The "10/40 Window" is a term coined by Christian missionary strategist and Partners International CEO Luis Bush in 1990 to refer to those regions of the eastern hemisphere, plus the European and African part of the western hemisphere, located between 10 and 40 degrees north of the equator, a general area that was purported to have the highest level of socioeconomic challenges [1] [2] and least access to the Christian message and Christian resources [lower-alpha 1] [3] [4] on the planet.
The concept behind the 10/40 Window highlights these three elements (as of data available in 1990): an area of the world with great poverty and low quality of life, combined with lack of access to Christian resources and unreached non-Christians. The Window forms a band encompassing Saharan and Northern Africa, as well as almost all of Asia (West Asia, Central Asia, South Asia, East Asia and much of Southeast Asia). Roughly two-thirds of the world population lived in the 10/40 Window, and it is predominantly Muslim, Hindu, Buddhist, animist, Jewish, or atheist. Many governments in the 10/40 Window are officially or unofficially opposed to Christian missionary work of any kind within their borders. [1] [3] [4]
This region of the world was previously known to Christians as the "resistant belt", as noted by Luis Bush at the 1989 Lausanne II Conference in Manila. [5] In 1990, Bush's research led to a meeting with Pete Holzmann, a leader of the team developing the first PC-based GIS software. [6] [7] They analyzed the region using a box between 10 and 40 degrees north latitude and called it the 10/40 box. A few weeks later, Bush and his wife Doris were inspired to rename it the 10/40 Window, stating that this region ought to be seen as a "window of opportunity".[ citation needed ] The analysis and concept was a generalization that focuses on a region, not a sharp boundary defining what is a priority, and what is not. For this reason, many missiologists prefer to use the phrase 10/40 Window region.
Before being called the "resistant belt", the Islamic portions of this region, as well as selected unreached Buddhist and Hindu areas, were referred to as the "unoccupied fields" by Samuel Zwemer, in his book by that same title, published in 1911. [8] [9]
Some researchers have objected to such a broad-brush term which seems to imply a unifying characteristic of the 10/40 Window when in fact no large area of the planet is completely homogenous in cultural attributes.
The 1990 research data states:
This research deals in overall population characteristics. The 10/40 Window is a term that helps people visualize the general area of the analysis, where the above characteristics are generally true, but with exceptions proving it is only a generalization. Some examples of the exceptions:
To address these concerns the list of 10/40 countries has been amended in recent years to omit Greece, Portugal and the Philippines.
Over the years, the 10/40 Window has evolved from a specialist term used by Christian missiologists to assumed vocabulary for Christians in the West. [15] [16] [17] It is an emerging term in the secular press [6] and can be found in press style glossaries. [18] Non-western writers and organizations also refer to the 10/40 Window. [19] [20] [21] In addition, those opposed to the idea of evangelism make use of the term. [22] [23] [24]
The original 1990 GIS 10/40 Window analysis produced several insights, among them showing that the nations of the 10/40 Window represented (as of the research date):
The GIS analysis utilized country-level data from the Operation World [3] almanac, the World Christian Encyclopedia, [4] and the World Factbook. [1]
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:
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:
The 10/40 Window originally encompassed the following 54 countries.
These were all Old World nations (mostly in the eastern hemisphere) with at least 50 percent of their land area falling within 10 to 40 degrees latitude as of 1990. (The list also included Gibraltar and Macau, which are not independent nations.)
Cartography is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.
A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database, however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.
Environmental Systems Research Institute, Inc., doing business as Esri, is an American multinational geographic information system (GIS) software company headquartered in Redlands, California. It is best known for its ArcGIS products. With a 40% market share, Esri is the world's leading supplier of GIS software, web GIS and geodatabase management applications.
A cartogram is a thematic map of a set of features, in which their geographic size is altered to be directly proportional to a selected variable, such as travel time, population, or Gross National Product. Geographic space itself is thus warped, sometimes extremely, in order to visualize the distribution of the variable. It is one of the most abstract types of map; in fact, some forms may more properly be called diagrams. They are primarily used to display emphasis and for analysis as nomographs.
Waldo Rudolph Tobler was an American-Swiss geographer and cartographer. Tobler is regarded as one of the most influential geographers and cartographers of the late 20th century and early 21st century. He is most well known for coining what has come to be referred to as Tobler's first law of geography. He also coined what has come to be referred to as Tobler's second law of geography.
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important. The GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures.
