approximately 3,906 residents distributed across the remaining 89 nationalities. Computing the HHI within the foreign population (base 15,422), the shares are Colombia 11.06%, UK 9.49%, Ukraine 9.38%, Belgium 9.17%, Romania 7.97%, Russia 7.28%, Germany 6.83%, Morocco 6.58%, Netherlands 4.83%, Senegal 2.07%, with 25.33% in the tail. Squaring and summing gives HHI ≈ 0.0619 for the named ten; assuming the tail is evenly distributed across 89 nationalities adds approximately 0.0007, for HHI ≈ 0.063. That yields a diversity index (1 − HHI) of approximately 0.937 and an effective number of nationalities of approximately 16. The even-tail assumption is a simplification and will slightly overstate diversity; the true figure is marginally lower. Note also that this calculation uses the foreign-born base of 54.9% from the municipal padrón (February 2026), not the 53.1% foreign-nationality figure from the INE Censo (1 January 2025).

Comparative concentration where the data allows

The CR4 — the share of the foreign population held by its four largest nationalities — can be computed wherever the top four counts are published, and it travels well between municipalities:

Municipality Nationalities registered Four largest foreign communities CR4 Interpretation
Calp 99 Colombia, UK, Ukraine, Belgium 39.1% Exceptionally balanced
Torrevieja 123 Ukraine, Russia, Colombia, UK 45.6% More nationalities, more concentrated

Note — calculation. Calp: the four largest foreign communities total 6,031 of 15,422 foreign residents = 39.1%. Torrevieja: 9,512 + 5,926 + 5,141 + 4,708 = 25,287 of approximately 55,398 foreign residents (52.09% of 106,350 on the municipal padrón) = 45.6%.

This is the finding worth a headline in itself: Torrevieja has 24 more nationalities than Calp and is measurably less diverse, because its foreign population is concentrated in a Ukrainian–Russian–Colombian core.

Candidates pending full computation

The following municipalities are the strongest remaining candidates on the number of registered nationalities. We publish the nationality counts, which are verified, and withhold index values, which are not:

Municipality Province Nationalities registered Status

What the register does not capture

Second-home owners

The most consequential blind spot. Registration on the padrón is a legal obligation for anyone habitually resident in a Spanish municipality, but it is not enforced against people who spend three or four months a year in their property, and many owners actively avoid it out of confusion about tax residency — a confusion worth correcting, since the padrón is a municipal population register, not a tax register, and inscription does not by itself make anyone a Spanish tax resident.

The evidence for the gap is direct rather than inferred. Calp's council states that hundreds of resident foreigners are absent from its figures because they never renewed their inscription. Teulada-Moraira has approximately 13,000 dwellings for 12,857 registered residents. l'Alfàs del Pi registers 2,626 Norwegians against a local estimate of roughly 8,000.

For readers, the practical implication is that the real foreign share in the Marina Alta and on the western Costa del Sol is higher — probably materially higher — than Ranking A shows. For journalists, the implication is that every figure in this report is a lower bound.

Deregistration failure

The error runs both ways. Residents who leave Spain without notifying the town hall stay on the roll until the periodic renewal cycle catches them. Non-EU nationals must renew every two years, but EU and EEA nationals are subject to a five-year confirmation cycle, so departures from the British, German, Dutch and Norwegian communities can persist on the register for years. This particularly affects municipalities that saw large post-Brexit and post-pandemic departures.

Seasonality

None of the figures in this report describe summer. The peak-to-baseline multipliers on this coast are extreme: Benidorm rises from 77,327 registered residents to approximately 507,000 at peak, a 555% increase; Calvià from 53,793 to approximately 269,000; Lloret de Mar from approximately 43,000 to approximately 215,000. A municipality's "international" character in August bears little resemblance to its character in February, and the services available to residents — including trades and emergency repairs — vary accordingly.

Regional deep-dives

Costa Blanca (Alicante province)

Alicante is the centre of gravity of this entire report. It supplies twelve of the top twenty, and fifteen of its municipalities have an outright foreign-national majority. Twenty-eight of the Comunitat Valenciana's thirty most international municipalities lie within the province. At provincial level, 23.3% of Alicante's registered residents held a foreign nationality at 1 January 2024.

Three distinct sub-regions produce this concentration.

The Vega Baja del Segura — Rojales, San Fulgencio, San Miguel de Salinas, Torrevieja, Pilar de la Horadada, Los Montesinos, Guardamar, Orihuela Costa — is the oldest and largest cluster, built on high-density, low-cost urbanisations from the 1970s onwards, historically British-dominated and retirement-led. It is also the sub-region changing fastest: the Ukrainian, Russian and Colombian communities that now lead Torrevieja are reshaping the demographic profile of the whole comarca.

The Marina Alta — Teulada-Moraira, Calp, Xàbia, Benissa, Dénia, and the sub-5,000 villages of Llíber, Benitatxell and Alcalalí — is lower-density, higher-value, and the most German-, Dutch- and Belgian-weighted stretch of the entire Spanish coast. It is also the most second-home-weighted, and therefore the sub-region where the register understates reality most severely.

