I have found something like this to be useful:
bys group: tab race
bys group: tab race sex
etc.
bys is shorthand for "by" plus "sort".
Alternatively, you can do something like this:
sum group
scalar min=r(min)
scalar max=r(max)
local i=min
while `i'<=max {
display _newline(2) "group is `i'"
tab race if group==`i'
tab sex if group==`i'
tab race sex if group==`i'
local i=`i'+1
}
Scalar min and max are defined as the min and max of your group variable.
In your case, min is 1 and max is 50. You could have specified them
yourself instead of defining a scalar. The loop goes trough your group
variable and executes commands based for each group i.
I hope that helps.

For example, I want to perform a large set of analyses on a set of groups (group == 1....group == 50). Do I have to continue to type if group == 1 after each command? ex:
