Suffolk County, New York

• Income premium: Households earn well above the national median, supporting strong retail and housing markets.
• Aging population: Median age of 42 is materially above the U.S. norm; succession planning and senior-services demand are real factors.

• Largest sector: Health Care and Social Assistance employs 111,168 workers (21.9% of tracked sectors), at an average wage of $73,745.
• Economic scale: Regional GDP of $139B (2024).
• Wage stratification: Professional, Scientific, and Technical Services averages $105,200 while Accommodation and Food Services averages $35,390, a 3.0x spread in the same local economy, with implications for workforce development and talent strategy.

• Top specialization: Transit and Ground Passenger Transportation concentrates at 5.86x the national norm, top-decile concentration, the kind of signature sector that defines a region's economic identity to site selectors.
• Cluster depth: 6 sub-sectors register LQ ≥ 1.5, suggesting an interconnected industrial base rather than reliance on a single employer or sector.
• Attraction whitespace: 8 sub-sectors register LQ < 0.5, candidates for diversification or recruitment depending on labor-market fit.

• In line with national: Home value to income ratio of 4.4x sits near the ~4.1x national average; affordability is neither a clear advantage nor a recruitment friction.
• High home ownership: 82.2% owner-occupied; rental supply may be tight for incoming workers.
• Elevated vacancy: 11.7% vacancy rate. In resort, rural, and seasonal markets much of this is recreational/seasonal (second homes), not available supply; confirm the vacancy-by-reason split before treating it as a redevelopment opportunity.
• Affordable rent tiers: 3 of 5 HUD Fair Market Rent bedroom tiers sit below the 30%-of-median-income affordability threshold (~$3,267/mo).

• Succession risk is real: 24.3% of working-age residents are 55-64. Plan for retirements over the next decade and pair attraction strategy with talent retention.
• Talent pipeline: 6 regional institutions feed the workforce; the top three combined produce 37,099 annual credentials.
