Updates & Errata

Current Dataset Release: January 29, 2019 Version

February 8, 2019

On the initial data release, the variable inputstate has erroneous codes 
for respondents from Colorado and Connecticut. To correct the variable, 
cases coded -1 should be changed to 9 for Colorado and cases coded -7 
should be changed to 8 for Connecticut, and the labels should be updated 
accordingly. The following (SPSS) code will make the corrections.

recode inputstate (-7=8) (-1=9) (else=copy) .
