Another possibility might be to use -xcontract- (downloadable from SSC), which abbreviates Joseph's solution, as in

xcontract religion gender age ethnicity, list(, noobs separator(0))

The -xcontract- package can also produce an output dataset (or resultsset) containing the table cells for future use, as in

xcontract religion gender age ethnicity, saving(mycells1, replace)

which creates a Stata dataset (or resultsset) in -mycells1.dta- with 1 observation per table cell. This resultsset can then be processed in any way the user likes, to produce plots and tables.

I hope this helps.

Roger

Joseph Coveney <jcoveney@bigplanet.com> suggested

        . preserve
        . contract religion gender age ethnicity
        . list, noobs separator(0)
        . restore

Anotehr possibility is

        . table age ethnicity gender, by(religion)

-table- produces tabular output, which Lawrence may prefer.  -table-, however,
does not generalize beyond 4-way tables, as Joseph's solution does.
