What the numbers say about Maryland

Maryland covers 0.3% of the area of the United States and ranks 18th of 51 by population, against 42nd by area.
It would take 372 states and districts the size of Maryland to cover the United States.
Maryland holds 1.9% of the 331.4 million people that Wikidata’s 2020 figures give for the 51 states and districts together: about 1 in 54.
The largest, Alaska, is 59.1× the size of Maryland; the smallest, Washington, D.C., is 0.6% of it.
Closest in size within the United States: Vermont (24,600 km², 1.03×) and New Hampshire (24,300 km², 1.05×).
Counted as a country, Maryland would be larger than 92 of the 239 countries and territories listed on sizeversus, and would rank 148th by area, between Equatorial Guinea (26,700 km²) and North Macedonia (25,400 km²).
With 6.2 million people it would rank 111th of 238 by population.
Maryland has 243 people per km², about the density of Jamaica, which has 245 per km².
That makes Maryland the 6th most densely populated of the 51 states and districts, 6.93× the average for the United States (35 per km²).
On a standard web map (Web Mercator), a place at 39°N is drawn about 1.7× too large in area, so Maryland looks bigger there than it is.
Laid out flat, Maryland stretches about 202 km north to south and 384 km east to west.
Our measured 25,500 km² is 21% below Wikidata's official figure of 32,100 km². Official figures can include inland water or count land that an outline draws differently. This difference is flagged for review.

Outline: Natural Earth, 1:10m Admin 1 - States, Provinces, public domain
Boundary: De facto, as drawn by Natural Earth.
Area: Measured on the WGS84 ellipsoid from the full-detail outline, shown rounded. The region’s whole area is counted, every island included.
Official figures: Area, population and capital from Wikidata (CC0), fetched 2026-11-12
Population: Wikidata, 2020. United States’s units share the 2020 figures where Wikidata has them; the year is shown wherever the figure is.
Matching: Countries come from Natural Earth’s country file. Places whose status is contested and dependencies are never used as automatic matches. A region under 2,500 km² is matched against the small countries and island nations.
