Women who worked solely in agriculture, have higher fertility rates than those who worked in small cottages industries and those who worked for wages. The relationships between fertility and women's multiple job holdings, however, did not appear to be consistent. The relationship between the female labor force participation from all measurements such as total hours worked in all activities and total hours worked in non-farm activity and fertility appeared to be "shape" curves in all cases. However, when wht proxy of female labor force participation in cottage industries, which is the number of years engaged in these industries, was correlated with fertility, the relationship was not clear. The simple relationship between the three dimensions of land (i.e., land size, land quality, and land ownership) and fertility was examined. Lan size was positively, but unclearly, associated with fertility. Land ownership status was shown to have clearly positive association with fertility. Land quality showed no consistent pattern of association with fertility. The relationship between income and fertility also showed no consistent pattern. The simultaneous model representing the total hours worked in all activities and fertility was constructed. A set of exogeneous variables were successful in explaining the variation of fertility. The net family income (+), female labor force participation in all work activities (-), child contributions (+), land quality (-) and land ownership (+) are among important variables. The simultaneous model was created to test the importance of sources of labor force participation by non-farm activities, and fertility. Among the significant variables were the net family income (-), the female labor force participated in non-farm enterprises (-), land size (-), land quality (-), and child contributions (+). These variables are among the exogeneous variables contributing to variation in fertility. An attempt was made to examine the importance of female labor force participation in wage labor and fertility. The results indicated that negative and significant relationships were found with the net family income, female labor force participation, the three dimensions of land, and child contribution, which in turn had consistent positive signs. The hours worked in cottage industries was significant and negatively associated with fertility. However, when the member of years engaged in home industries was used as a proxy of female labor force participation in association with fertility. The performence of the model was improved, however, the signs of many coefficients were ambiguous. The results of all these models indicated the impertance of the effect of women's labor force participation, especially in small cottage industries upon fertility.
