Hi,

I am looking for stata's command in order to group many variables into
one. Let's say we have: roads, water , electricity, and we want to
group them into one variable: infrastructures.
could someone help me with the command?

thanks

Does -egen- with the group function do what you want? e.g.

. webuse nhanes2f, clear
. egen grp = group(sex race), label
. tab1 grp

-> tabulation of grp

   group(sex |
       race) |      Freq.     Percent        Cum.

  Male White |      4,306       41.66       41.66
  Male Black |        500        4.84       46.49
  Male Other |        103        1.00       47.49
Female White |      4,745       45.90       93.39
