Reading the numbers for 20636

The classic rule of thumb keeps rent under 30% of gross income. Here that threshold sits at $43,840 of household income; anything below it means rent is taking more than a comfortable share.

Income and rent both come from the same American Community Survey 5-year release, so they are already expressed in the same dollars and we apply no inflation adjustment on top. The percentile is computed across every ZIP code with at least 5,000 residents.
