Based on 2015 population estimates from the U.S. Census Bureau

As of July 1, 2017, the United States has a total resident population of 325,350,377 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 2016 is 1.82 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 a 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%.

There were about 125.9 million adult women in the United States in 2014. The number of men was 119.4 million. At age 85 and older, there were almost twice as many women as men (4 million vs. 2.1 million). People under 21 years of age made up over a quarter of the U.S. population (27.1%), and people age 65 and over made up one-seventh (14.5%). The national median age was 37.8 years in 2015.

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." 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. Non-Hispanic whites make up 62.6% of the country's population. Despite major changes due to 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.
