This article employs the analytical model of Bongaarts and Potter to compare the proximate determinants of fertility among three populations in Nepal's Kathmandu valley with the following characteristics: (1) high and low caste, (2) urban and urban fringe residence, and (3) users and non-users of contraception. It is shown that while Nepal, as a whole, is firmly entrenched in Phase 1 of the fertility transition, each of the populations studied has begun to experience a demographic transition to different degrees. In fact, greater progress in controlling fertility has been made than previously known.
