Population of Czechoslovakia 1910-1990
The population of Czechoslovakia did not grow significantly between 1910 and 1921, and in regards to gender the male population actually decreased by around 50 thousand. The population drastically decreases from 1930 to 1946/7, from 14.7 to 12.2 million people. These changes are mostly as a result of both World Wars, and the rearranging of Czechoslovakia's borders, particularly in the east. After 1946/7 the population grows quite gradually, and is almost reaches it's pre-WWII height again in 1970, with 14.35 million people.
