This review of Nigerian population and family planning surveys is the first in a series intended to assist social scientists and program personnel in identifying research that can be used in program planning. Twenty-five studies have been selected from a comprehensive bibliography on population and family planning in Nigeria. The selection was based on three criteria - coverage of research topics, validity of scientific approach, and practical implications. The types of survey under review, some of the problems encountered in the search for information and the methodologies adopted for national, urban and rural and other types of survey are described. An analysis of findings related to specific population and family planning topics is followed by some recommendations. Much of this information is also presented in tabular form, enabling the reader to identify surveys according to methodology and content. The opinions expressed are those of the authors. A background to the review is provided by notes on the historical development and financing of research in Nigeria, with lists of recent research topics and the researchers involved. (Author/RH)
