Resumen
Descripción
A recent study for sub-Saharan Africa by
Banerjee et al. (2007) uses Demographic and Health Surveys
(DHS) from 22 countries that have conducted at least two
such surveys between 1990 and 2005 in order to collect
comparable information across countries on access to modern
and alternative infrastructure services over time. In
addition to national, urban, and rural trends in access, the
study includes a distributional analysis of how access rates
have evolved since 1990. That is, households are divided
into five quintiles of population according to their level
of wealth, with wealth defined using a principal components
analysis. The objective of this note is to provide a summary
of key findings from the study regarding access trends to
electricity, piped water, flush toilets, and landline
telephones over the period 1990-2005.
