Dear Sir/Madam,
I pooled IPUMSCPS data from 1996 to 2012 to obtain a large enough sample for my research paper because I am interested in small immigrant groups. I am doing a personlevel analysis, and to avoid double counting I am using the March supplement of 1996, 1998, 2000, 2002, 2004, 2006, 2008, 2010 and 2012.
However, I am a bit confused about how to properly set up the weights for my analysis. I want to produce means/proportions and a regression analysis.
I read that replicate weights were added beginning in 2005, and the code to use the weights is the following:
svyset [iw=wtsupp], sdrweight(repwtp1repwtp160) vce(sdr)
My questions are the following:

Do I have to use the code above for my analysis?

If not, how do I properly set up the weights for analysis?
Thanks in advance for your time and assistance.
