See the example below. The first part till end makes some toy data, the
-gen- command creates a variable that is 1 if a person is 5 years or
younger, and the command following creates the sum of this variable
within household id. 

*---------------- begin example ---------------
clear
input hhid age
1 4
1 6
1 8
2 3
2 1
end

gen byte young = age <= 5 if age < .
bys hhid : egen byte num_young = total(young)

list
*------------------ end example ----------------
