Pennsylvania Population 2018
Pennsylvania has a relatively small surface area, but like many states on the eastern edge of the USA, it has a relatively dense population by comparison. It's estimated that Pennsylvania's population has reached over 12.82 million in 2018, a small increase from the 2010 Census figure of 12.7 million. Pennsylvania has a current growth rate of just 0.24%, which ranks 42nd in the nation.
In order to gauge US state populations in 2018, it's important to first look at the last official census figures taken in 2010 and then project forward. At that census, it was confirmed that there were 12,702,379 people living in Pennsylvania and that number represented a 3.4% rise on the numbers declared in 2000. An estimate of the 2018 population shows Pennsylvania has 12.82 million residents, making it the sixth most populous state in the USA.
Pennsylvania is currently the 9th most densely populated state in the country with a density of 283.9 people per square mile. A great deal of the state's population is in Philadelphia and its surrounding areas, as the city has a population of 1.56 million. Far behind in terms of population are Pittsburgh (304.391), Allentown (120,207), Erie (99,475) and Reading (87,879).
Pennsylvania Population History
Pennsylvania was one of the 13 original States. In 1792 the acquisition of the Erie Triangle at its northwest corner brought it to essentially its present boundaries. In 1790 census coverage included all parts of the present State except for the Erie Triangle.
