A report out this week by the BPDA's research division shows Boston's population could reach a number not seen since the 1950s, in large part due to people moving here from overseas - many of them college students.
By 2030, the report says, Boston's population should hit 760,000. Boston's peak population of 801,444 came during the 1950 census, after which the city saw continued declines until it hit 562,994 in 1980. It then began to slowly rise, with growth becoming more explosive after 2010, according to BPDA figures.
According to the BPDA, the growth is being driven largely by international migration. Although roughly 57,000 people now move to Boston from other parts of the US, that's balanced by a nearly equal out migration from Boston elsewhere. Bostonians now have about 3,700 babies a year, but roughly 6,700 people from outside the US are now moving into the city each year, according to the BPDA.
This positive net gain is due to migration due to the large influx of 17 to 24 year olds.
The report adds:
While the 20-29 cohort is projected to remain the largest, the 2030 projections show increases in the older age cohorts.
BPDA projections project decreases in the population share of 15 to 29 year olds, and increases in the share of the 65+ population.
