About
Life in Greenlawn
This quiet Long Island hamlet offers the kind of stable, family-oriented community where neighbors actually know each other—with a median household income of $164,427 and a median home value around $626,700, you're looking at a solidly affluent suburban environment where roughly 56% of households are married couples and a third have kids under 18. The job market is reasonably healthy with an unemployment rate of 3.4%, though most residents commute out for work (average 35.5 minutes), typically toward Manhattan or other Long Island employment centers, so factor in that daily drive as a real part of life here. What keeps people rooted is the strong sense of place: the community has genuine traditions like the Labor Day Fireman's Fair (running since 1906, the largest in New York) and an annual pickle festival that locals actually care about, plus a median age of 43.6 that reflects families who've stayed put and raised their kids through the well-regarded Harborfields Central School District.
