Population change - 1st quarter of 2025

Between 1 January and 31 March this year, the population of the Czech Republic fell from 10,909,500 to 10,876,875. "In the first three months of this year, the Czech Republic lost 32.6 thousand inhabitants, which is similar to the first quarter of 2024. The population fell by 12.6 thousand due to an excess of deaths over births, and by a further 20.1 thousand due to negative net international migration," explains Michaela Němečková from the Demographic Statistics Unit of the Czech Statistical Office. The weight of natural decline increased slightly this year compared to last year.

A total of 18.1 thousand children were born alive, which is 2.9 thousand, or by 14%, fewer than in the previous year. This is the fourth year in a row that the birth rate has been declining. Of these, 8.4 thousand were first-born, 7.0 thousand were second-born, and 2.7 thousand were third-born or higher-order. The women who gave birth most frequently were those born between 1993 and 1996. 48.1% of children were born outside of marriage.

During the first three months of 2025, 30.6 thousand Czech residents died, which is almost 1.0 thousand (or 3%) more than in the same period of 2024. There were more deaths year-on-year in all five-year age groups over 70. The highest number of deaths was among those aged 80–84 (5.3 thousand) and 75–79 (5.2 thousand).

In the first quarter of this year, 3.0 thousand couples entered into marriage, which is almost 0.4 thousand, or 14%, fewer than a year ago. This is the third year in a row that the number of marriages has been decreasing. Most of the grooms were aged 30–34, and most of the brides were aged 25–29. A total of 4.9 thousand marriages ended in divorce, which is 0.1 thousand (2%) fewer than the year before. The most common divorces were those involving marriages that had lasted five, six or two years, corresponding to the higher number of marriages concluded in 2019, 2018 and 2022 respectively. Three-fifths of divorced couples had at least one minor child together.

In the first quarter of 2025, the net international migration resulted in a balance of −20.1 thousand people. As in the first quarter of 2024, this decline was caused by a high number of people whose residence permits in Czechia had expired. Most of these were people whose granted international protection expired at the end of March. A total of 46.3 thousand people emigrated (6.1 thousand fewer than in the previous year), while 26.2 thousand people immigrated to the Czech Republic (2.4 thousand fewer than in the previous year). Citizens of Ukraine predominated in both migration flows.
