As of November 20, 2013 the population of the United States is 317,104,210. As of January 1, 2013, the United States had a total resident population of 317,174,000, making it the third-most populous country in the world. It is very urbanized, with 82% residing in cities and suburbs as of 2008 (the worldwide urban rate is 50.5%). Much of the country is nearly uninhabited. 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 2012 is 1.88 children per woman, which is below the replacement fertility rate of approximately 2.1. Compared to other Western countries, in 2011, U.S. fertility rate was lower than that of France (2.02) and the United Kingdom (1.97). 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%.
