Perfectae Caritatis §19

¹⁹ When the question of founding new religious communities arises, their necessity or at least the many useful services they promise must be seriously weighed. Otherwise communities may be needlessly brought into being which are useless or which lack sufficient resources. Particularly in those areas where churches have recently established, those forms of religious life should be promoted and developed which take into account the genius and way of life of the inhabitants and the customs and conditions of the regions.
