Certainly I would include the social. I'm not sure what the spiritual means, but my bias is that we are social animals. Even Adam Smith, the economist, said that poverty is the inability to walk in public in a linen shirt. I think that's the quote.
I've written many reports on poverty measurement. The word “dignity” pops up over and over again. Amartya Sen, a Nobel Prize-winning economist, talked about the capacity to participate in your society in a life that you value.
I'm a mathematician by training, forgive me, so I want to talk about measurement. Yes, we have the LICOs and the LIMs. The only thing you need to know about a family to know whether it is poor using LIMs is its income, either before tax or after tax, compared to a threshold, and the family size. You don't know the number of disability issues. It's an arbitrary measure, but no more arbitrary than the unemployment rate: Did you look for work this week or this month?