Spatial network analysis software packages are analytic software used to prepare graph-based analysis of spatial networks. They stem from research fields in transportation, architecture, and urban planning. The earliest examples of such software include the work of Garrison (1962), Kansky (1963), Levin (1964), Harary (1969), Rittel (1967), Tabor (1970) and others in the 1960s and 70s. Specific packages address their domain-specific needs, including TransCAD for transportation, GIS for planning and geography, and Axman for Space syntax researchers.
ArcGIS is a family of client, server and online geographic information system (GIS) software developed and maintained by Esri.

Web mapping or an online mapping is the process of using, creating, and distributing maps on the World Wide Web, usually through the use of Web geographic information systems. A web map or an online map is both served and consumed, thus, web mapping is more than just web cartography, it is a service where consumers may choose what the map will show.
Traditional knowledge geographic information systems (GIS) are the data, techniques, and technologies designed to document and utilize local knowledges in communities around the world. Traditional knowledge is information that encompasses the experiences of a particular culture or society. Traditional knowledge GIS differ from ordinary cognitive maps in that they express environmental and spiritual relationships among real and conceptual entities. This toolset focuses on cultural preservation, land rights disputes, natural resource management, and economic development.
Geography is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Cartographic generalization, or map generalization, includes all changes in a map that are made when one derives a smaller-scale map from a larger-scale map or map data. It is a core part of cartographic design. Whether done manually by a cartographer or by a computer or set of algorithms, generalization seeks to abstract spatial information at a high level of detail to information that can be rendered on a map at a lower level of detail.
The Joshua Project is an evangelical Christian organization based in Colorado Springs, United States, which seeks to coordinate the work of missionary organizations to track the ethnic groups of the world with the fewest followers of evangelical Christianity. To do so, it maintains ethnologic data to support Christian missions. It also tracks the evangelism efforts among 17,446 people groups worldwide—a people group being "the largest group within which the Gospel can spread as a church planting movement," according to the project's website—to identify people groups as of yet unreached by Christian evangelism.
Anglican Frontier Missions is an American-based Christian mission organization that "To plant biblically-based, indigenous churches where the church is not, among the 2 billion people and 6,000+ unreached people groups still waiting to hear the Gospel for the very first time."

In Christianity, an unreached people group refers to an ethnic group without an indigenous, self-propagating Christian church movement. Any ethnic or ethnolinguistic nation without enough Christians to evangelize the rest of the nation is an "unreached people group". It is a missiological term used by Evangelical Protestants. The Lausanne Committee for World Evangelization defines a people group as "the largest group within which the gospel can spread as a church planting movement without encountering barriers of understanding or acceptance." "Nation" is sometimes used interchangeably for "people group". The term is sometimes applied to ethnic groups in which less than 2% of the population is Evangelical Protestant Christian, Including nations where other forms of Christianity are prevalent such as Western Catholicism, Eastern Christianity or Lutheranism.
Counter-mapping is creating maps that challenge "dominant power structures, to further seemingly progressive goals". Counter-mapping is used in multiple disciplines to reclaim colonized territory. Counter-maps are prolific in indigenous cultures, "counter-mapping may reify, reinforce, and extend settler boundaries even as it seeks to challenge dominant mapping practices; and still, counter-mapping may simultaneously create conditions of possibility for decolonial ways of representing space and place." The term came into use in the United States when Nancy Peluso used it in 1995 to describe the commissioning of maps by forest users in Kalimantan, Indonesia, to contest government maps of forest areas that undermined indigenous interests. The resultant counter-hegemonic maps strengthen forest users' resource claims. There are numerous expressions closely related to counter-mapping: ethnocartography, alternative cartography, mapping-back, counter-hegemonic mapping, deep mapping and public participatory mapping. Moreover, the terms: critical cartography, subversive cartography, bio-regional mapping, and remapping are sometimes used interchangeably with counter-mapping, but in practice encompass much more.
Technical geography is the branch of geography that involves using, studying, and creating tools to obtain, analyze, interpret, understand, and communicate spatial information.
Internet GIS, or Internet geographic information system (GIS), is a term that refers to a broad set of technologies and applications that employ the Internet to access, analyze, visualize, and distribute spatial data. Internet GIS is an outgrowth of traditional GIS, and represents a shift from conducting GIS on an individual computer to working with remotely distributed data and functions. Two major issues in GIS are accessing and distributing spatial data and GIS outputs. Internet GIS helps to solve that problem by allowing users to access vast databases impossible to store on a single desktop computer, and by allowing rapid dissemination of both maps and raw data to others. These methods include both file sharing and email. This has enabled the general public to participate in map creation and make use of GIS technology.
