CANCEIS (CANadian Census Edit and Imputation System) is a generalized Edit and Imputation (E&I) system that was used early in 2002 to process the demographic variables from the 2001 Canadian Census on PCs. Later in 2002, it will perform E&I on the labour, mobility, place of work and mode of transport variables as well. It performs minimum change nearest neighbour imputation on a mixture of qualitative and quantitative variables. It is written in the C programming language and is highly efficient computationally. CANCEIS (or an earlier version of the software) will be used to process some of the variables in the 2001 Ukraine Census, the 2000 Brazilian Census and the 2001 Swiss Census. In addition, the 2001 Italian Census, having studied CANCEIS, will use a similar approach in their imputation methodology.
