title: Methods for estimating missing data on migrants in the 1991 British census.
abstract: "This paper discusses the use of suppression to protect data in the Special Migration Statistics, a dataset produced from the 1991 [British] Census, and argues that this procedure prevents accurate analysis of the data. A computer program is described that uses a series of methods to ¿recover' data which were suppressed, and to estimate those parts of the data which cannot be recovered.... The program has been used to recover and estimate data successfully, and results include sample tables of migrants between types of districts by ethnicity."
