I use the definitions of poverty set out by people who are experts at doing just that
err, no you don't , because there isn't one agreed by experts, and many of the ones used for statistics are measures of relative poverty, and you don't seem to understand whatthat means.
Supposing you are the governor of a street with 100 houses, and you have £100 for poverty relief every week, and you have to decide how to spend it. Strangely, in your street, the households are numbered in order of income, with the household at no 1 having the lowest, up to 100, the richest. So roughly, according to the government stats, the families 50% below the median are households 1-25, so you give them £4 each to help out. ( we are imagining the make up and outgoings of each household is identical.)
Now supposing households 81-100 move out. Nothing else changes. According to the government, households 21-25 are no longer poor! Because this is relative measure, and what these people actually have is not relevant at all, to the calculation. so households 1-20 get £5 each that week
now suppose house number 81 gets a new resident, who is twice as rich as the last richest resident in the street. Households 1-40 could now be poor. Nothing has changes at all for those people, and the definition of poverty has not changed either.
That resident didn't stay long, and we are back to households 1-80, with households 1-20 called poor. They all work at different grades in the same factory, and the company has just struck commercial gold, and decides to put everyone's wages up. They double the wages of everyone in the street. According to the relative definition of poverty, households 1-20 are still poor. Next, they multiply everyone's wages by 10, household number 1 is now as rich as the shortlived resident at no. 81.
However, according to this classification, households 1-20 are still poor. I am exaggerating, to make it clearer, just to make it clear that the relative measures of poverty give statistics, but do not in any way define poverty, so saying this is the definition you use, does not in fact have any meaning.
The question was what would YOU call poor, but no need to answer if you don't want to.
and in any case, NONE of this has much relevance to neglect.
