Is your dwelling warm enough during the winter months?
Does your dwelling have air-conditioning fitted?
Tell me whether the household or any of its members has a PC

Tell me whether the household can afford:
1. To pay for holidays away from home for at least one week a year
2. To eat red meat, chicken or fish (or the equivalent for vegetarians) at least every other day

1. How to choose the items
2. How to combine items (weightings)
3. How to fix the threshold

8. There is a certain degree of arbitrariness in the three choices.

1 How meaningful they are across the country
2 How long should they be kept?
