Poland was fined by the EU for refusing migrant quotas. It accepted none. Then it welcomed 2 million Ukrainian refugees with no camps and 69% employment.
When Russia invaded Ukraine in February 2022, Poland opened its borders. Families opened their homes. No refugee camps were built.
Poland's refugee intake surged from near-zero to one of the highest in Europe within months of the 2022 invasion.
Poland's refugee population was minimal before 2022. The spike is entirely driven by the Ukrainian crisis — a voluntary, targeted response.
Poland was fined millions of euros by the EU for refusing to accept migrants under the 2015 quota system. It accepted none. Instead, it invested in border infrastructure.
PLN 10 billion investment to fortify 700km of the eastern border (Polish-Belarusian and Kaliningrad). Steel barriers, 3,000 surveillance cameras, motion sensors, and AI-based detection systems — achieving a 96% reduction in illegal crossing attempts.
Poland has one of the lowest immigrant populations in the EU, yet one of the highest refugee-to-population ratios after 2022.
Germany: 162,000 found illegally present. Italy: 109,000. France: 109,000. Spain: 85,000. Poland: 5,600. The UK recorded 41,000 Channel crossings in 2025 alone.
Watch how foreign-born population shares evolved across countries from 1990 to 2024. Poland remained at ~2% while Western Europe doubled or tripled.
World Bank data (SM.POP.TOTL.ZS) with interpolation between census data points for animation. Poland's migrant stock barely moved from 2.2% (2000) to 4.5% (2024).
Foreign-born population by city. Warsaw at 7% vs Amsterdam 38%, London 41%. Pie charts show the split between nationals, EU citizens, and non-EU residents.
Pie charts show citizenship (who holds which passport). Foreign-born % (country of birth) shown separately on hover.
Poland has the lowest Muslim population share in Europe (<0.1%) — estimated 25,000–50,000 in a nation of 38 million, with only 3 purpose-built mosques in the entire country.
France leads at 10%, followed by Sweden (8.1%) and Belgium (7.6%). Poland remains below 0.1%. Darker shading indicates higher Muslim population share.

Bars: Pew 2010/2016 baseline + AI-scraped Wikipedia estimates (2025). After 2025 frozen at last known value. Quality varies — most countries lack census religion data.
Dashed markers: Pew Research 2017 projection for selected scenario — interpolated from 2016 to 2050. Always shown after 2016 as reference. Model not updated since 2017.
Census markers: Independently scraped from country-specific sources — UK ONS Census 2021, German BAMF studies, Austrian Statistik Austria, French INED/IFOP surveys, Dutch CBS, Spanish UCIDE. Only UK, Austria, and Ireland have actual census religion questions.
The Pew Research Center 2017 study is the only multi-country, multi-scenario projection of Muslim populations in Europe. It is cited by the BBC, The Economist, Guardian, European Commission, and every major publication covering this topic. No alternative model of comparable scope exists.
However, the model has not been updated since 2017 and uses a 2016 baseline. Actual data from national censuses and statistics offices (UK ONS 2021 Census, German BAMF, Austrian Census 2021, CBS Netherlands, UCIDE Spain) shows reality in 2020-2025 tracking at or below the zero migration scenario for most countries. This suggests Pew overestimated Muslim fertility convergence timelines and/or underestimated methodological differences between census approaches.
Most European censuses do not ask about religion. France legally prohibits it. Germany does not include it. Only the UK (6.5%, 2021 Census), Austria (8.3%, 2021 Register Census), and Ireland (1.8%, 2022 Census) have hard census data. All other figures are estimates from surveys, immigration records, and birth data.
After EU accession in 2004, ~2.3 million Poles moved abroad — mainly to the UK, Germany, and Ireland. Since 2019, return migration exceeds departures. The UK Polish population dropped from 818K to 600K post-Brexit.
