Here are the top wealthiest ZIP codes in Delaware, based on income data (including IRS adjusted gross income and other income measures). Rankings can vary depending on average income, median household income, or per-capita income, but the following list reflects the ZIP codes most often at the top across these metrics: 

 (Primarily based on income and affluence indicators)

  1. 19710 – Montchanin / North Wilmington area (highest per-capita income)

  2. 19807 – Northwestern Wilmington / Greenville area (very high incomes)

  3. 19944 – Fenwick Island (coastal affluent community)

  4. 19732 – Rockland / Pike Creek (top median household income)

  5. 19930 – Bethany Beach (beach resort community with high incomes)

  6. 19707 – Hockessin area (high median household & per-capita income)

  7. 19803 – North Wilmington / Brandywine area (solid affluence metrics)

  9. 19734 – (part of northern New Castle affluent area)

  10. 19971 – Rehoboth Beach area (coastal with strong income figures)

๐Ÿ“Š Notes on Wealth Metrics

  • Per-capita income lists (e.g., 19710, 19807) measure individual earnings and are useful for identifying high-wealth communities.

  • Median household income (e.g., 19732, 19707) reflects how typical households fare, which is often a better measure of local affluence.

  • Beachfront or resort ZIP codes (like 19944, 19930, 19971) often rank high due to a mix of vacation/second homes and local wealth.
