Abstract:
|
Background:International Rescue Committee (IRC) surveyed two Afghan refugee camps in Pakistan before and after humanitarian aid. The objective of the project was to compare U5 mortality (P[Life ? 5 years]) at baseline (2007) and endline (2010). Method: Nonparametric maximum likelihood and least squares were used to estimate survivor functions from current status data, because some ages at deaths were inadmissable. The Kaplan-Meier reliability estimator was used on admissable ages at deaths. Conclusion: Survivor function estimates from current status and admissible ages at deaths agreed tolerably. The U5 estimates were 10% at baseline and 4% at endline. Pakistan U5 was 8.7% in 2009 (Wikipedia). Infant mortality at age one was almost 4% at baseline and endline. Pakistan infant mortality was 6.7% in 2010 (World Bank).
