I would like to know how I could execute STATA commands in order to count for each household, the number of household members who present specific characteristics.

Indeed, I use individual-based household survey database which can be presented as follows:
hh_id indiv_id disabled disabled_hh
01 011 1 0
01 012 1 0
02 021 2 1
03 031 2 4
03 032 2 4
03 033 2 4
03 034 2 4
03 035 1 4
04 041 1 0
04 042 1 0
05 051 2 1
06 061 2 3
06 062 2 3
06 063 2 3
07 071 1 0
08 081 1 2
08 082 1 2
08 083 2 2
08 084 2 2
09 091 1 0
10 101 1 1
10 102 2 1
10 103 1 1
11 111 2 1
hh_id = Household id
indiv_id = Household member (individual) id
disabled = no (1) or yes (2)
disabled_hh = number of disabled in each household


Which STATA commands can help to compute the disabled_hh column when considering information about 11 000 households?


Thanks in advance for your availability.
