The Bureau of Labor Statistics does not publish labor-force data for ZIP areas. This is the figure for Olney, MD, the city containing this ZIP code.
56% of students met the state standard in mathematics and 66% in reading, across the schools here that reported results. Math proficiency and 1 other measure here are published for Olney, MD, which contains 20833, rather than for 20833 alone.

Housing & affordability
How it’s calculated — housing affordability →Prices for everything a household buys run about 10% above the national average — the Bureau of Economic Analysis index reads 109.5, against 100 for the nation. Nationally, housing drives most of the spread between places in this index; other goods vary far less.
The Federal Housing Finance Agency’s house price index for the Frederick-Gaithersburg-Bethesda, MD Metropolitan Division is up 29% over five years, and up 1.3% over the last year. It follows repeat sales of the same homes, so it measures price change rather than which homes happened to sell.
Homeowners here who pay a tax bill pay a median of $6,787 a year in real estate taxes, about 0.85% of the median home value.
HUD’s Fair Market Rent for a two-bedroom, set near the 40th percentile of recent new leases, is $2,530, some 22% above the $2,074 tenants already here pay.
At HUD’s Fair Market Rent of $2,530 a month for a two-bedroom, keeping rent to 30% of income takes a household income of about $101,200 a year, about 50% of the median household income here of $204,375.
The typical renter household here spends 50% of its income on rent, above the 30% threshold at which a household is considered cost-burdened. Median gross rent runs $2,074 a month.
A median home at $797,100 costs 3.7 times the median income of its owner-occupied households, $215,625, above the historic benchmark of about 3 times income.
Prices here run about 10% above the national average. The spread between places is driven mostly by housing — goods vary far less — and this excludes taxes.
Published for the Washington-Arlington-Alexandria, DC-VA-MD-WV Metro Area as a whole. Prices are regional — people shop, commute and rent across a metropolitan area rather than within a city boundary — so this describes the cost of living around this place better than a figure drawn to its own limits would.

Growth & development
How it’s calculated — growth →Development Momentum
An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.
71% of the 2,601 units permitted over the past twelve months are in buildings of five or more homes, so new supply is concentrated in apartments and condominiums rather than detached houses. The multifamily share is published for Olney, MD, which contains 20833, rather than for 20833 alone.
At 2.4 permitted units per 1,000 residents, building activity is below the median for measured US ZIP areas. The permit rate is published for Olney, MD, which contains 20833, rather than for 20833 alone.

Air quality
A comfortable median and a bad tail are different problems. Wildfire smoke and summer ozone show up in the worst tenth of days, not in the middle of the year.
Climate figures are thirty-year normals, not current conditions. Air quality is measured by EPA monitors and published by county only where a monitor sits; a county without one shows nothing rather than an estimate, and a county reading is still the county’s. How to read climate and air quality.
Physical risk
The hazards accounting for most of this area's expected annual loss are inland flooding, hurricane and heat wave, with inland flooding alone responsible for 56% of it. Inland flooding and heat wave are independently rated low or minimal nationally, so this describes how the loss is composed, not how large those hazards are.
Overall hazard risk is lower than 86% of measured US ZIP areas.
Low or minimal exposure: winter weather, heat wave, strong wind, hail, inland flooding, earthquake, tornado, ice storm, wildfire, coastal flooding, avalanche, tsunami, volcanic activity.
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.
These are deaths, not offenses — they say nothing about burglary, theft or assault.
Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides, so the firearm figure and the homicide figure above it count some of the same deaths twice over. They overlap and should not be added together.
Death rates are crude rates — deaths divided by population, not adjusted for age — except where a count was too small for the CDC to publish and it modeled the rate, which the card marks. They come from provisional death certificate records, published by the CDC by county and not below it. So they describe the county around 20833 (Montgomery County) rather than 20833 itself. They are shown and not scored. How to read death rates.
What this profile does not cover
Each of these is absent for a reason, not by oversight. The Area Score is calculated without them; the weighting is on the methodology page.
- Reported crime
- Offenses reported to police are published by department rather than by town, so AreaProfile shows a rate only on city profiles, and only where that city’s department submitted every month of a year. A ZIP area is not a jurisdiction, so no department reports for one. Olney carries the figure where its department reported a full year. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.
- Taxes
- Income and sales taxes are not published: no source covers them nationally with a method open enough to check. Property taxes are shown in the housing section but are not part of the score. The cost-of-living index above is a price level for all consumption, not a household budget, and it excludes taxes. Nothing here is individualized tax advice.
- Anything about a specific address
- Every figure describes an area, not a street or a house.

20833 vs Olney
How this ZIP area compares with Olney as a whole. Both figures come from the same ACS release, so the comparison is like for like — a gap here is a real difference between the two places, not two surveys disagreeing.
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.
