New Hampshire was the second fastest growing state in New England over the last decade, according to U.S. Census Bureau figures released Monday.

The state’s resident population on April 1 was 1,377,529, a 4.6 percent increase from 2010. Massachusetts was the fastest growing state in New England, seeing a 7.4 percent increase. That matches the 7.4 percent resident population increase in the nation as a whole.

With more deaths than births, all of New Hampshire’s population gain in recent years has been due to people moving into the state, according to an analysis published in December by the University of New Hampshire’s Carsey School of Public Policy. That in-migration had slowed and then stopped after the Great Recession but has begun returning, researchers said.

Previous research also has shown that recent migration gains were greatest among young adults. That helps offset the mortality rate among older residents at a time when the three northern New England states have the oldest median ages in the country.

The data released Monday also included the population counts to be used for apportioning the seats of the U.S. House. Those totals include overseas military and federal civilian employees and their dependents living with them overseas. New Hampshire’s overseas population decreased from 4,975 in 2010 to 1,560 on April 1.
