State officials say New Hampshire's projected population is expected to reach 1.4 million in 2040, an increase of nearly 9 percent from the population at the 2010 census.
The Office of Energy and Planning says the projected number of births is expected to decline very slightly over this time period, from 66,000 between 2010 and 2015 to 65,000 between 2035 and 2040.
At the same time, though, deaths are projected to increase sharply, from 56,500 between 2010 and 2015 to nearly 96,000 between 2035 and 2040. Thus, the projected rise in total population between now and 2040 will be due to continued migration into the state.
The statewide number of people age 65 and over is projected to increase from 178,268 in 2010 to 408,522 in 2040.
