Contains Imputed data. As this is a variable directly associated with a question, the imputation flag (here IFRVALI) takes the missing value code of the original variable (e.g. Don’t know, refuse, etc.) if imputed, and 0 if not imputed, or -8 if the variable was inapplicable.

Note

Calculates estimated personal income from income source referred to on current record received in month of September 1998. In many cases the variable is simply the amount received converted to a monthly rate. For details of exceptions, see Appendix to Vol. A. Contains Imputed data. As this is a variable directly associated with a question, the imputation flag (here IFIMnnL) takes the missing value code of the original variable (e.g. Don’t know, refuse, etc.) if imputed, and 0 if not imputed, or -8 if the variable was inapplicable. See notes on Imputation in Vol. A.

To alleviate inconsistencies in reporting of income receipts between HH members, variable (a recomputation of IFRJT) is coded: value 1 = current payment is not matched to any other with complete information about payment amounts, value 2 = it is matched to another, where either both have complete information or both are missing information, and value 3 = the current record has missing information, but is matched to a record with complete information.
