💡 How These ZIP Codes Are Ranked

• Median Home Sale Price: Many sources (like PropertyShark’s annual report) rank ZIP codes by the typical sale price of homes — this is a common proxy for “wealthiest.”

• Adjusted Gross Income (IRS Data): Other rankings use IRS AGI data, which can shuffle the order slightly (e.g., some San Francisco financial districts).
