the world's poor (per capita GNP less than US$500 per year), 84% of those with lowest quality of life (life expectancy, infant mortality, and literacy), the hub of the world's major non-Christian religions (Islam, Buddhism, Hinduism, etc.,) close to 100% of those who were both most-poor and had least-access to Christian resources (two-dimensional analysis) The least Christian resource investment and least sharing of the Christian message The GIS analysis utilized country-level data from the Operation World almanac, the World Christian Encyclopedia, and the World Factbook. Non-Christians in the 10/40 Window by religion The first edition GIS analysis maps highlighted the three major religious blocks in the 10/40 Window, specifically the majority Muslim, Hindu and Buddhist nations. Population estimates at the time for the year 2000 (from Operation World) were given as: 28 Muslim countries, 1.1 billion population est. (2000) 2 Hindu countries, 1.1 billion population est. (2000) 8 Buddhist countries, 237 million population est. (2000) Later updates have been based more on census data and other estimates rather than forward-looking population estimates. The cited reference provides the following estimate of "unreached" non-Christian populations in the 10/40 Window: 865 million Muslims 550 million Hindus 275 million Buddhists 140 million in 2550 tribal groups (mainly animist) 17 million Jews Nations in the 10/40 Window The 10/40 Window originally encompassed the following 54 countries.
