A recent study for sub-Saharan Africa byBanerjee et al. (2007) uses Demographic and Health Surveys(DHS) from 22 countries that have conducted at least twosuch surveys between 1990 and 2005 in order to collectcomparable information across countries on access to modernand alternative infrastructure services over time. Inaddition to national, urban, and rural trends in access, thestudy includes a distributional analysis of how access rateshave evolved since 1990. That is, households are dividedinto five quintiles of population according to their levelof wealth, with wealth defined using a principal componentsanalysis. The objective of this note is to provide a summaryof key findings from the study regarding access trends toelectricity, piped water, flush toilets, and landlinetelephones over the period 1990-2005.
