International Migration is Projected to Become Primary Driver of U.S. Population Growth for First Time in Nearly Two Centuries

International migration is projected to surpass natural increase (births minus deaths) as the principal driver of U.S. population growth by the middle of this century, according to three new series of population projections released today by the U.S. Census Bureau. This scenario would mark the first time that natural increase was not the leading cause of population increase since at least 1850, when the census began collecting information about residents’ country of birth. The shift in what drives U.S. population growth is projected to occur between 2027 and 2038, depending on the future level of international migration.
