Key Findings
The population of New Hampshire grew by 5,500 (0.4 percent) to 1,366,000 between July of 2019 and July of 2020, according to new Census Bureau estimates. This was the largest population percentage increase in New England. In contrast, the region as a whole and four of its six states lost population between July 2019 and July 2020, due in part to mortality associated with the COVID-19 pandemic. New Hampshire’s population percentage increase has been the largest in New England in each of the last three years. New Hampshire and Maine gained population in each of the last four years, and Massachusetts grew in three of the four years. In contrast, Connecticut, Rhode Island, and Vermont all lost population in at least three of the last four years. All of New Hampshire’s population gain in recent years has been due to migration, as recent Carsey research shows there have been fewer births than deaths in the state. Maine and Vermont also had more deaths than births in recent years. This is likely to continue in the near-term because of mortality increases associated with COVID-19. Both New Hampshire and New England’s overall population gain during the past four years has been considerably smaller than gains in many states in the south and west.
