Tharshini,

First of all, I recommend getting SIPP data from the NBER SIPP repository, which has Stata do/dct files ready-made so you don't accidentally mess up the first step of importing the data:

http://www.nber.org/data/sipp.html

Second of all, you do need to use weights. The weight variable at the person level is WPFINWGT. You can apply the weight as a probability weight using summarize or tabulate, or you can sum the weight variable itself over the group you're interested in to obtain a rough estimate.

Best,
Jimmy

Hi statalist,

Have someone worked with the SIPP = U.S Survey of Income and Program Participation, Topical Module wave 3 year 2008

I have few questions concerning the data. When you work with the SIPP, do I have to take into account the weighting procedure when I want to calculate indicators. 

Ex: I want to calculate the nr of people and the percentage of working age who are employed and are included in a retirement plan offered on their job and not through the social security. 

If anyone who can provide me with their knowledge to understand the SIPP data set, I would be more than happy.

Thanks in advance !
