Code: 130080-18

At the end of June this year, the Czech Republic had a total of 10.625 million inhabitants. The population increased by 15.4 thousand during the first half of the year, as a consequence of net migration, which amounted to 17.7 thousand. The number of live births (55.7 thousand) was lower than the number of deaths (58.1 thousand).

According to the preliminary statistical balance the population of the Czech Republic increased by 15.4 thousand to 10 625.4 thousand from 1st January to 30th June of 2018. The whole increase resulted from the international migration, which balance amounted to 17.7 thousand persons. The balance of natural change was negative, as the number of deaths exceeded the number of live births by 2.3 thousand.

According to the preliminary data a total of 55.7 thousand children were born alive from January to June of 2018, by 0.5 thousand fewer in year-on-year comparison. There was a moderate decrease in both the number of children born to married women (28.6 thousand) and the number of children born to unmarried women (27.1 thousand). The share of live births outside marriage stood at 48.7% and was slightly lower than a year before (48.9% in the 1st half of 2017) for the first time. The most children were born to women aged 30, the first born children to women aged 27 years.

In the first half of 2018, according to the preliminary data there were 58.1 thousand deaths, alike in the first half of 2017. Among the deceased people there were total of 29.2 thousand men and 28.8 thousand women. The most of deceased people, 9.9 thousand, were aged 85–89 years due to high number of deceased women in that age group. Owing to higher mortality men than women and numerically large cohorts of births after World War II, men aged 70–74 years were predominant among deceased men. A total of 156 children died during their first year of life, 15 more than in the 1st half of the previous year. The infant mortality rate increased slightly year-on-year by 0.3 to 2.8‰.

According to the preliminary data a total of 20.9 thousand couples entered into marriages from January to June of 2018, by 1.1 thousand more than in the 1st half of the previous year. The almost half of them, 10.3 thousand, entered into the marriage during June. It represented the highest monthly number of marriages since 2009. Three-quarters of grooms and brides entered into their first marriage. Most frequent grooms were at the age of 29 and most brides at the age of 27.

According to the preliminary data, the Czech courts issued 11.9 thousand decisions about divorces from January to June of 2018. It was by 1.2 thousand fewer than in the same period of 2017. The almost half of the divorce proceedings (46%) was initiated by a joint petition of both man and woman. The divorces of marriages with minors (7.0 thousand) outweighed the divorces of marriages without minors (4.8 thousand). The divorce concerned a total of 11.0 thousand minors. The average duration of marriage at divorce was 14.9 year.

Due to international migration, the population of the Czech Republic increased by 17.7 thousand people during the first six months of 2018. The value of migration balance was higher by 5.2 thousand than in the 1st half of 2017. The international migration flows of both immigrants and emigrants were increased in year-on-year comparison. A total of 29.2 thousand people immigrated to the Czech Republic from abroad, by 7.8 thousand more than a year before. On the other hand, a total of 11.5 thousand inhabitants emigrated from the Czech Republic, by 2.6 thousand more than in the 1st half of 2017. Higher amounts of immigrants and emigrants were significantly affected by migration of citizens of Ukraine. The highest positive migration balance in the 1st half of 2018 was registered with citizens of Ukraine (5.6 thousand), the second highest migration balance with citizens of Slovakia (2.7 thousand), followed by Romanian and Bulgarian nationals (each 1.1 thousand).
