Woops, typo on last line -- replace it with:
gen corrector=N_dpto_el/(proyection*N_dpto_agegp_el)

My excel dataset (proyections) is:
gp Total Men Women
0 10 5 5
1-4 12 4 8
5-9 20 3 17
...................................
95+ 3 0 3
My stata dataset (microsurvey) is:
dpto year_weight e1 e2
1 123 1 13
1 89 1 65
2 54 2 25
...................................
19 152 2 0
19 58 2 39
Where dpto is state, year_weight is annual weight, e1 is 1 if man and
0 if woman, e2 is age and others variables.
Weights are wrong so I want to correct using population proyections
according dpto, sex and age.
I would like to compute a new corrected weight without dissmining observations.
Thanks,
Sebastián.

Why don't include e2 or agegp? Is el equals e1?
nokeep means that I drop observations?
