```Thanks. David. I also looked at that, as I have a variable called zallemps, which is the total employment on the payroll at the establishment. But when I tried both forms of denominator I got

. gen ratioprtwrk=(zmalprta+zfemprta) / (zallemps)
(40 missing values generated)
. su ratioprtwrk
Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
ratioprtwrk |     22411    .0631298    .1019029   .0002026         .8

. gen ratioprtwrk=(zmalprta+zfemprta) / ((zmalfulla+zfemfulla+zmalprta+zfemprta))
(40 missing values generated)
. su ratioprtwrk
Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
ratioprtwrk |     22411    .5385854    .0624591   .3333333   .6666667

I am pondering as to why there is a difference.

Thanks

I would add, that you may want to look, instead at the ratio...

(zmalprt+zfemprt) / (zmalfull+zfemfull+zmalprt+zfemprt)
that is, the proportion that part-time work represents as compared to
the total work.  But that's something you need to decide as a
substantive matter.
