   Social Science / How Many People Are In the United States

It is not difficult to find the information about how many people there are in the United States, because the U.S. Census Bureau¹ regularly publishes the population data. In the middle of 2012 they stated the following:

• The population of the USA is over 314 165 191 people

It means that by population the United States is the third largest country in the world (following the People’s Republic of China and India). It is also known that the world’s population equals to about 6.8 billion people. Thus, about 4.5% of all people on the Earth live in the USA.

The first census, conducted in 1790, estimated that there were 3 929 214 citizens in the country. As you can easily calculate, since then the US population has become almost eighty times greater. The 100 000 000 mark was crossed in 1915, the 200 000 000 mark in 1967, and the 300 000 000 mark in 2006.

According to the expectation of the U.S. Census Bureau, over the next decades the population of the USA will reach the following estimates.



As expected, the population of the USA will reach 400 000 000 people in 2042.

The fertility rate in the USA is 2.09. It means that every American woman gives birth, on the average, to 2.09 children during her life. This rate does not mean the tendency to the growth of population, but the number of citizens constantly increases due to immigrants. Every eight seconds a new American is born, and every eleven seconds one death is registered. But every thirty seconds one migrant becomes an American.

More than eighty percent of the USA population live in cities and suburbs. California and Texas are the most populous U.S. states, and New Jersey has the highest density ration in the country. More than 430 persons live on a square kilometer there.

The table below will give you information about the eleven most populous states by August 15, 2012.
