The population of the Czech Republic fell by approximately 32,600 in the first quarter of 2025, bringing the total number of inhabitants to 10,876,875, according to data released by the Czech Statistical Office (ČSÚ). The decline was attributed to both natural population loss—where deaths exceeded births—and a negative balance in foreign migration. Between January and March, the country experienced 18,100 births, a 14% decrease compared to the same period last year. The ongoing decline in birth rates has now continued for four consecutive years. Of the children born, 8,400 were firstborns, around 7,000 were second-born, and approximately 2,700 were third or subsequent children. Nearly half (48.1%) of all births took place outside of marriage. The majority of mothers were born between 1993 and 1996. At the same time, 30,600 deaths were recorded, marking a 3% increase year-on-year. Mortality was most prevalent among those aged 70 and above, with the highest number of deaths occurring in the 80–84 age group (5,300), followed by the 75–79 age group (5,200). Marriage numbers also declined, with just under 3,000 couples marrying during the first quarter—12% fewer than in the same period last year. This marks the third consecutive year of decline in marriage figures. Most grooms were aged 30 to 34, while brides were typically aged 25 to 29. Meanwhile, 4,400 divorces were recorded, a slight year-on-year decrease of 2%. Most divorces involved couples who had been married for five, six, or two years, corresponding with marriage peaks in 2019, 2018, and 2022. Around 60% of divorces involved at least one minor child. Foreign migration also contributed significantly to the population decline. Approximately 46,300 people emigrated from the Czech Republic in the first quarter, 6,100 fewer than in the same period last year. At the same time, 26,200 people immigrated—2,400 fewer than last year. In both emigration and immigration figures, Ukrainian citizens predominated, many of whom had previously been granted temporary protection due to the war in Ukraine. According to the Czech Statistical Office, the decline in population linked to migration was largely due to the expiration of temporary stays and international protection status. A high number of those leaving the country had been granted temporary protection in previous years, and their departure contributed to the negative migration balance.
