This Record will only exist for respondents with one or more payments recorded at question F1, (i.e. where INF1 is greater than 0). For each payment identified at question F1 (i.e. in variables IF101 - IF159) then there will exist at least one IINCOME record with a corresponding value of IFICODE.
In those cases where payments from multiple sources were combined in a single payments and individual receipts could not be distinguished, IINCOME records will exist for each source, but the variables INFR or IFRVAL may indicate that multiple amounts are referred to, or that the amount is given on another record.
IFIM01L - IFIM01N are derived variables indicating the estimated amount received in each month, taking into account joint receipt and changes in welfare benefit levels. These calculations depend on the variable IFRJTVF, which is a flag variable identifying whether a reported jointly received payment can be matched to any other persons payment.
The following variables have all missing data imputed:
See the User Documentation for a full discussion of imputation. Imputation flag variables are listed below. Note that a value is not imputed where the missing value code is -3 'amount included elsewhere'.
