LBW infants are at risk not only due to neonatal complications but also by other risk factors (eg. congenital anomalies associated with LBW). This research is motivated by the high incidence of LBW in Tasikmalaya City Hospital each year. The purpose of the study was to determine the relationship between demographic factors in this case the mother's age, maternal education level, socio-economic level with the incidence of LBW. The research hypothesis has a relationship between maternal age, maternal education level, socioeconomic level, pregnancy with LBW incidence. The benefits of research provide a basis for evidencebased practice to nursing practitioners, that there is a relationship between demographic factors (maternal age, education level and socioeconomic level) with the incidence of LBW. Quantitative research method was used with cross sectional approach. The data was processed using univariate and bivariate analysis. The results of the study show no significant relationship between the factors of maternal age, education level, socioeconomic level with the incidence of LBW in Tasikmalaya City Hospital with p value > 0.05 for all variables. From the present study it is suggested that nurses should improve health education so that people can understand better about the risk of LBW.
