Push and Pull Factors for Pennsylvania Migration: Why People Leave and Stay

Pennsylvania presents a mixed migration picture—losing domestic migrants net since 2010, but gaining internationally. Here's what drives decisions.

Push Factors (Reasons to Leave)

High Cost of Living (Relative to Income)

Housing costs up 45% since 2015 (Zillow); wages up 25%. Property taxes: 12th highest nationally. Philadelphia/South Central/Lehigh Valley hottest markets. Rural areas affordable but job-poor.

Tax Burden

Flat 3.07% state income tax + local earned income tax (up to 3.87% in Philly) + 6% sales tax + high property tax + inheritance tax (4.5–15%). Retirees flee to FL, TN, SC, NC.

Job Market Structural Issues

Unemployment ~3.5% (low), but: manufacturing decline (steel, auto), energy transition (coal), rural brain drain. Tech/healthcare/ed concentration in Philly/Pittsburgh—rest of state lags.

Climate and Infrastructure

Cold, snowy winters (Erie: 100"+ snow); aging roads/bridges (D+ ASCE grade); combined sewer overflows; slow broadband rollout rural.

Population Stagnation

0.1% annual growth (2020–2023). Outmigration of 25–44 age group. Aging population (2nd oldest median age: 40.9).

Pull Factors (Reasons to Move In/Stay)

Economic Anchors

• Philly/Pittsburgh metros: 75% of state GDP. Eds & meds (UPenn, Penn State, Pitt, CMU, Drexel, Temple), pharma, fintech, robotics, life sciences
• Logistics: I-80/I-81/I-76 corridors; 40% US population within 500 miles
• Energy: Marcellus Shale (gas), growing solar/wind, nuclear (Limerick, Peach Bottom, Susquehanna)

Education

Top-tier: UPenn (Ivy), Carnegie Mellon, Penn State, Pitt, Lehigh, Villanova, Swarthmore, Haverford. K-12: well-funded suburban districts (Main Line, Mt. Lebanon, Lower Merion).

Quality of Life

• Outdoor: Poconos, Alleghenies, Laurel Highlands, 121 state parks, 2.2M acres state forest
• Culture: Philly museums, orchestras, theater; Pittsburgh Cultural District; Amish Country tourism
• History: Independence Hall, Gettysburg, Valley Forge, 169 UNESCO sites
• Cost/amenity balance: Urban sophistication at 60% NYC/DC cost

Geographic Position

Northeast corridor access: NYC 1.5h, DC 2.5h, Boston 5h by train. International airports (PHL, PIT). Great Lakes access (Erie).

Net Assessment

Pennsylvania wins on institutions, location, nature, and urban value. Loses on taxes, winter, rural decline, and demographic momentum. Remote work helps retain talent; tax reform could reverse outflow.
