New approaches to the measurement of vital rates in developing countries

IT EXAMINES THE ANALYTIC APPROACHES AND DESCRIBES PROJECT GOALS, SAMPLING DESIGN, AND ORGANIZATIONAL ASPECTS OF FIELD OPERATIONS. RESULTS ARE PRESENTED FOR RURAL AND URBAN FERTILITY TRENDS, DIFFERENTIAL FERTILITY AND LEVELS OF MORTALITY AND NATURAL INCREASE. TABLES LIST THE METHODOLOGICAL AND ANALYTIC PROBLEMS POSED BY MIGRATION AND THE RESULTS FROM THE APPLICATION OF THE ALTERNATIVES TO THE DUAL RECORD SYSTEM. A COMPARISON OF THE DIFFERENT TECHNIQUES USING THE SAME SET OF DATA IS DISCUSSED. COST REDUCTION STUDIES CONCLUDE THAT LESS EXPENSIVE DUAL RECORD PROJECTS ARE POSSIBLE AND THAT THESE PROJECTS WILL BE ABLE TO PRODUCE HIGH QUALITY DATA.
