Contaminated water, undernutrition, sexual assaults, infectious disease outbreaks, depression, and many more health problems are highly prevalent. Children in refugee camps are particularly vulnerable. Consider Refugee Camp X, where public health workers are maintaining high quality data records on the displaced population they serve. On January 1st of 2011 there were 140 children aged 0-‐12 years living in Refugee Camp X. Of these children, 80 had already been diagnosed with undernutrition by January 1st and remined in that category throughout the month. 20 additional children were diagnosed with undernutrition over the course of the month of January. The total population of children 0-‐12 years of age did not change in number over the month of January 2011. In other words, there were no deaths and no new additions to this group.