The Marina Baixa — l'Alfàs del Pi, Finestrat, Altea, La Nucía, Polop — combines the Nordic communities around l'Albir with the service economy of Benidorm. It is younger and more economically active than the Vega Baja.

Costa del Sol (Málaga province)

Málaga province registers 18.5% foreign nationality overall, but the distribution is extremely uneven. Benahavís (61.8%) is the provincial and coastal outlier — a wealth-driven case with no real parallel in Alicante. Manilva (39.0%) and Torrox (38.9%) follow, and the western corridor from Estepona to Manilva is where growth has been fastest.

The large, well-known towns sit lower than their reputation implies: Fuengirola 38.4%, Mijas 32.0%, Marbella 30.3%, Benalmádena in the mid-20s. What they lack in percentage they make up in absolute numbers and in variety — Fuengirola registers over 130 nationalities, Estepona approximately 120, Mijas over 100, Manilva 93. The Costa del Sol's internationality is broad rather than concentrated: no single nationality dominates the way the British dominate the Vega Baja or the Germans the Marina Alta, though the British remain the largest single community in Estepona and across most of the western corridor.

Torrox deserves separate mention as the clearest German-led municipality on the Andalusian coast, and the one Málaga entry that would climb rather than fall on an EU-only ranking.

Balearic Islands

The Balearics hold the highest foreign-born share of any Spanish region at 28.7% (1 January 2025), ahead of Catalonia (25.1%) and Madrid (24.9%), and 21.2% on a foreign-nationality basis. But no Balearic municipality enters the top twenty of Ranking A, because the islands' internationality is spread rather than concentrated.

The leaders are Calvià (33.8%), Alcúdia (28.7%), Andratx (28.6%), Santanyí (28.3%), Capdepera (27.6%) and Pollença (25.5%) — a band of six municipalities in a narrow range, which is itself the story. Mallorca as a whole records approximately 21.25% foreign nationality.

The nationality mix confounds the German-island cliché. The largest foreign communities across the Balearics are Colombia (approx. 41,900), Argentina (approx. 38,485) and Morocco (approx. 34,243), ahead of Germany (approx. 21,723) and the United Kingdom (approx. 18,374). Germans are highly visible and heavily concentrated in specific municipalities — Andratx, Calvià, Santanyí, Pollença — but they are not the largest foreign nationality on the islands, and any report claiming otherwise is describing a subset.

Calvià is also the most seasonally volatile municipality in this report, moving from 53,793 registered residents to roughly 269,000 at peak.

Costa Brava and Costa Daurada (Girona, Barcelona, Tarragona)

Catalonia contributes two entries: Castelló d'Empúries (45.5%) and Lloret de Mar (38.5%). They are different animals. Castelló d'Empúries owes its position to Empuriabrava, the vast canal-side marina development built from the 1960s, whose German, French, Dutch and Italian second-home owners give it a genuinely EU-weighted profile — one of the few municipalities in this report that would rank comparably on Rankings A and B. Lloret de Mar's foreign population is a broader mix of European, Latin American and Maghrebi residents attached to a mass-tourism economy, and its 400% summer multiplier is among the largest on the coast. Girona province registers 21.6% foreign nationality overall; Tarragona 18.4%.

Almería and Murcia

Almería is the province where the two migrations described earlier collide most visibly. At 22.7% foreign nationality it ranks second on the Mediterranean arc, but its entries split cleanly: Mojácar (49.1%) is a British residential colony, while Níjar (47.4%), Vícar (32.9%), El Ejido (31.5%) and Roquetas de Mar (30.1%) are agricultural economies whose foreign populations are predominantly Moroccan and West African. Provincially, the largest nationalities are Morocco (approximately 82,000), Romania (approximately 24,000) and the United Kingdom (approximately 15,000). The inland Almanzora valley — Arboleas at 67.0%, Albox, Turre — contains some of the highest British shares in Spain, but most of those municipalities fall below our 5,000-inhabitant threshold.

Murcia, at 15.4% foreign nationality, produces no top-twenty entry. Its foreign residents are concentrated in the Mar Menor developments and in agricultural municipalities inland, and the province's overall profile is diluted by a large Spanish-national interior.

Castellón and Valencia

Castellón registers 17.7% and Valencia 14.6%. Castellón's one strong entry is Oropesa del Mar (37.3%), a Marina d'Or-driven residential-tourism case that closely resembles the Alicante model in miniature. Elsewhere, Peñíscola, Alcossebre and Benicàssim show meaningful foreign populations without approaching the top twenty. The Valencia coast — Gandia, Oliva, Cullera — has a substantial Northern European presence, particularly Dutch and Belgian in Oliva, but no municipality above the threshold enters the ranking.

What this means for foreign residents

A high foreign percentage does not mean services in your language. This is the most common and most expensive misreading of the numbers in this report. Rojales is 67.8% foreign, and its plumbers, electricians and locksmiths are overwhelmingly Spanish businesses operating in Spanish. What a high share does reliably deliver is an intermediary layer — administrative offices, gestorías, estate agents and neighbours who have solved the same problem before. That layer is thickest in the Vega Baja and the Marina Alta and thinnest in municipalities where the foreign population is agricultural rather than residential.

