Nalesta Pilgrim:
The test in -svy: tab- (like the chi square test in -tabulate twoway- is a test of independence, not a test of equality of proportions. (And, with -svy-, the distribution of the test is not Chi Square, but that is a different matter.)
You are apparently mixing up the chi square test with the test for equality of means in one-way ANOVA. It's more analogous to a test for interactions in ANOVA.
We need an example of what you want to do. Start with this code and point out proportions you wish to test for equality.

Dear Statalist,
I'm wondering if there is a test command for categorical variables
with survey data.
With continuous variables, you can run the test command:
. svy: mean testresult, over(childage)
. test [testresult]1=[testresult]2
For categorical variables, you run:
svy: tab wealth province
My question: how can I test which wealth category is significantly
different from another wealth category if the overall test result
indicates there is a significant difference but all the confidence
intervals overlap?
Thanks!
Nandy
