UH_ZERNWK_A2 is a 4-digit numeric variable with values between 1 and 1923.
0 = Not coded
Original March - weekly earnings before deductions - 1989
Unicon Corporation made the following notes about this variable:
For hourly workers, subject to top coding, the higher of either the amount of ernush times ernhr or the actual item zernwk will be present. For 1981 we assume the universe is the same as for 1982 and 1983, but as ernpdh is all zeros in 1981, this cannot be proven. WARNING: The Census bureau says 1981 through 1983 earner study variables are unreliable, but were never corrected with an update tape. Use at your own risk! See discussion of earnings variables in Appendix R. See ernwk as an alternative.
- Those eligible for the earner study (ernel =1).
