Hi, I tried to construct unemployment rate from CPS. I calcualted the ratio between weighted sum of people who are unemployed (empstat > =20 & empstat < 30) over weighted sum of people who are in laborforce (labforce=2, or empstat>=10 & empstat <30 tried both) . It turns out that the unemployment rate I calcluated is different from the one reported by bureau of labor statistics. The difference is 0.5-1 point higher in most cases.
I am not sure how this happens.
Thanks a lot for your help in advance.
