Population of Philadelphia City and County since the Foundation, Estimated and Returned.

[The census of 1777 was taken by order of Sir William Howe, when the British army was in possession of the city. At that time many Whigs and patriots were absent, and it is estimated that the population in the same year before the entry of the British was about 30,000.]
