Note To alleviate inconsistencies in reporting of income receipts between HH members, variable (a recomputation of NFRJT) 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.