Percentage and absolute numbers pull in opposite directions. Los Montesinos is 39.3% foreign, but that is roughly 2,200 people. Marbella is 30.3% foreign, which is roughly 48,000. If your priority is a dense support network, a large well-connected community and a deep local market for services, the larger towns just outside the top twenty — Fuengirola, Orihuela, Mijas, Marbella, Roquetas — serve better than the small high-percentage villages, in most cases decisively.

Check which nationality actually dominates, not just the headline share. Two municipalities at 50% foreign can feel entirely different. Torrox and Teulada are German-weighted; Rojales and San Fulgencio are British-weighted; l'Alfàs del Pi is Norwegian-weighted; Torrevieja is now Eastern European and Latin American. The community you will actually meet — and the language the informal help network operates in — follows the mix, not the total.

Register on the padrón. It is a municipal population register, not a tax register, and inscription does not by itself determine tax residency. It does determine your access to municipal services, your entry onto the healthcare and school allocation systems, and your right to vote in local elections if you are an EU or EEA national. It also determines whether your town hall knows you exist when it plans services — which, given the under-count documented in this report, is not a trivial consideration in Calp, Teulada or l'Alfàs.

Plan for the seasonal swing. In municipalities with multipliers like Benidorm's 555% or Calvià's 400%, everything you might need in August — a plumber, an electrician, an appointment, a parking space — is competing with a population several times the winter baseline. Repairs that can be scheduled are cheaper and faster outside the peak. Anything you can arrange in October rather than July, arrange in October.

Treat the published percentage as a floor. If you are assessing a Marina Alta town by its foreign share, add a mental margin for the second-home owners who never registered. The community around you will usually be larger and more visible than the register suggests — most obviously in Teulada-Moraira, Calp, Benitatxell and Llíber.

Frequently asked questions

Which is the most international municipality in Spain? On the Mediterranean coast, Rojales in Alicante province, where 67.8% of registered residents held a foreign nationality at 1 January 2025. Nationally, some Canary Islands municipalities rank higher, and several villages below 5,000 inhabitants exceed 67% but are excluded here as statistically noisy. Rojales is the highest among coastal Mediterranean municipalities of meaningful size.

Why does this report say Mijas is 32% when I have seen 49.7%? Because the two figures measure different things or use different vintages. This report uses foreign nationality from the INE Censo Anual de Población at 1 January 2025. Higher figures circulating in 2026 aggregator tables appear to use foreign birthplace or mix data vintages, and do not reconcile with the regional statistics offices. We flag the discrepancy openly in our methodology.

Is Torrevieja still a British town? Not by the numbers. At 1 January 2025 Torrevieja registered 9,512 Ukrainians, 5,926 Russians and 5,141 Colombians against 4,708 UK nationals. The British community remains large, visible and long-established, and dominates specific urbanisations, but it is now the fourth-largest foreign nationality in the municipality across 123 nationalities in total.

Which town has the largest German community? On the Mediterranean coast, Torrox in Málaga province and the Marina Alta municipalities of Teulada-Moraira, Calp, Dénia and Benissa have the highest German concentrations. Across the Balearics, Germany accounts for approximately 21,723 residents, concentrated in Andratx, Calvià, Santanyí and Pollença — though Colombians, Argentinians and Moroccans each outnumber Germans island-wide.

Do these percentages include second-home owners? No. The padrón counts people who register with their town hall, and many foreign second-home owners never do. Calp's council states hundreds of its resident foreigners are missing from the register; Teulada-Moraira has roughly 13,000 dwellings for 12,857 registered residents. Every percentage in this report should be read as a floor.

Which municipality has the most nationalities? Torrevieja, with 123 registered nationalities, followed by Fuengirola with over 130 by some counts, Orihuela with 121 and Benalmádena with over 120. But nationality count is not diversity: Calp registers only 99 nationalities yet is measurably more balanced, with a top-four concentration of 39.1% against Torrevieja's 45.6%.

Are the British still counted as EU residents? No. Since Brexit, UK nationals are third-country nationals in Spanish statistics and in law, which is why an EU-only ranking looks very different from the total-foreigner ranking. Norwegians are EEA rather than EU, which similarly affects l'Alfàs del Pi. UK registrations in Spain fell by 5,940 during 2024.

Do I have to register on the padrón if I only spend a few months a year in Spain? Registration is a legal obligation for habitual residents, and there is no automatic penalty regime for occasional visitors. It is a municipal population register, not a tax register, and inscription does not by itself establish tax residency. Rules and enforcement vary by municipality and change over time — confirm your position with a gestor or lawyer.

Why are Almería's agricultural towns in the same ranking as Costa Blanca retirement towns? Because the metric counts all foreign nationals. Níjar (47.4%), El Ejido (31.5%) and Roquetas de Mar (30.1%) have large Moroccan and West African populations attached to intensive horticulture, while Rojales and Teulada have Northern European retirement populations. Both are accurately "international". The ranking should always be read with that distinction in mind.
