What the numbers say about Connecticut

Connecticut covers 0.1% of the area of the United States and ranks 29th of 51 by population, against 48th by area.
It would take 745 states and districts the size of Connecticut to cover the United States.
Connecticut holds 1.1% of the 331.4 million people that Wikidata’s 2020 figures give for the 51 states and districts together: about 1 in 92.
The largest, Alaska, is 118× the size of Connecticut; the smallest, Washington, D.C., is 1.3% of it.
Closest in size within the United States: Hawaii (16,800 km², 1.33×) and New Jersey (19,700 km², 1.55×).
Counted as a country, Connecticut would be larger than 79 of the 239 countries and territories listed on sizeversus, and would rank 161st by area, between Montenegro (13,700 km²) and the Bahamas (12,600 km²).
With 3.6 million people it would rank 133rd of 238 by population.
Connecticut has 284 people per km², about the density of the United Kingdom, which has 276 per km².
That makes Connecticut the 5th most densely populated of the 51 states and districts, 8.10× the average for the United States (35 per km²).
On a standard web map (Web Mercator), a place at 42°N is drawn about 1.8× too large in area, so Connecticut looks bigger there than it is.
Laid out flat, Connecticut stretches about 117 km north to south and 161 km east to west.
Our measured 12,700 km² is 12% below Wikidata's official figure of 14,400 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.
