For the first time in a decade, the Jewish Federation of Greater Philadelphia will research and release a population study of the Philadelphia-area Jewish community. Research will begin in the coming months, and the study will be published in 2019.

The population study usually takes place every 10 years by large-city Jewish federations to measure the current state of their Jewish communities, but it is unlike a census, said Kelly Romirowsky, director of grants and evaluation. “It’s … looking for a representative sample to get an estimate of the total population,” as well as its geographic, socioeconomic and other characteristics.
