Eurostat data shows that over 18,100 Ukrainians were granted citizenship of European Union countries in 2020, as the bloc continues to take in more Ukrainian refugees.
The EU's 27 member states naturalized just over 729,000 foreign nationals in that year, the Eurostat data said, with Spain and the Netherlands leading the way.
One in 10 of the new EU citizens came from Morocco, while Syrians represented 7% and Albanians 6%. The majority of new citizens originated from outside the bloc or were stateless, Eurostat said.
Ukrainians made up 3% of new citizens during the year, largely in its western neighbor Poland, which naturalized close to 3,900 – the most of any EU country and more than double its figure in 2014, when Russia annexed Ukraine's Crimean peninsula.
Germany, Italy, Spain and Portugal each naturalized more than 2,000 Ukrainians in 2020.
Women or girls made up nearly two-thirds of the new EU citizens from Ukraine, the data showed.
More than 3 million Ukrainians, mostly women and children, have entered the EU, especially Poland, over the past three weeks, fleeing Russia's invasion of their country. The EU has agreed to ease their access to jobs, schools, health care and welfare services. It is unclear how long they will stay or how many of them might eventually seek naturalization.
Eurostat found that EU states had in 2020 naturalized around 16,000 British people, following the United Kingdom's exit from the bloc, 15,000 Russians and 3,500 Belarusians.
Nearly three-quarters of the over 9,500 Afghans who were granted EU citizenship were naturalized in Sweden, Germany or Belgium.
