Migration to EU countries caused their populations to grow in 2023. After declines in 2020 and 2021 due to the coronavirus pandemic, it rose for the second year in a row last year – to 449.2 million from 447.6 million in 2022. According to data published by the EU statistics office Eurostat on Thursday, migration was the decisive factor, as the number of deaths exceeded the number of births in the community of 27 countries from Portugal to Cyprus.
