New Hampshire’s Population Growth Driven by Migration

From 2010 to 2022, U.S. Census Bureau estimates show New Hampshire’s population growth was almost entirely reliant on people moving to the state from other states or internationally. During these twelve years, the number of deaths in New Hampshire began to outnumber births, and the state’s population would have declined annually without migration beginning in approximately 2017.  Migration from other states has increased during this period, particularly in the years following the beginning of the COVID-19 pandemic. Based on these estimates, however, more than half of all population growth from 2010 to 2022 was due to international migrants to New Hampshire, which were consistently positive despite lower levels in 2010 and between 2017 and 2021.
