U.S. Population Over 165 Years

US Population 1850-2015

Since the beginning of the 21st century the movement of people around the globe has picked up. Factors such as globalization, wars and natural disasters have spurred an increase in the number of people emigrating or finding themselves forced into fleeing their homes and becoming refugees, looking for a new home. Resistance to newcomers is on the rise in many places and tensions run high when the topic of immigration comes up in public discourse. This set of circumstances made us wonder about the actual numbers of foreign-born people residing in the United States.

Today’s market size is the number of foreign-born people living in the United States in 2000 and in 2015. In the year 2000 foreign-born residents made up 12.4 percent of the U.S. population and in 2015 they accounted for 13.5 percent of all residents. The graph shows how the number of foreign-born persons in the population has trended over the last 165 years.
