Two compliments: 
First to Tyler for posing an interesting problem (and one I have faced) and second to Martin for posting a very nice solution (that I hadn't figured out).
Well done Both!

" I just realized my ranges are labels"



No big deal, just -decode- the thing beforehand:


***********
clear*

set obs 3
gen byte hhh_age=_n

la def ages 1 "15-19" 2 "20-24" 3 "25-39" 
la val hhh_age ages

decode hhh_age, gen(newhhh_age)

split newhhh_age, gen(age) parse(-) destring
rename age1 age_min
rename age2 age_max

list, noo
***********


HTH
