Massachusetts Loses About 182,000 Residents to Domestic Out-Migration, Threatening Workforce and Long-Term Growth
Massachusetts has lost about 182,000 residents to domestic out-migration from April 2020 to July 2025, a sustained trend driven by affordability and competitiveness that threatens the state’s workforce, growth, and long-term economic stability.
Key takeaways
- Large net domestic loss: ~182,000 residents left Massachusetts between April 2020 and July 2025, with a net loss of ~33,000 in the year ending June 2025, ranking the state among the highest domestic out-migration nationwide (Pioneer Institute, Commonwealth Beacon).
- Younger adults most affected: Adults ages roughly 25–44 make up the largest share of out-migrants, implying losses in prime earning and family-forming years (Boston Indicators).
- International migration masked effects: International arrivals added roughly 230,000 residents from 2022–2024, but net international migration fell sharply in 2025, reducing that offset (UMass Donahue Institute).
- Economic risk: Private-sector employment remains below pre-pandemic levels and unemployment has risen, signaling potential long-term effects on growth and tax revenue (Pioneer Institute).
Scale and trends
New research from the Pioneer Institute documents a sustained, structural pattern of domestic out-migration in Massachusetts. The institute estimates the state lost about 182,000 residents to domestic moves between April 2020 and July 2025 — roughly the equivalent of losing one-and-a-half cities the size of Cambridge.
Annual state-level estimates show a net loss of about 33,000 residents to domestic migration in the year ending June 2025, placing Massachusetts among the top states for domestic population loss (Commonwealth Beacon; UMass Donahue Institute).
Who is leaving
Data from Boston Indicators show the departing population skews young: adults ages roughly 25–44 represent the largest share of out-migrants. By 2022, younger age groups accounted for about three-fifths of age-group losses, meaning the state is losing workers in their prime earning and family-forming years.
Why this matters: Younger, working-age residents drive taxes, consumption, innovation, and the long-term labor supply. Their loss reduces income-tax receipts and can hollow out local talent pools for decades.
Economic and labor-force impacts
The Pioneer Institute reports private-sector employment in Massachusetts is still below January 2020 levels by about 18,000 jobs (≈‑0.55%). Over the same period the U.S. private sector grew by roughly 5%, with faster-growing states posting double-digit gains.
Massachusetts’ labor force reached an estimated 3.9 million in 2024, but much of that rise resulted from international arrivals, not domestic retention. From 2022–2024, state analyses estimate roughly 230,000 residents were added through international migration (Pioneer Institute; UMass Donahue Institute).
Unemployment has risen: the Pioneer Institute reported the statewide unemployment rate increased to about 4.8% as of December, up from a post-pandemic low of 3.2% in April 2023 — higher than neighboring New England states.
International migration was a temporary mask
International arrivals temporarily masked domestic losses: net international migration added roughly 230,000 residents from 2022–2024, peaking near 77,957 in 2024 (Pioneer Institute; UMass Donahue Institute).
Those gains fell sharply in 2025: UMass Donahue reports net international migration declined to about 40,240 in 2025 — roughly a 48% drop from 2024. Nationally, the Census Bureau documented a historic fall in net international migration from 2.7 million (July 2023–June 2024) to 1.3 million (July 2024–June 2025), with projections of further declines into 2026 (UMass Donahue Institute; Commonwealth Beacon).
Why researchers call it structural
Analysts at the Pioneer Institute argue the pattern predates the pandemic and has continued since, suggesting drivers beyond short-term remote-work shifts. They point to affordability, tax and regulatory competitiveness, and quality-of-life trade-offs as likely root causes.
Interpretation: If out-migration reflects structural policy and cost issues, remedies will require sustained policy changes rather than temporary fixes.
Implications for California
California leaders should watch Massachusetts as a cautionary example. Both states share traits — higher taxes, expensive housing in key metros, concentrated tech and health sectors — that can accelerate out-migration. The Massachusetts case illustrates how persistent population loss can weaken a state’s workforce, tax base, and competitiveness.
Potential impacts for California:
- Talent loss: Employers may face higher recruitment costs and slower expansion if younger workers depart.
- Revenue risk: Declines in working-age residents can reduce income-tax receipts and business activity.
- Competition for growth: States with lower housing costs and taxes may continue to attract residents and firms.
Social effects and practical implications
Population shifts change demand for housing, transportation, schools, health care, and elder services. Local budgets, workforce planning, and employers must adapt.
Practical consequences:
- Housing and commuting pressures as families seek affordability elsewhere.
- Shifting demands on services and schools that require updated planning.
- Employers and workforce agencies must invest in retention, training, and recruitment.
Practical steps for state leaders and employers
Policy and business responses can blunt the effects of out-migration. Recommended actions include:
- Focus on affordability: Expand housing supply and lower living costs to retain younger workers.
- Boost competitiveness: Streamline regulation and support business growth to attract and retain high-paying firms.
- Invest in training: Public-private workforce programs can address short-term shortages while long-term reforms take hold.
- Monitor migration data: Timely state-level statistics help officials respond quickly to changing trends.
