Undated: U.S. Census

From 1950 to 1960, the population of the United States increases from about 151 million to nearly 180 million, a jump of more than 18 percent. The percentage increase is the largest since the first decade of the 20th century. (The Census Bureau's definition of the post-World War II "baby boom" includes births from 1946 to 1964.)
