Description
For sample adults and sample children, 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. Prior to 2019, INCFAM07ON was asked of all persons.
[show more]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.
Comparability
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. Questionnaire changes introduced in 2019 may affect comparability between 2007-2018 and 2019-forward.
The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. Family-level content is now collected within the sample adult and/or sample child questionnaire. If both the sample adult and sample child are in the same family, family-level content can be collected in either questionnaire. If they are in different families, the family-level content is asked in both questionnaires. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
