This document contains a final regulation relating to the list of items of return information disclosed to the Bureau of the Census (Bureau). The regulation adds two items of return information for use in producing demographic statistics programs, including the Bureau's Small Area Income and Poverty Estimates (SAIPE). The final regulation also removes four items that the Bureau has indicated are no longer necessary. This regulation facilitates the assistance of the IRS to the Bureau in its statistics programs and requires no action by taxpayers and has no effect on their tax liabilities.
