Essequibo Islands-West Demerara has the highest share of Muslims with nearly 12% of its population being part of the "Ummah", followed by East Berbice-Corentyne with 10% and Mahaica-Berbice with 9%. Ahmadiyya Muslim Community The first Ahmadiyya missionary to Guyana arrived in 1908. A community was established in the country in the 1960s and has several mosques across the country including Georgetown, Rosignol, New Amsterdam and Sisters Village. This reform movement, founded in India in the late nineteenth century, also has converts of the Afro-Guyanese community. Interfaith cooperation According to Guyanese-American professor Raymond Chickrie, Hindus and Muslims in Guyana have always had "a cordial relationship among themselves. It would seem that these two groups had come to a mutual understanding of respecting each other's space while culturally and even linguistically identifying with each other." Among the Indo-Guyanese community, there is a tacit agreement to refrain from proselytizing between Muslims and Hindus. Hindi is popular among Indo-Guyanese Muslims who watch films and listen to music from Bollywood. Political antagonism between Indo-Guyanese Muslims and Hindus is non-existent, in contrast to India or other Indian diasporic communities such as Fiji. Intermarriage is perceived as a "tolerated deviance" rather than facing outright condemnation. In smaller villages, Hindus and Muslims come together to participate in each other's ceremonies. Organizations Central Islamic Organization of Guyana The Central Islamic Organization of Guyana (CIOG) is the Largest Islamic group in Guyana. They are involved in relief work and orphan sponsorships. Guyana Islamic Trust The Guyana Islamic Trust (GIT) is a multi-faceted, nonprofit organization which has been established since 1978. The GIT has dedicated itself to the process of bringing about intellectual, moral and spiritual improvement to individuals, families and communities in Guyana. Their goal is education, since they believe "ignorance is the root cause of the intolerance, racism, immorality and criminality that pervades our society and our world." The Guyana Islamic Trust manages its grass root work through fourteen Administrative Districts. Some of GIT's works include organizing classes, social activities, and youth programs, as well as partnering with Jamaats, and da’wah to Non-Muslims. The National Islamic Sisters Association (NISA) is the women's arm of the GIT and focuses on women's faith-based and social needs.
