Population change - 1st quarter of 2023

Number of immigrants from abroad remains high

Code: 130080-23

The population of the Czech Republic increased by 23.1 thousand to 10.85 million during the first quarter of the year. A positive balance of international migration (31.3 thousand), which continued to be dominated by citizens of Ukraine, especially those with temporary protection granted stood behind the increase. Due to natural change, the population of the Czech Republic decreased (by 8.2 thousand). The number of live births, deaths and marriages decreased year-on-year.

According to the population balance of the CZSO, the population of the Czech Republic was 10.85 million as at 31 March, including those with temporary protection granted in connection with the war in Ukraine. "During the first quarter of this year, a total of 41.3 thousand people immigrated to the Czech Republic from abroad. Compared to the first quarter of 2022, when a migration wave of almost 150,000 people arrived from Ukraine, the number was only a quarter, but the number of immigrants remained high than in previous years", says Michaela Němečková from the Demographic Statistics Unit. Three quarters of the immigrants were citizens of Ukraine, while the second most numerous Slovaks accounted for only 4% of the immigrants. The number of emigrants abroad was recorded at 10.0 thousand.

The year-on-year decline in the birth rate, which began in early 2022, continued this year. In the period from January to March, a total of 22.0 thousand babies were born alive, by 2.7 thousand (or 11%) fewer year-on-year. In terms of birth order, the number of first-born children decreased relatively the least (by 8%), while the number of children in the third or higher order decreased the most (by 18%). The share of live births outside marriage reached 49.2%.

The number of deaths was 30.3 thousand, by 1.9 thousand lower than in the first quarter of 2021, but comparable to the same period in 2020 or 2019. In calendar months, the highest number of deaths occurred in January (11.4 thousand). There were 3.5 thousand couples entered into marriage in the period from January to March, by 1.0 thousand less than a year earlier. However, last year's total for the first quarter was boosted by attractive dates in February (e.g. 22 February 2022).
