Fresh.Data current as of Apr 24, 2026
Dickerson, MD (ZIP 20842) sits in Montgomery County within the Washington-Arlington-Alexandria metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in below the national average at 6.6%. NCES lists 1 schools serving the area, 1 non-charter. 4 colleges and universities serve the area, with median in-state tuition of $5,394. IRS data shows average household income (AGI) of $177,734, well above the ~$45K national average per return. BLS QCEW puts average annual pay at $94,473 per worker — about 44% above the US average and a clear high-wage signal. Social vulnerability is low in this ZIP at the 10th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 27 federal disaster declarations affecting this ZIP since 1971 — a high-frequency exposure profile. Premature-mortality burden is comparatively low at 4,785 years of potential life lost per 100,000 (County Health Rankings, 2025). Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. Maryland levies a graduated state income tax (top rate 5.75%); a household at the local median AGI of $177,734 would pay roughly $6,132/year before deductions. IRS migration data (2022-2023) shows a net loss of 10,119 residents (6,244 households) — the ZIP's primary county is shrinking. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $152,917, fair market rent of $1,690 for a two-bedroom, and a typical home value of $750,464, up 0.9% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

Top health signal: Health Insurance comes in below the national average at 6.6%. NCES lists 1 schools serving the area, 1 non-charter. 4 colleges and universities serve the area, with median in-state tuition of $5,394. IRS data shows average household income (AGI) of $177,734, well above the ~$45K national average per return. BLS QCEW puts average annual pay at $94,473 per worker — about 44% above the US average and a clear high-wage signal. Social vulnerability is low in this ZIP at the 10th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 27 federal disaster declarations affecting this ZIP since 1971 — a high-frequency exposure profile. Premature-mortality burden is comparatively low at 4,785 years of potential life lost per 100,000 (County Health Rankings, 2025). Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence.

IRS migration data (2022-2023) shows a net loss of 10,119 residents (6,244 households) — the ZIP's primary county is shrinking. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $152,917, fair market rent of $1,690 for a two-bedroom, and a typical home value of $750,464, up 0.9% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits lower the national rate at 19.4%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
