ABSTRACT : Population growth in the region is due to several factors, fertility, mortality and migration and needs to be balanced for the welfare of the community which is the goal of the country’s development. The population problem that occurs in almost all developing countries experiences it, the problem of fertility which increases every year. Therefore it is necessary to suppress fertility by controlling the population. Population growth is too fast and is not match by the quality of human resources and the provision of adequate facilities. As a result, population growth becomes a burden for development. This study aims to analyze the factors that influence contraceptive use on the number of children born alive. Data collection was carried out by observation, structured interviews and in-depth interviews. The sampling technique used purposive sampling method with a sample of 123 respondents. The data obtained were analyzed using descriptive analysis techniques and path analysis. The results of the study found that the variable education (X1), income (X2), husband’s support (X3) had a positive and significant effect on the duration of contraceptive use (Y1), the education variable (X1), income (X2), husband’s support (X3), and duration of use of contraception (Y1) has a negative and significant effect on the number of children born alive (Y2), and the
variable length of use of contraception (Y1) is a variable that fully mediates the relationship between education
(X1), income (X2), husband’s support (X3 ) to the number of children born alive (Y2)
