AN EXPLORATORY DEMOGRAPHIC STUDY OF THE NUPE OF NIGER STATE: THE CASE OF SAKPE VILLAGE by Abubakar Katcha Thesis submitted in partial fulfilment for the Degree of Master of Arts in Demography in the Australian National University Canberra, January 1978 ACKNOWLEDGEMENTS I wish to express my profound thanks to Dr. D.W. Lucas, my supervisor, for the keen interest shown in the study as well as the guidance he has given me so kindly. It is with a sense of deepest gratitude that I acknowledge the encouragement given me by Professor J.C. Caldwell who also placed at my disposal some of his papers on Nigeria. I also wish to thank Dr. P.F. McDonald and Dr. S.K. Jain for sparing some of their valuable time to attend to some of the problems posed in the course of the study. I sincerely appreciate the help of Mr. 1.0. Orubuloye who made valuable comments and suggestions on specific points. Mrs. B. Ballard went through the draft and practically other staff and colleagues of the Department of Demography gave real help of one type or another. I am grateful to all of them. Secretarial assistance by Mrs. P. Ashman is very gratefully acknowledged. I also wish to thank Ms. N. Chin who expertly typed the thesis. Finally, it is a pleasure to express my gratitude to my wife, Fatima, who later joined me thereby making my last stay in Australia so interesting. iii ABSTRACT This pioneer survey, conducted in Sakpe Village in April 1977, obtained data on the basic demographic characteristics of a selected typical Nupe Village. Sakpe village is situated in a remote forest area of Niger State in the North of Nigeria and is predominantly a traditional Moslem, farming community. The village lacks basic socio-economic amenities like pipe-borne water and preventive health services. Prior to this study, little was known about the demographic characteristics of the Nupe people. The only available demographic information was based largely on the Nigerian population censuses and there is no sound basis for estimating demographic parameters from the results of these censuses which have often been defective and unreliable. Thus, the Sakpe study is an attempt to fill the gap in the existing knowledge on the demography of the Nupe people. In this respect, the study has succeeded in deriving various demographic measures such as the Crude Birth Rate, Age-Specific Fertility Rates and Mortality Rates. Related demographic factors such as marriage and breast-feeding practices were examined and basic household data were also collected. Despite the many original contributions of the study, the small number of cases preclude further detailed analysis. iv TABLE OF CONTENTS ACKNOWLEDGEMENTS...................... ii ABSTRACT .................................................... iii LIST OF TABLES .............................................. vi LIST OF FIGURES ................................................ viii CHAPTER 1.

In February, 1976, the Federation of Nigeria was divided into nineteen states and Niger State, which was based on former Niger Province less Zuru, was one of the ten states in the northern part of Nigeria. The Nupe homelands are now within the present Etswan, Gbako and Lavun Local Government Council Areas of Niger State and the Lafiagi-Pategi Divisions of Kwara State. The Nupe population numbers over half a million according to the 1963 Census of Nigeria [Nigeria: Federal Office of Statistics (F.O.S.), 1963] . This represents about one-half of the total population of Niger State which the 1963 Census put at 1,271,767. Prior to this study of Sakpe little was known about the demo graphic characteristics of the Nupe tribe, for until now the only available demographic information was based largely on the Nigerian population censuses.
