Growth spurt: City's population rising, census shows
"Philadelphia has continued to grow since the 2010 census count, according to new data being released Thursday.
The Census Bureau estimates that the city's population on July 1 was 1,536,471, an increase of 10,465 or a 0.7 percent jump from the official census count taken two years ago.
The new estimates show that the city's growth spurt from April 2010 to July 2011 was mainly due to an increase in births.
Philadelphia had an estimated 29,227 births and 18,023 deaths from April 1, 2010, to last July, for a net population increase of about 11,200.
Meanwhile, although the city had an estimated net increase of 6,208 people moving here from outside the United States, it had a net decrease of 6,860 people who moved out of the city to other counties or states within the U.S. That means that overall, the city had a net decrease of about 650 people, based on migration data.
Paul Levy, president and CEO of the Center City District, said young parents are choosing to stay in the city after having babies, particularly in Center City and nearby neighborhoods."
