Complex Analysis Plan for PUMS using SPSS?

I think your challenge is not so much one with ACS as of what's included in the base package of the software. It is my understanding that SPSS treats weights as frequency weights unless you have an extension package (e.g. Complex Samples package) installed. (See: www.ats.ucla.edu/.../weights.htm)

That said, the Census Bureau wrote code for an older version of SAS that does the replicate weight processing step by step (rather than the newer jackknife command). Read: usa.ipums.org/.../repwt.shtml

There's a link toward the bottom, "Estimating ASEC Variances with Replicate Weights" that contains the code (usa.ipums.org/.../Use_of_the_Public_Use_Replicate_Weight_File_final_PR.doc).
You may be able to re-work that code for SPSS.
(Note: When I opened the document, the SAS code was gibberish, but changing the text format to Arial fixed the problem.)

Let me know if that helps!

Thanks for these ideas, Beth. I will check them out and let you know how things progress. JG

To the best of my knowledge, SPSS Complex Samples still does not support replicate weights which are required for the analysis of PUMS data (successive difference replication). May be you can write your own macro to do this, but it will be still be confusing to the students.

Any of Stata, R, SAS or even WesVar can be used for the task (or at least tricked with specification of BRR or jackknife weights). Unfortunately, SPSS is out of the league... as the web was pointing out to you.
