Means with different base in a loop

foreach var in Punjab age_cat Division District2 {
preserve

drop `var'

save "$table/`var'.dta", replace

use "$table/punjab.dta", clear
erase "$table/punjab.dta"
foreach var in age_cat Division District2 {
append using "$table/`var'.dta"

export excel using "$table/Total_population3.xls", firstrow(variables) replace
save "$table/Total_population3.dta", replace


n_sex_total is the total population and sex_total is the total population in 100 0 form for the calculation of mean n_total_sex_m is the total males population percent_sex_m is the males population in 100 0 form for the calculation of mean of males population in any category to total males while total_sex_m is in 100 0 form to calculate mean of total males population to total population and n_sex_f is the total female population and sex_f is in 100 0 form to calculate mean of sex_f with respect to total population. but this loop is not giving me the desired results as it is giving me 100 percentage when i calculate percent_sex_m and sex_f. kindly any suggestion for improvement of this loop so that i can find my desired results.

here is the picture of the i want to calculate using above loop after creations of all required variables.
