Public Data Files in Excel and CSV Formats

The file naming convention for the primary NAWS files in Excel and CSV begins with "NAWS", followed by a separator, "_", three letters, and the number "197", which conveys interview cycles 1 through 97.

The file “NAWS_A2E197” contains the created and questionnaire variables in alphabetical order from "A" through "E" covering the period 1989 through 2020 (corresponding to interview cycles 1 through 97). Likewise, the file "NAWS_F2Y197" contains the created and questionnaire variables in alphabetical order from "F" through "Y" covering the period 1989 through 2020. Both files contain a unique respondent identifier (FWID), the fiscal year during which the data were collected (FY), and the weight variable (PWTYCRD).

Data from the supplemental questions on work duration, hygiene, and clothes laundering practices that ETA administered for EPA in fiscal years 2013 and 2014 are in the file “NAWS_EPA_2013_2014”. Data from the supplemental questions on occupational mental health that ETA administered for NIOSH in fiscal years 2009 and 2010 are in the file “NAWS_NIOSH_2009_2010”.

Each file contains the variable FWID, a unique identifier for each observation in the file. Users can merge files on this variable.
