On July 4, 1776, the Declaration of Independence was approved by the Continental Congress, setting the 13 colonies on the road to freedom as a sovereign nation. In July 1776, the estimated number of people living in the newly independent nation was 2.5 million. (Source: Historical Statistics of the United States: Colonial Times to 1970). Since then, the population of the United States has grown to over 311 million (estimated population on this July Fourth).
