According to David Barrett et al, editors of the "World Christian Encyclopedia: A comparative survey of churches and religions - AD 30 to 2200," there are 19 major world religions which are subdivided into a total of 270 large religious groups, and many smaller ones. Most people in the world follow one of the religions listed in the table below. Included is the name of the religion, the approximate date of its origin, its main sacred or ethical texts (if any) and its estimated numerical strength (both in absolute numbers and as a percentage of the world's population.)

These data are based on census or public opinion data. Thus, a person is considered to be of a particular religion if they say that they are of that faith. 

Statistics of the world's religions are only very rough approximations.
