As of January 3,
2015, the
United States has a total resident population of 320,064,285, making it the third-most populous country in the world. It is very urbanized, with 81% residing in cities and suburbs as of 2014 (the worldwide urban rate is 54%).
California and
Texas are the most populous states, as the mean center of
U.S. population has consistently shifted westward and southward.
New York City is the most populous city in the United States.
The total fertility rate in the United States estimated for
2013 is 1.87 children per woman, which is below the replacement fertility rate of approximately
2.1. Compared to other
Western countries, in
2012,
U.S. fertility rate was lower than that of
France (2
.01),
Australia (1.93) and the
United Kingdom (1.92). However, U.S. population growth is among the highest in industrialized countries, because the differences in fertility rates are less than the differences in immigration levels, which are higher in the U.S.
The United States Census Bureau shows population increase of 0.75% for the twelve-month period ending in July 2012. Though high by industrialized country standards, this is below the world average annual rate of
1.1%.[9]
There were over
158.6 million females in the United States in 2009. The number of males was 151.4 million. At age 85 and older, there were more than twice as many women as men.
People under 20 years of age made up over a quarter of the U.S. population (27.3%), and people age 65 and over made up one-eighth (12.8%) in 2009.[12]
The national median age was 36.8 years.[12]
The United States Census Bureau defines
White people as those "having origins in any of the original peoples of
Europe, the
Middle East, or
North Africa. It includes people who reported "
White" or wrote in entries such as
Irish,
German,
Italian, Lebanese,
Near Easterner,
Arab, or
Polish."[13]
Whites constitute the majority of the U.S. population, with a total of about 245,532,
000 or 77.7% of the population as of 2013. There are 62.6% Whites when Hispanics who describe themselves as "white" are taken out of the calculation.
Despite major changes due to illegal and legal immigration since the
1960s and the higher birth-rates of nonwhites, the overall current majority of
American citizens are still white, and
English-speaking, though regional differences exist.
The American population almost quadrupled during the
20th century—at a growth rate of about 1.3% a year—from about 76 million in
1900 to 281 million in
2000. It reached the
200 million mark in
1968, and the
300 million mark on
October 17,
2006.[14][15]
Population growth is fastest among minorities as a whole, and according to the
Census Bureau's estimation for 2012, 50.4% of
American children under the age of 1 belonged to minority groups.[16]
Hispanic and Latino Americans accounted for 48% of the national population growth of 2.9 million between July 1,
2005, and July 1, 2006.[17]
Immigrants and their U.S.-born descendants are expected to provide most of the U.S. population gains in the decades ahead.[18]
The Census Bureau projects a U.S. population of 439 million in 2050, which is a 46% increase from
2007 (
301.3 million).[19] However, the
United Nations projects a U.S. population of 402 million in 2050, an increase of 32% from 2007 .[20] In either case, such growth is unlike most
European countries, especially
Germany, and
Greece, or
Asian countries such as
Japan or
South Korea, whose populations are slowly declining, and whose fertility rates are below replacement.
Official census report, reported that 54.
4% (2,
150,926 out of 3,953,593) of births in
2010, were non-Hispanic white. This represents an increase of 0.34% compared to the previous year, which was 54.06%.
