A number of challenges confront researchers attempting to devise accurate estimates of the state/regional and national Jewish population. The US census, the only full population count of the country, does not ask Americans to identify themselves by religion.

The studies in the socio-demography project employ innovative research methods and rigorous scientific analysis to arrive at these estimates and better understand religious, family, and ethnic identity in the United States.

National Population Studies

The American Jewish Population Project is an interactive website that uses cutting-edge methods to map the Jewish population in the United States. The project, developed by the Steinhardt Social Research Institute housed at CMJS, is intended to allow comparative analyses nationally and locally, as well as over time.  

Community Population Studies

The Steinhardt Social Research Institute works with local residents and leaders to design and implement studies most appropriate for that community's particular needs. Community studies have focused on population characteristics and estimates as well as economic need.
