UNH Research Confirms Migration is Biggest Driver of Population Change in N.H.
DURHAM, N.H.—The Granite State continues to depend on migration for the majority of its population growth, according to new research released by the Carsey School of Public Policy at the University of New Hampshire. Population growth has recently started to increase after a decline during the recession and its aftermath. The state’s population grew by more than 7,000 annually between 2016 and 2018, and most of the gain resulted from more people moving to the state from other U.S. destinations. Immigration also contributed to the gain. In contrast, the excess of births over deaths has diminished so much that its contribution to population gain is now minimal.
“Migration is important to New Hampshire’s future because it brings in younger people of working age at a time when the state’s workforce is aging,” said Kenneth Johnson, professor of sociology and senior demographer. “In-migrants to the state have been better educated than those leaving and that has resulted in an increase to the state’s store of intellectual capital.”
Johnson noted that while New Hampshire is often characterized as a state where residents’ lineage goes back generations, in reality it is one of the most mobile populations in the country. Only 42% of the state residents were born in New Hampshire, far less than for New England (58%) or the United States (59%).
“The future economic and social well-being of New Hampshire communities depends on their ability to anticipate change and respond appropriately,” said Johnson. “This analysis of how the state’s population is growing and changing can help to inform policy and contribute to the efforts of policymakers, nonprofits and businesses to consider the future needs of the state’s people, institutions and organizations.”
The Carsey School of Public Policy is nationally recognized for research, policy education and bringing people together for thoughtful dialogue to address important societal challenges. The school develops and facilitates innovative, responsive and equitable solutions at all levels of government and in the for-profit and nonprofit sectors.
