Percentage of a variable depending on different income bins

I'm trying to find out depending on the variation of income what percentage of a particular income bin can afford one/multiple/no health providers? Here, I''ve created the income bins like the following way:

Code:

gen inc10=(income2==1)
    gen inc15=(income2==2)
    gen inc20=(income2==3)
    gen inc25=(income2==4)
    gen inc35=(income2==5)
    gen inc50=(income2==6)
    gen inc75=(income2==7)
    gen inc75p=(income2==8)

[CODE]

This the different value of one person having the access to single/mutiple health/no providers . How can I find the percentage of people having access to the healthcare providers ( single /multiple ) given the different income bins ?

Code:

qui gen one_hcare_provider = (persdoc2==1)
    qui gen multi_hcare_provider = (persdoc2==2)
    qui gen no_hcare_provider = (persdoc2==3)

Code:
