CENVAR is a component of IMPS (Integrated Microcomputer Processing System), a system for the major tasks in survey and census data processing: data entry, data editing, tabulation, data dissemination, statistical analysis and data capture control which can be used as a complete processing system or stand-alone. IMPS is also available from the Census Bureau.

CENVAR is based on the PC CARP (Cluster Analysis and Regression Package) software originally developed by Iowa State University.
