DMV · ZIP-level
Monthly ZIP-level rent trends from Zillow's rent index. This shows the broader market direction, not live prices for a specific building. Three Census layers add context: median household income, median age, and college attainment by ZIP. See tracked advertised starting prices →
Honest about what this is
Use this map to see whether a ZIP is trending up or down. Use the starting-prices page when you need advertised entry prices for individual apartment buildings. The Income, Median age, and Education layers are Census context about who lives in a ZIP, not a rating of the neighborhood.
How the math works
Month-over-month is the quickest read. Quarter-over-quarter is steadier. Year-over-year is the cleanest long view. All three use the same monthly Zillow rent index. The Census layers work differently: ACS 5-year estimates sorted into quantile bins, with margins of error shown in the ZIP readout.
Where the data comes from
Observed-rent trends from Zillow Observed Rent Index, refreshed when Zillow publishes its monthly research CSVs. The Income, Median age, and Education layers use Census ACS 5-year estimates at ZIP level. ZIP polygons from the US Census Bureau’s TIGER/Line 2020 ZCTA file.
