First, we need to recognize that the overall response to the crisis takes place on many fronts. We are working in Lebanon, Jordan, inside Syria, as well as in Iraq, so it is difficult to give you a detailed response that would cover the whole humanitarian response.
But in each context we try to look at some of the key indicators that would clarify which people and which groups are the most vulnerable. Typically, some can be direct indicators, such as health indicators that are quantifiable and objective. In some cases you use proxy indicators to get an understanding of the particular vulnerability of particular groups. For example, in Dohuk you will find that there are people who are living in an encamped situation, in which case it's relatively straightforward in terms of trying to develop your programming in response to everybody. But you also have large numbers—I would say the greatest numbers—who are settling in cities in improvised situations throughout the more secure areas. In those cases we'll look, for example, at those who are unable to rent accommodation but are finding refuge in abandoned buildings, in school buildings, and that sort of thing. That would be a key indicator in terms of vulnerability.
The other issue of course is that we are looking at families where the head of household is a woman or in some cases children. These are all indicators that we would use. There is usually quite an exhaustive list of questions and indicators that we would go through in each context, trying to make sure that the assistance we have and that we are allocating is targeting those most vulnerable.
