Operation World is a comprehensive reference work that provides country-by-country statistical, demographic, and prayer-oriented profiles related to global Christianity, missionary activity, and religious demographics. Compiled and edited by authors including Patrick Johnstone and Jason Mandryk, the work is used by churches, mission agency staff, researchers at Oxford Centre for Mission Studies-adjacent institutions, and practitioners associated with organizations such as World Evangelical Alliance, Compassion International, and Youth With A Mission. It aims to inform prayer, strategy, and resource allocation across national contexts like India, Nigeria, China, Brazil, and United States.

Overview

Operation World presents systematic profiles for nearly every internationally recognized sovereign state and many territories, linking demographic data and evangelical priorities with lists of major denominations, prominent mission groups, and influential local institutions. Each country entry integrates statistics from international organizations such as the United Nations, World Bank, and United Nations Educational, Scientific and Cultural Organization alongside denominational reports from bodies like the Catholic Church and the Assemblies of God. The book caters to subscribers from networks including Lausanne Movement, Global Church Network, and various national Bible Society chapters, and is also used by academic centers such as the Center for the Study of Global Christianity.

History and Development

The first edition appeared in the 1970s, compiled amid the growth of evangelical mission networks that included leaders from International Fellowship of Evangelical Students and activists connected to the Billy Graham Evangelistic Association. Subsequent editions were shaped by collaboration with researchers linked to All Nations Christian College and strategists from the Evangelical Alliance. Key revisions reflected major geopolitical shifts such as the end of the Cold War, the expansion of the European Union, and demographic transitions in regions like Sub-Saharan Africa and Southeast Asia. Contributors have included researchers with ties to institutions like Trinity Evangelical Divinity School and missionary historians associated with the Institute of World Christianity.

Content and Structure

Entries follow a consistent format: overview, statistical snapshot, major cities, religious profile, missionary presence, prayer points, and recommended further reading. Statistical snapshots draw on datasets maintained by the United Nations Population Division, Pew Research Center, and the International Organization for Migration, while religious mapping references work by scholars from the Pew Forum on Religion and Public Life and research centers such as the Center for the Study of Global Christianity. The book names denominations like the Orthodox Church, Seventh-day Adventist Church, and Methodist Church where relevant, and lists mission agencies active in-country, including Samaritan's Purse, Wycliffe Bible Translators, and Open Doors. Maps and charts sometimes reference cartographic standards used by the Royal Geographical Society.

Impact and Reception

The publication has influenced strategic planning among ministries such as World Vision, International Mission Board, and national church bodies including the Church of England and the Roman Catholic Church in specific contexts. Academics in fields tied to the Center for the Study of Global Christianity and journals like International Bulletin of Mission Research have cited it as a practitioner resource, while some scholars associated with Harvard Divinity School and University of Oxford have critiqued aspects of its categorization. Non-governmental organizations, including Red Cross-affiliated faith initiatives and development partners like Save the Children, have also used its country briefs to inform culturally aware engagement. Reviews have appeared in publications linked to Christianity Today and denominational periodicals from groups such as the Baptist World Alliance.

Editions and Translations

Multiple editions have been released, including expanded print editions and digital updates coordinated with publishers such as IVP and Paternoster Press. Later editions saw contributions from researchers connected to Missions Advanced Research networks and partnerships with global ministries like Frontiers and Evangelical Fellowship of Tanzania for localized feedback. The work has been translated or adapted into other languages for use by organizations in Brazil (Portuguese), Spain (Spanish), parts of Francophone Africa (French), and some East Asian contexts, facilitated by partnerships with national Bible Society branches and regional missionary consortia.

Methodology and Data Sources

The editors synthesize quantitative indicators from international agencies such as the United Nations, World Bank, and UNESCO with denominational returns from bodies like the Catholic Church's statistical yearbook and data from evangelical networks including the World Evangelical Alliance and the Lausanne Movement. Field reports and primary-source inputs come from national churches, mission agencies including Wycliffe Bible Translators and Operation Mobilisation, and regional research centers such as the African Institute for Contemporary Missions. Methodological notes outline use of census materials, survey research from institutions like the Pew Research Center, migration statistics from the International Organization for Migration, and conflict impact assessments referencing agencies such as International Crisis Group. Editors acknowledge limitations where data are sparse, including countries with restricted access such as North Korea and volatile states in parts of Middle East and Central Africa.
