Question 1067201
if it doubles every 50 years, then 2.5 million in 1950 * 2 = 5 million in 2000 * 2 = 10 million in 2050.


of course, you are probably talking billion, rather than million.


the world populations statistics are:


1950 = 2.5 billion
2000 = 6.0 billion
2050 = 9.3 billion (projected)


that's almost double every 50 years but not quite.
