21075 — Elkridge, Maryland

60% of adults hold a four-year degree, higher than 93% of measured US ZIP areas.

Household income is higher than at least 94% of measured US ZIP areas.

Median rent of $2,183 takes 19% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 3.4 times median household income here, above the historic benchmark of about three times income.

Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.

No building-permit activity is published for this location by the Census Building Permits Survey.

7 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 89°F and January a low of 25°F.

Normal annual precipitation is 45.0 inches, including 19.3 inches of snow.

Climate figures are thirty-year normals, not current conditions. They describe what a typical year looks like rather than what the weather is doing today.

The hazards accounting for most of this area's expected annual loss are hurricane, cold wave and drought.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA publishes at county level. ZIP values are the land-area-weighted mean of the counties the ZIP Code Tabulation Area intersects. Expected annual loss is not allocated below county level. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.

AreaProfile does not yet publish tax comparisons. No tax dataset has met the source admission test for coverage, methodology transparency and update cadence, and the product rule is to omit a dimension rather than estimate it. The Area Score is calculated without a tax component and the weighting is documented on the methodology page.

Nothing on AreaProfile is individualized tax advice.

4 major airports lie within 100 miles, the nearest 5 miles away.

Airport identity, position and runway data come from the FAA. “Major airport” is an AreaProfile classification — a public-use civil airport with a paved runway of at least 8,000 feet — not an FAA hub designation. Distances are straight-line, not driving distance.

Some demographic statistics use Census ZIP Code Tabulation Areas, which approximate but do not exactly match USPS ZIP delivery geography. See the methodology for how AreaProfile maps between them.
