Defining poverty

What is poverty, or how do you know if someone is officially poor or living in poverty. It is hard to define poverty since there are so many different factors that add up too leading someone to that state.
There are 11 standards that you need too fulfill to not be considered to be in "consistent poverty". The 11 necessities are: a warm waterproof overcoat,two pairs of strong shoes, meals with meat, chicken or fish at least every second day, a roast joint or its equivalent once a week, a warm house and the wherewithal to buy presents for family members once a year, have guests over for a drink once a month, and a night out every two weeks. Lack two of the standard necessities on the list, and you're officially poor.
Some of these necessities are considered normal even for really poor people and some like going out every two weeks might not be standard for rich people with a new born baby. However the Irish poverty rate has decreased 6.5 percent with the new system of defining poverty. Yet it is complicated to measure who is poor and what you can't measure you can't debate. However it has been figured out that Canada has much more trouble with defining poverty then Ireland.
