Historical demography is important for research, but data have been limited to the most advanced countries. This column introduces newly estimated world populations for all polities from 1800 to 1938. Baseline estimates suggest the world population grew by 123%, from just above 1 billion in 1800 to 2.2 billion in 1938. Total population grew in almost all polities but the increase differed significantly, ranging from near stagnation in many African countries (and France and China) to over ten times in most immigration countries, including the US. The findings raise some challenging questions for the design of demographic policies.
