Sources of support.
(B) Sources of support. The fact that an organization meets the requirement of paragraph (f)(3)(i) of this section through support from governmental units or directly or indirectly from a representative number of persons, rather than receiving almost all of its support from the members of a single family, will be considered evidence of an organization being publicly supported. In determining what is a representative number of persons, consideration will be given to the type of organization involved, the length of time it has been in existence, and whether it limits its activities to a particular community or region or to a special field which can be expected to appeal to a limited number of persons.
