The 1970 United States census, conducted by the Census Bureau, determined the resident population of the United States to be 203,392,031, an increase of 13.4 percent over the 179,323,175 persons enumerated during the 1960 census.

This was the first census since 1820 in which New York was not the most populous state—California overtook it in population in January 1963. This was also the first census in which all states recorded a population of over 300,000, and the first in which a city in the geographic South—Houston—recorded a population of over 1 million.
