Imputation (American Census):
The process used to estimate missing or misreported data.
When information is missing or inconsistent, the Census Bureau uses a method called imputation to assign values. Imputation relies on the statistical principle of “homogeneity,” or the tendency of households within a small geographic area to be similar in most characteristics. For example, the value of “rented” is likely to be imputed for a housing unit not reported on owner/renter status in a neighborhood with multi-units or apartments where other respondents reported “rented” on the census questionnaire.

Noted in “Federal court nixes challenge by Byron Donalds, GOP college groups to ’20 Census,” Mitch Perry, Florida Phoenix:
The Republicans alleged that a proper count would have given Florida an additional U.S. House seat and an additional vote in the Electoral College but for the “vast use” of a statistical method known as imputation. However, for the second time in six months, the U.S. District Court for the Middle District of Florida dismissed the case, this time with prejudice, finding that any further amendment to the pleadings “would be futile.”
