Infant mortality trends in a rural area of East Pakistan are analyzed utilizing the Bogue pregnancy history technique. The findings indicate that infant mortality has declined slightly over 20 percent between 1958 and 1967. The existence of development programs in women’s education and family planning since 1961 are proposed as possible reasons for this finding. A convergence in infant mortality rates to mothers in the age range 15–39 years was found in the final year under analysis, while the standard U shaped pattern of infant mortality with age structure was exhibited in the previous years. One possible explanation for the convergence is that the development programs are reaching women within this age range more equally than in the past. An alternative explanation relating to the problems of recall of mortality events was discussed.
