Excerpt from Conference on Census Undercount: Proceedings of the 1980 Conference The 1970 cps-census mato'n study also produced valuable information relating coverage of population and households that was used in planning for 1980. Only about half of all missed persons were omitted because their housing unit was missed. However, nearly three-fourths of blacks omitted were in enumerated housing units. That is, only a small proportion of blacks was missed because their housing unit was missed. The omissions of persons in covered households were largely caused by a combination of such factors as public apathy or indifference, carelessness or confusion in filling out the forms, and deliberate concealment, but we cannot quantify the relative contribution of these factors.
