Poland Historical Population

Poland’s population saw a steady growth rate in the early 20th Century, a negative growth rate during the second world war & then again steady growth till 1980. After the 1980s population growth is slow & in last two decades, it’s fixed at 38 million. Negative growth can be attributed to falling birth rates and considerable emigration.

In 1950, the median age was 25.8 & Today it is 41.7. Emigration overseas also impacted population growth. The number of children born in Polish families (TFR of 1.31, down from 2 in 1990) is one of the lowest in Central Europe. In recent years it improved a little & now stands at 1.42. Let’s look at Polish Population from the Year 1920 to 2020.
