IMPORTANT NOTES:
* Geographic data for Cycle 1 are missing and unavailable.
** Cycle 5 also has geographic data based on where respondents were living at the time of the 1993 National Health Interview Survey. The available geographic variables for 1993 are the same as what is available in Cycle 5 for residence at the time of the previous Census.
*** Tract and block group are available when using the 2011-2015 and/or 2015-2019 paradata files. For more information on those paradata files see this webpage https://www.cdc.gov/nchs/nsfg/nsfg_special_supplementary_data.htm
