1970 United States census
The United States census of 1970, 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 1800 in which New York was not the most populous state – California overtook it in population in November 1962. 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 recorded a population of over 1 million (Houston).

California took over as the most populous state; New York had previously been ranked number one. While the entire country increased to more than 204 million persons, four states lost population, with West Virginia leading the list, down 8 and a half percent from 1960.
On April 25, 1973, the Census Bureau announced the results of a reanalysis of the 1970 census. The report estimated that the census undercounted approximately 5.33 million people, for a net undercount rate of 2.5%. This would have made the population approximately 208.7 million. Of those undercounted, an estimated 3.45 million were white, and 1.88 million were black.
