What are the 2014 census population figures?

The world's population was 7.2 billion in 2014, according to the U.S. Census Bureau. Almost 319 million of those people lived in the United States. The Census Bureau calculates population figures annually by factoring in births, deaths and migration patterns.

The world's most populous countries are China and India, which together account for about a third of the people on earth. The largest U.S. states are California, Florida, Texas and New York, which together make up about a third of the United States' population. Wyoming, Vermont, North Dakota, South Dakota and Alaska had the fewest people in 2014, with each state registering less than 1 million in population.
