The 2014 estimated U.S. population was 318,857,056. Of this number 23.3 percent of the population was under 18 and 2.4 percent of the population identified with two or more races. In 2013, 50.8 percent of the American population in 2013 was female, and 12.9 percent identified as foreign-born.
The most recent U.S. census was taken in 2010, when the population was found to be 308,758,105. The census department's 2013 and 2014 estimates were based on this data. Many of the estimates spanned the time period from 2009 to 2013, including the percentage of people with a second language spoken at home, which was 20.7 percent.
The percentage of the population under the age of 5 in 2013 was 6.3 percent, while 14.1 percent were over 65. More than 5 percent of the population was Asian, and 17.1 percent was Hispanic. Many other races were included in the census, including Native Hawaiian or Pacific Islanders at just 0.2 percent of the population.
Almost two-thirds of Americans owned homes between 2009 and 2013, and over a quarter of the population lived in multi-unit housing. While 86 percent of the American population were high school graduates, the percentage of Americans with a bachelor's degree was 28.8 percent. The country had over 21 million veterans identified in the census.
