The first decennial census in the United States showed a population of just under four million people. Today, the U.S. population is estimated at more than 310 million. The last census showed that the US had a .77 percent increase in population. According to the Census, "The combination of births, deaths and net international migration increases the U.S. population by one person every 17 seconds,".

While that figure may sound high the U.S. population is actually growing at a slower rate than other nations. In 2009, there was an almost one percent increase in the birth rate, which was seen as a post recession baby boom. Here you will find a list of the U.S. population every ten years from the first official census in 1790 to the most recent in 2000.
