Design effect interpretation

[kmel56]

Hello,

I'am using the Surveyfreq procedure to get design effect of my proportions, but i have a problem with deisgn effects interpretation, see the result below :

                          DEFF

ALL                      1.32

Women                 0.7

Men                      0.7

my sampling design is a one stage clustering design, so i understand having the 1.32 (>1) but why the deff is so smaller for men an women?

Can you help me please?

Are you using the RATE= or TOTAL= option?  It would be useful to see your syntax. The way that SURVEYFREQ estimates the design effect is documented as follows:

SAS/STAT(R) 9.3 User's Guide

Thanks Rick,

But the problem was away, I didn't include the weighting factor, now with weights it much better.

The lesson here is "always include your program when you ask a question."

Yes, Sorry, my question was incomplete.

THanks.
