Population is the number of people that inhabit a place, whether it be a city, nation, countryside, island or even an entire planet.
During the 1970s, there was much worry that because of the population explosion, the world would get overcrowded. One man named Doctor Hiram Gulliver went to extreme measures to remedy this problem, when he decided to shrink the population to two-inches tall.
The population of Smallville was 90,000 in 1990.
