IEA-Electricity Access Database
From Open Energy Information
"In a continuing effort to improve our understanding of the electrification process, we have updated, for the fifth time, the database on electrification rates that we first built for WEO-2002. The database shows detailed data on urban and rural electrification collected from industry, national surveys and international sources. Based on this updated analysis, we estimate that in 2009 the number of people without access to electricity was 1.3 billion or almost 20% of the world’s population. "
