Método modificado de muestreo por conglomerados para la evaluación rápida de necesidades después de un desastre

Abstract

The cluster-sampling method can be used to conduct rapid assessment of health and other needs in communities affected by natural disasters. Modelled after WHO's Expanded Programme on Immunization method of estimating immunization coverage, the method has been modified to provide (1) estimates of the population remaining in an area, and (2) estimates of the number of people in the post-disaster area with specific needs. This approach differs from that used previously in other disasters where rapid needs assessments only estimated the proportion of the population with specific needs. We proposed a modified n x k survey design to estimate the remaining population, severity of damage, the proportion and number of people with specific needs, the number of damaged or destroyed and remaining housing units, and the changes in these estimates over a period of time as part of the survey.
