Use PUMS data for PUMAS belonging only in one county
Galateia

Hello! I try to use PUMS 5yr 2008-2012 data and I face a strange fact that when I sum the weights (variable PWGTP in the dataset) for the PUMAS that belong to a specific County, I do not take as a result the known total population in this county (compared to the population from ACS 2008-2012 estimates)...
Could anyone advise me if I use the given weights properly? The PUMS data are for PUMAS in one whole state and I try to extract only the PUMAS in the county that I need. Is it possible or there is problem because the PUMS data are defined at a state level?

Tim has a good point. It may be (and in fact is likely) that the actual PUMA boundaries changed between 2000 and 2010, so simply creating one field may not be sufficient.
The county was likely defined by one set of PUMAs in 2000 and one set in 2010. So for the records that have a PUMA00, you'd need to select based on the PUMA numbers for that county in 2000, and for records with a PUMA10 you'd need to select the PUMA numbers for that county based on the re-numbered PUMAs in 2010.
