Differential Fertility in Sudan

Abstract

This study has been conducted in three selected areas in Sudan. The selected areas are broadly named the northern, the middle and the west of Sudan. In these three areas the investigated couples are 6085, 6685 and 5734, respectively totaling 18614 couples. The level of fertility in this study was measured by number of ever born children to one mother only. The average fertility levels of mothers in these three areas are [4.05+2.61], [4.46+2.78] and [4.51+2.66], respectively. The observed fertility level was significantly different. Thus it has been decided to use regression models of fertility on different socio-demographic variables observed in three different areas. Also, the fertility level of mothers was experiencing no child mortality [3.56+2.29]. The objectives of the analysis were to investigate the homogeneity of regression parameters in each case and also to investigate the homogeneity of regression lines. Different socio-demographic variables have differential impacts on fertility. The test of regression showed significant regional variations in the behavior of socio-demographic variables. There were 3076 child loss mothers and 15538 who have not loss any of their children. Differential behavior of socio-demographic variables of these two groups of mothers was also observed.
