In order to reduce fertility rates both in Nairobi and in Kenya at large, the educational levels of both males and females should be increased.This will help wipe out illiteracy which is found to be positively related to fertility. It will also increase the knowledge and awareness about contraception and it will also change attitudes on family size desires. It will also help create employment opportunities. Secondly, child mortality rates should be reduced by providing better health and nutritional services to both mothers and children.This will increase the survival rates of children thus increase the confidence in parents that the children they have will survive, thus desired family sizes will be achieved. Ethnic groups should also be given more formal education in order to change their attitudes on family size and their life-styles.
