NHIS Data Alert: Issues with 2015 Cancer Supplement
NCHS discovered errors in the 2015 cancer supplement data. NCHS urges users to delete the file and repeat their analyses with the revised data once they become available. UPDATE: After our initial e-mail to users (sent September 22, 2017), we became aware that NCHS released additional guidance about the scope of the errors in the 2015 cancer supplement file. They have since stated that the only variables that will be revised in the re-released data are in the Cancer Family History section. IPUMS has temporarily suppressed the 2015 Cancer Family History supplement variables. Other variables from the 2015 Cancer Supplement are available through the IPUMS NHIS site. We will add the revised 2015 Cancer Family History supplement variables by the end of the calendar year.
