The US population has grown since independence, with census data collected every decade since 1790. The growth is due to natural increase and net international migration. The Census Bureau provides projections, with an estimated population of 570,954,000 by 2100.
The population of the United States has continued to increase since independence. A census has been conducted at the beginning of every decade since 1790. Numbers are captured in a variety of ways, including door-to-door polling, but the Census Bureau has never counted every individual. In addition to general population information, the Census Bureau also collects other data ranging from ethnicity to income and housing.
US population growth is attributable to a positive difference between immigration and emigration (net international migration) and to the birth rate exceeding the death rate (natural increase). Over half of the recent increases are due to natural increase.
The Census Bureau also provides projections for the future, but these are highly speculative. We have shown their “average estimates” that extend to 2100.
