Based on the information in the above chart, how did the American population change between 1980 and 2000?

The population growth of 32.7 million people between 1990 and 2000 represents the largest census-to-census increase in American history. 2 The previous record increase was 28.0 million people between 1950 and 1960, a gain fueled primarily by the post-World War II baby boom (1946 to 1964). Total decennial population growth declined steadily in the three decades following the 1950s’ peak before rising again in the 1990s

In percentage terms, the population increase of 13.2 percent for the 1990s was higher than the growth rates of 9.8 percent for the 1980s and 11.4 percent for the 1970s. The 1990s growth rate was similar to the 13.4 percent growth in the 1960s and was well below the 18.4 percent growth for the 1950s
