Administrative records are currently used for postcensal estimates: for example, the Census Bureau relies on vital statistics information, including records on marriages and divorce, to estimate the household structure in the years after a census.


The March CPS collects information about household composition, demographics, and sources and amounts of income received for a nationally representative sample of about 60,000 households. The SIPP does the same for a sample of about 20,000 households and has much more extensive information about federal taxes.
