Socioeconomic stratification by wealth ranking : is it valid?
This article is based on a study in Bangladesh in which both wealth ranking and household surveys were employed to measure household economic status. The study revealed that wealth ranking is a valid means of stratifying households according to socio-economic status. However, the article points to certain factors which may affect its reliability which need further investigation, such as the number, age and gender of key informants, the quality of facilitation and also the question as to how many households a group of key informants can reasonably classify.
