Connecticut Population Density and Demographics
The population density of Connecticut makes for some very interesting reading. Connecticut has a very small land mass -- just 5,543 square miles (14,357 square kilometers) making this only the 48th largest state in the Union by size.
However, Connecticut crams a significant number of citizens into its surface area. The terrain is very flat, and very few areas of the state are inhospitable. As a result, there are an impressive 738.1 people for every square mile (285 per square kilometer), and this ranks Connecticut at 4th place in terms of population density.
