The 2001 American Religious Identification Survey (ARIS 2001) was designed to replicate, as closely as possible, the methodology used for the 1990 National Survey of Religious Identification (NSRI) which took place under the auspices of the Graduate Center of the City University of New York.  Public access to the dataset, codebook, and methodology for both years is available here by clicking on the following links:
