Living Costs and Food Survey
2008: VOLUME A, PART 4
Background
Imputation of missing information
Although LCF response is generally based on complete households responding, there are areas in the survey for
which missing information is imputed. This falls into two broad categories:
(i) Specific items of information missing from a response. These missing values are imputed on a case by case
basis using other information collected in the interview. The procedure is used, for example, for council tax
payments and for interest received on savings.
(ii) Imputation of a complete diary case. Where a response is missing a diary from a household member, this
information is imputed using information from respondents with similar characteristics.
