Abstract

The number of children ever born to a particular woman is a measure of her lifetime fertility experience up to the moment at which the data are collected. Fertility is one of the key determinants of population growth and pattern and is essential for planning and achieving sustainable development. This paper attempts to identify the socioeconomic and demographic determinants of number of children ever born (CEB) to women of age 15-49 years using 2007 Botswana Family Health Survey-IV (2007 BFHS IV) data. Poisson regression model is explored to study the impact of potential regressors on fertility. The results indicate that the women living in cities/towns and urban villages had 11.2% and 6.8% lower fertility than women living in rural area; as expected percentage of number of kids was consistently decreasing with decrease of age groups. Women in the age group 45-49 have the higher number of kids than any other lower age groups. Mother’s education negatively affects the average number of children ever born to a woman; women with married status have the highest fertility, with 21.7% more kids than women with never married status. Non-working mothers have more number of children ever born than the working mothers and mothers who watch television at least once a week have lower by 9.9% kids who do not watch television at all. Women/her partner who were currently using condom had a lower fertility by 8.1% compared to those who have never used. On the above findings we recommend that more emphasis is needed on women’s literacy which may take care of other social and economic indicators.
