Massachusetts sees sharp domestic out‑migration — about 182,000 residents left since 2020, study finds
Massachusetts has lost about 182,000 residents to domestic out-migration between April 2020 and July 2025, driven largely by younger adults and high living costs. Officials warn the trend threatens the state’s workforce, jobs and long‑term economic dynamism.
- Net domestic out‑migration (Apr 2020–Jul 2025): about 182,000 residents, per the Pioneer Institute.
- Younger adults affected: ages 26–34 account for a large share of departures, reducing future earners and parents (Pioneer Institute).
- International migration masked losses: roughly 230,000 added in 2022–2024 but fell sharply in 2025 (Commonwealth Beacon; UMass Donahue Institute).
- Jobs and unemployment: private‑sector jobs remain below 2019 (down ~18,000); unemployment rose to 4.8% in December 2025 (Pioneer Institute).
Overview
New analysis by the Pioneer Institute reports that Massachusetts lost roughly 182,000 residents to domestic out‑migration from April 2020 through July 2025. The institute describes the scale as “equivalent to losing roughly one‑and‑a‑half Cambridges.” The report notes this is not solely a pandemic spike — the outflow grew before COVID‑19 and has remained elevated.
Numbers and trends
State population still rose modestly to about 7.15 million by mid‑2025, helped by births and international arrivals, but underlying domestic losses persist (Commonwealth Beacon; UMass Donahue Institute).
Annual net domestic migration swung from a pandemic low of -47,954 in 2022, improved to -19,195 in 2024, then worsened to -33,340 in 2025, signaling volatility but a persistent long‑term outflow (UMass Donahue Institute).
Who is leaving
The Pioneer Institute highlights that departures are disproportionately younger adults, especially ages 26–34. Losing this cohort reduces not only the immediate labor pool but also future taxpayers, parents and long‑term economic dynamism.
Why people are leaving
Affordability is the central driver. Higher costs for housing, child care, health care and education push residents toward lower‑cost states such as Florida, North Carolina and Texas. For many younger residents, access to more affordable homes, lower taxes or faster job growth elsewhere makes relocation economically rational (Pioneer Institute; Commonwealth Beacon).
Jobs and the labor force
Massachusetts’ labor force reached about 3.9 million in 2024, driven largely by record international migration during 2022–2024 that added roughly 230,000 residents (Pioneer Institute; UMass Donahue Institute).
Despite international arrivals, private‑sector employment in Massachusetts remains below pre‑pandemic levels — down about 18,000 jobs (~0.55%) since January 2020, while the U.S. private sector grew by over 5% in the same period (Pioneer Institute).
Rising unemployment and regional comparison
Unemployment climbed to 4.8% in December 2025, up from a post‑pandemic low of 3.2% in April 2023. That rate was higher than nearby New England states — Connecticut (4.2%), Rhode Island (4.3%), Maine (3.2%), New Hampshire (3.1%) and Vermont (2.6%) — indicating job creation is not keeping pace with worker needs (Pioneer Institute).
International migration: a temporary mask
Net international migration peaked near 78,000 in 2024, helping offset domestic departures. But international arrivals slowed sharply in 2025 to roughly 40,000, producing a minimal net migration gain of about 6,900 for the year — a decline mirroring national patterns tied to federal policy shifts (Pioneer Institute; Commonwealth Beacon).
Projected population and housing stress
Mid‑2025 population was estimated at about 7.15 million, a modest year‑over‑year rise (~15,500), with births outpacing deaths by roughly 8,400 (Commonwealth Beacon). Researchers warn that if current trends persist, Massachusetts could see a 0.4% population decline (~28,000 people) from 2025–2035 unless stronger international inflows or policy changes occur (Mass.gov; Commonwealth Beacon).
Policy questions raised
The findings raise urgent questions for state leaders about competitiveness and cost structure. If Massachusetts cannot retain younger workers and families, it risks a smaller tax base, slower housing demand and weaker local businesses. Lawmakers and business leaders may consider changes to housing policy, taxes, child care support and other measures to improve retention (Pioneer Institute; Mass.gov).
Implications for the United States
Economic impact: A continued loss of talent from a major innovation and higher‑education hub could shift investment and jobs to faster‑growing states, dampening productivity in key sectors like biotech and professional services.
Labor and competition: Receiving states such as Florida, North Carolina and Texas have posted faster private‑sector growth and may increasingly attract skilled workers, intensifying regional competition for talent (Pioneer Institute).
Fiscal and political effects: Shrinking tax bases and changing demographics can influence debates on state tax policy, congressional apportionment and regional political power.
Social effects and practical steps: Sending communities may see fewer school enrollments and slower consumer demand while receiving states face housing and infrastructure pressures. Employers may respond by adjusting pay, benefits and flexibility or relocating operations to retain talent.
“Equivalent to losing roughly one‑and‑a‑half Cambridges,” the Pioneer Institute writes, underscoring the scale and demographic skew of the domestic outflow.
