The share of U.S. population growth attributable to immigrants hit 48% for the fiscal year ended June 30, 2018, up from 35% in fiscal 2011.
The general fertility rate in 2017 for women age 15 to 44 was 60.2 births per 1,000 women—the lowest since the government began tracking it more than a century ago, according to the National Center for Health Statistics.
Fourteen states and the District of Columbia drew on immigration for more than half of their growth last fiscal year, including Florida, Kansas, Michigan, Ohio, Pennsylvania and Virginia.
The figures encompass people moving to and from the U.S., including an influx from Puerto Rico in the wake of Hurricane Maria in 2017. Migration from Puerto Rico is counted as immigration by the Census Bureau though the island is a U.S. territory and its residents are U.S. citizens.
Since 2010, the biggest share of immigrants—41%—has come from Asia, according to separate census figures. A fifth, or 21%, has come from Mexico and Central America.
