كم يقدر عدد اتباع الاحمدية القيدانية في العالم؟
 the community has been established in 209 countries and territories of the world with concentrations in South Asia, West Africa, East Africa, and Indonesia. The community is a minority Muslim sect in almost every country of the world. In some countries like Pakistan, it is practically illegal to be an Ahmadi Muslim. Together, these factors make it difficult to estimate the Ahmadiyya population for both the community itself as well as independent organizations. For this reason, the community gives a figure of "tens of millions"; however, most independent sources variously estimate the population to be at least 10 to 20 million worldwide, thereby representing around 1% of the world's Muslim population. In 2001, the "World Christian Encyclopedia", estimated that the Ahmadiyya movement was the fastest growing sect within Islam. It is estimated that the country with the largest Ahmadiyya population is Pakistan, with an estimated 4 million Ahmadi Muslims. The population is almost entirely contained in the single, organized and united movement, headed by the Caliph. The other is the Lahore Ahmadiyya Movement, which represents less than 0.2% of the total Ahmadiyya population. Ahmadiyya are estimated to be from 60,000 to 1 million in India.
