Philadelphia has seen a big increase in the number of immigrants living, working, and raising families in the city over the past several decades. In 1990, less than 7 percent of Philadelphians were foreign-born, but in the most recent U.S. Census Bureau data, the percentage was twice as high. As highlighted in Pew’s 2018 report “Philadelphia’s Immigrants,” more than a quarter of Philadelphians are immigrants or have a foreign-born parent. These changes have had a profound impact on the city and are largely responsible for the growth it has experienced since 2006.
