Massachusetts Loses About 182,000 Residents to Other States, Study Finds — A Blow to the State’s Workforce and Long-Term Growth
Massachusetts lost about 182,000 residents to other U.S. states from April 2020 through July 2025, concentrated among 26-to-34-year-olds — a trend that threatens the state’s workforce, housing market and long-term economic growth despite past immigration offsets.
Key takeaways
- Net domestic out-migration: ~182,000 lost (April 2020–July 2025), per Pioneer Institute.
- Peak outflow: ~47,954 in 2022, per the UMass Donahue Institute.
- Young adults affected: losses concentrated among ages 26–34, weakening future labor supply and demand.
- International migration masked declines: large inflows through 2024 but easing in 2025, per Commonwealth Beacon.
What the numbers show
A new analysis by the Pioneer Institute finds a net domestic out-migration loss of roughly 182,000 people in Massachusetts between April 2020 and July 2025. The institute likens that figure to “losing about one-and-a-half Cambridges” over five years.
Annual patterns and Census revisions
The UMass Donahue Institute review of U.S. Census estimates shows domestic out-migration peaked in 2022 (≈47,954) and stayed negative through 2024 and into the July 2024–July 2025 window (losses roughly in the 33,000 range). Revisions tied to Census Vintage 2025 and methodology updates increased measured outflows in several years.
Who is leaving
The Pioneer Institute reports departures are concentrated among young working adults, mainly ages 26–34. That cohort typically drives hiring, home purchases, family formation and entrepreneurship — activities that support tax revenue and local spending.
“Those leaving tend to be younger, between the ages of 26 and 34, and the loss of their economic activity will affect the state for decades to come.” — Pioneer Institute
How immigration has masked the decline — and why that may change
Massachusetts saw a labor-force rebound in 2024 to about 3.9 million, driven largely by international migration. The state added roughly 230,000 residents from 2022 to 2024 thanks to record international inflows, according to the Pioneer Institute and reporting by the Commonwealth Beacon.
But international migration eased: international gains peaked near 78,000 in 2024 and fell to about 40,000 in 2025, signaling that the immigration buffer masking domestic losses may be receding.
Jobs, unemployment and lagging private-sector recovery
Private-sector employment in Massachusetts remains below pre-pandemic 2019 levels, with the Pioneer Institute estimating a decline of about 18,000 private-sector jobs (~-0.55%) since January 2020 — while U.S. private-sector job growth exceeded 5% in the same period.
Statewide unemployment rose to 4.8% by December, up from a low of 3.2% in April 2023, and higher than neighboring New England states such as Connecticut (4.2%) and Rhode Island (4.3%), per the Pioneer Institute analysis.
Economic risks tied to losses of younger workers
Losing workers in their late 20s and early 30s reduces future labor supply, entrepreneurship, homebuying and child rearing — weakening long-term tax revenue and consumer demand. The Pioneer Institute emphasizes that one in five Massachusetts workers is an immigrant, a strength that also creates vulnerability to federal immigration policy shifts.
Contributing factors: high costs and housing shortages
Analysts point to high living costs — especially housing shortages and affordability gaps — as a primary driver. State housing analysis at Mass.gov highlights chronic gaps between housing supply and household demand, particularly for more affordable options. Child care, health care and education costs also contribute to decisions to leave.
Data revisions and methodology
Census Vintage 2025 updates and UMass Donahue Institute adjustments changed earlier figures by revising the 2020 Census base and methodology. Those revisions increased measured domestic outflows in several years and clarified how international migration offset losses; see the UMass Donahue Institute summary.
Policy implications and risks
If national immigration slows further in 2026, Massachusetts risks shifting from net growth to net decline. Policymakers and business leaders face trade-offs: invest in more housing and lower living costs, boost job creation in worker-attracting sectors, or redesign tax and regulatory policies to influence residence decisions. Each choice carries political and fiscal consequences.

Implications for Las Vegas, Nevada
The Massachusetts out-migration story presents both risks and opportunities for Las Vegas. Below are practical implications across economic, political, social and cultural dimensions, plus policy and business recommendations.
Economic impact
- Talent and business opportunities: Openings for tech, health care and hospitality workers relocating from Massachusetts can help Las Vegas employers fill roles and spur startups.
- Recruiting advantages: Emphasize lower housing costs and no state income tax to attract professionals aged 26–34 seeking affordability and family-friendly markets.
Political consequences
- Policy narratives: Use migration trends to inform local messaging on tax competitiveness and housing reform.
- Inter-state migration politics: Expect pressure for incentives to attract firms and relocating families as states compete for residents.
Social effects
- Demographic shifts: In-migration can change housing demand, school enrollment and public-service needs.
- Community integration: Newcomers from Massachusetts may require targeted programs to connect with local job markets and civic life.
Cultural relevance
- Talent mix: Professionals from Massachusetts often bring biotech, higher-education and advanced-services experience that can diversify Las Vegas’ economy.
- Lifestyle appeal: Market outdoor access, cultural amenities and affordability to attract those priced out of New England.
Practical applications for residents and policymakers
- Workforce development: Coordinate with colleges and training programs to welcome newcomers and speed credential recognition.
- Housing policy: Plan for mixed-income housing and transit investments in neighborhoods likely to attract relocating professionals.
- Business attraction: Tailor recruitment packages emphasizing lower taxes, housing affordability and targeted industry clusters.
Bottom line: For Las Vegas, Massachusetts’ population shifts are both a cautionary tale and an opportunity. Local leaders can learn from the drivers of out-migration — notably high housing and living costs — and design strategies to attract, integrate and retain new residents while managing growth pressures.
