For all persons, INCFAM07ON provides total grouped family income using an income bracket methodology introduced in 2007. Responses are reported in nominal dollars and have not been adjusted for inflation.


Starting with the 2007 NHIS, the income amount follow-up questions that had been in place since 1997 were replaced with a series of unfolding bracket questions. The unfolding bracket method asked a series of closed-ended income range questions (e.g., "Is it less than $50,000?") if the respondent did not provide an answer to the exact income amount question. The closed-ended income range questions were constructed so that each successive question establishes a smaller range for the amount of the family's income.


This variable is comparable from 2007 to 2013. In 2014, the category $50,000 and over (no further detail) is no longer offered. Additionally, beginning in 2014, households that were not able to be coded to the available categories were assigned a value of Undefined. Other than these changes in category availability, the variable is comparable over time.
