Operationalization
Subjective income adequacy: closed question: "Do you 
feel that your total family income is enough for you 
and your family to live as comfortably as you would 
like? Would you say very comfortably, comfortably, not 
too comfortably, or not at all comfortably?"

moderate level * adjustment for geographic region *
