Imputation

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.
