The International Energy Agency’s World Energy Outlook first constructed a database on electrification rates for WEO-2002. We have updated this database once again for WEO-2013, showing detailed data on urban and rural electrification. 

The general paucity of data on electricity access means that it must be gathered through a combination of sources, including: IEA energy statistics; a network of contacts spanning governments, multilateral development banks and country-level representatives of various international organisations; and, other publicly available statistics, such as US Agency for International Development (USAID) supported DHS survey data, the World Bank’s Living Standards Measurement Surveys (LSMS), the UN Economic Commission for Latin America and the Caribbean’s (ECLAC) statistical publications, and data from national statistics agencies. In the small number of cases where no data could be provided through these channels other sources were used. If electricity access data for 2011 was not available, data for the latest available year was used.

国际能源署的世界能源展望最早建立的电气化率WEO-2002的数据库。我们再次更新该数据库WEO-2013，呈现出城市和农村电气化的详细数据。 
数据的电力接入普遍缺乏意味着它必须通过源的组合，包括收集：国际能源署（IEA）能源统计;联系人跨越政府，多边开发银行和各国际组织的国家一级代表组成的网络;和其他可公开获得的统计数据，如美国国际开发署（USAID）支持的美国国土安全部的调查数据，世界银行生活水平测量调查（LSMS），联合国经济委员会，拉丁美洲和加勒比地区（拉加经委会）统计出版物，并从国家统计机构的数据。在少数没有数据可以通过这些渠道等资源被用于提供病例。如果2011年电力访问数据不可用，最近一年的数据使用。
