Thank you very much, MP Ruimy.
If you use, for instance, a material deprivation indicator to assess whether people are able to meet their necessities of life or not, you're able to take into account indirectly that living costs might be very different from one place to another. We're not actually trying to correct for it in our measure, but we're focusing on the outcomes that are associated with poverty-level living conditions.
As a researcher, if I want to see which groups we need to target with our policy, I'd be uncomfortable just focusing on low income as a measure of figuring out which group I need to focus on, so I'll study further what their problems are. If I include people who have issues in terms of material deprivation, of course, that's not where it ends. We have to look further. Why is it that they can't do it? Is that because of housing affordability, is that because of higher needs, or one of other causes? We need to search further.
I would say, by using a range of indicators, you're making sure that you have a better idea of what your potential target group is, and then you can figure out what their issues are and how to address them in the policy sense.
