Clinic-based distribution of contraceptive commodities is expensive per unit distributed. This situation has fueled the search for alternative means of delivery. Comparing the performance of alternatives is straightforward if the output measure is a count of commodities distributed, but comparing actual fertility impacts is another matter. I use data from the 1991 Indonesia Demographic and Health Survey to assess the extent of difference among the eventual fertility outcomes of users supplied with similar commodities through varying sources. When the “modern” methods of pill, IUD, and injection are grouped together, the fertility of users supplied with these commodities differs markedly according to their source of supply. I find little evidence for self-selecting of users into supply channels. This result implies that fertility differentials by source are likely due to characteristics of the distribution channels.
