Codes and Frequencies
For all persons, INCFAM97ON2 provides total grouped family income beginning in 1997, using income brackets introduced in 2007. Responses are reported in nominal dollars and have not been adjusted for inflation.
The 2007 NHIS introduced a recoded income bracket variable to bridge the differences between income brackets from 1997 to 2006 with those from 2007 forward. Individuals whose 1997 to 2006 total family income brackets ranged from "$0 to $4,999" to "$25,000 to $34,999", and those who had incomplete income information but reported that their total family income was "Less than $20,000", are grouped together as "$0 to $34,999." Individuals whose 1997 to 2006 total family income brackets ranged from "$35,000 to $44,999" to "$65,000 to $74,999" are grouped together as "$35,000 to $74,999." See the Codes tab for changes to top-coded income.
Those who had incomplete income information but reported that their total family income was $20,000 or more could not be incorporated into the new scheme and are coded separately.
Data users wishing to use the original income codes for this variable may use INCFAM9706 (Total combined family income, 1997-2006 grouping) and/or INCFAM07ON (Total combined family income, 2007+). See the drop down menu for additional related variables.
