📍 Top 10 Wealthiest ZIP Codes in Massachusetts (2026)

 

Here’s a recent ranking of the top 10 wealthiest ZIP codes in Massachusetts based on a wealth index that combines income, home values, population density, and other socio-economic factors (not just income alone). All of these are within about 10 miles of Boston — showing how concentrated high wealth is in Greater Boston.

1. 02116 – Back Bay (Boston)

2. 02118 – South End (Boston)

3. 02446 – Brookline

4. 02144 – Somerville

7. 02127 – South Boston

8. 02476 – Arlington

9. 02139 – Cambridge

10. 02141 – Cambridge

Notes:

• Back Bay’s 02116 ranked #1 with a median home value of about $1.3 M.

• Some high-income suburbs (e.g., Dover, Weston) didn’t make this particular Top-10 wealth index because the ranking also weighs factors like home values, poverty rates, and population density — not just income alone.

• Other analyses focusing strictly on average adjusted gross income (AGI) list ZIP codes like 02110 (Boston waterfront), 02108 (Beacon Hill), 02493 (Weston), and 02481 (Wellesley Hills) with very high incomes — but those aren’t reflected in this wealth index ranking.
