Population of Czechia fell to 10.9 million in first three quarters of 2025

The population of the Czech Republic fell by 12,300 in the first three quarters of this year, dropping to just under 10.9 million. At the end of September, the country had exactly 10,897,178 inhabitants. The decline was caused by a significant excess of deaths over births; there were nearly 25,100 more people who died than children born from the beginning of the year through the end of September. This was the deepest natural population decrease recorded for the first three quarters since the establishment of the independent Czech Republic, the Czech Statistical Office (ČSÚ) announced on Friday.

Even the fact that roughly 12,800 more people moved to Czechia than left for abroad did not offset the decline. Year-on-year, both births and marriages decreased, while deaths and divorces were slightly higher compared to the same period last year.
