The Center for the Study of Global Christianity is an academic research center that monitors worldwide demographic trends in Christianity, including outreach and mission. We provide a comprehensive collection of information on the past, present, and future of Christianity in every country of the world. Our data and publications help churches, mission agencies, and non-governmental organizations (NGOs) to be more strategic, thoughtful, and sensitive to local contexts.

More specifically, the Center

  • Educates the public on global Christianity by serving as a resource to both secular and religious media outlets, including The New York Times, The Economist, National Geographic, and Christianity Today.
  • Helps churches, mission agencies, and non-profits maximize their effectiveness by measuring Christian outreach and evangelization efforts (such as Bible translation, media, and missionary presence) among the world’s peoples and languages. 

In addition, the Center

  • Advocates for solidarity between Christians of different traditions by working on joint projects with the Boston Theological Institute, which includes Catholic, Orthodox, and Protestant theological schools.
  • Maintains and makes available to researchers a collection of materials on global Christianity and world religions, including a 12,000-volume library and more than 1 million printed documents (such as newspaper and magazines articles, scholarly publications, census reports, and correspondence).

  • Offers graduate-level classes at Gordon-Conwell Theological Seminary and Boston University School of Theology on global Christianity and on issues related to social justice, including advocating for religious freedom and encouraging wisdom in international development.

  • Provides opportunities for students through research internships, seminars, and study abroad opportunities, such as a study abroad trip to Uzbekistan focused on religions on the Silk Road.
