"There are more than 7 billion people in the world, and more than 2.2 billion of them are children. ...More than one billion of those children live in poverty and half of these live in extreme deprivation. They constitute, then, half a billion young people under the age of 18 whose very lives have been truncated and put in daily peril. " - Invisible Children
The silos into which we tend to place these children and young people may satisfy our need for organization, but they hinder our understanding of the interrelated complexities of the issues impacting their lives. Accordingly, numbers cited to quantify the extent of any issue are necessarily inaccurate to some degree. There is, quite simply, too much overlap. Street-connected children who are orphans and working in hazardous labor situations can be triple-counted in these statistics. A young girl who has no access to education and is subsequently sold by her parents to a trafficker can be double-counted. Migrant children can appear on the statistical records of more than one place. This is not, in any way, to minimize the impact of these numbers, for without question and in any evaluation, the numbers are vast. But we do well to understand that, as vast as they are, they may not be pure. We must view their situations not in terms of the numbers they represent but as emanations of the immense personal, human, and societal costs they exact.
