This thesis has used some techniques from mathematical demography to create thirteen projections of the Bangladesh female population at 5-year intervals from 1966 through 2026. Mathematical data gathered in Bangladesh by the Census Commission, Statistical Survey Research Unit (now Institute of Statistical Research and Training), Dacca University and by the Pakistan Institute of Development Economics (now Bangladesh Institute of Development Economics) was used. Details of the projections and findings are discussed.Bangladesh has an approximate population of 71,300,000. The biggest obstacle to rapid economic betterment is ran-a-way population growth. Social consequences of such growth are briefly considered.
