In this brief, Carsey Senior Demographer Kenneth Johnson reports that New Hampshire’s population reached 1,402,054 on July 1, 2023, an increase of 24,500 residents since April 1, 2020, according to new Census Bureau estimates. New Hampshire gained 3,100 residents last year compared to 11,500 and 8,800 in the two preceding years, respectively. The state gained population even though it had 6,600 more deaths than births in the past three years because nearly 31,000 more people moved to the state than left it.

All ten of New Hampshire’s counties gained population between 2020 and 2023, compared to 52 percent of all counties nationwide. However, the magnitude of the population increases varied from county to county. Such widespread population gains are surprising given that deaths exceeded births in nine of New Hampshire’s ten counties.

Although migration fueled population gains in all ten New Hampshire counties from 2020 to 2023, the pace of growth slowed between July 2022 and July 2023.

These new Census data underscore the continuing importance of migration to the state’s demographic future. Such migration gains result both from attracting migrants to the state and retaining existing residents. This emphasizes the importance of developing policies that encourage current residents to remain and new migrants to come to New Hampshire, as well as policies that ensure New Hampshire communities are prepared to support these migrants.
