What the numbers say about Pennsylvania

Pennsylvania covers 1.3% of the area of the United States and ranks 5th of 51 by population, against 33rd by area.
It would take 79.3 states and districts the size of Pennsylvania to cover the United States.
Pennsylvania holds 3.9% of the 331.4 million people that Wikidata’s 2020 figures give for the 51 states and districts together: about 1 in 25.
The largest, Alaska, is 12.6× the size of Pennsylvania; the smallest, Washington, D.C., is 0.1% of it.
Closest in size within the United States: Louisiana (120,000 km², 1.00×) and Ohio (116,000 km², 1.03×).
Counted as a country, Pennsylvania would be larger than 138 of the 239 countries and territories listed on sizeversus, and would rank 102nd by area, between Malawi (119,000 km²) and Benin (116,000 km²).
With 13.0 million people it would rank 78th of 238 by population.
Pennsylvania has 109 people per km², about the density of Turkey, which has 109 per km².
That makes Pennsylvania the 10th most densely populated of the 51 states and districts, 3.11× the average for the United States (35 per km²).
On a standard web map (Web Mercator), a place at 41°N is drawn about 1.8× too large in area, so Pennsylvania looks bigger there than it is.
Laid out flat, Pennsylvania stretches about 313 km north to south and 493 km east to west.
Wikidata's official figure of 119,000 km² agrees with our measured area of 119,000 km², to within 2%.

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.
