This paper seeks to advance the global study of religiosity and spirituality by conducting a meta-analysis of major approaches in the field. While the field, and thus the collected publications, are dominated by Western approaches, particular attention is paid in this analysis to publications from geographies that are not from the United States or Western Europe, especially these world regions: Africa, Asia, and Latin America. Similarly, while the study of religiosity is considerably centered around Christianity, this analysis extends beyond Christianity, to the extent possible in extant studies, to include publications investigating other world religious traditions, such as African spirituality, African witchcraft, Afro-Caribbean religious traditions, Buddhism, Confucianism, folk religions, Hinduism, Islam, Judaism, Mormonism, Neo-paganism, New Religious Movements (NRMs), Shamanism, Sikhism, Spiritism, Taoism, and spirituality generally. A total of 530 publications were reviewed, and the studies are categorized by unit of analysis into: Macro, micro, and meso-level. Measurement constructs include religious demography, culture, belonging, behaving, believing, bonding, religious salience, spiritual identities, religious networks, occupations, congregations, denominations, and faith-based organizations. Non-Western sources and approaches are analyzed toward furthering future research in under-studied world regions. Implications are drawn for the field, such as the need to geo-code publications at the country level.
