IDHS 2017 showed the prevalence of LBW infants in Indonesia is 7%. LBW can increase the risk of mortality, morbidity, and growth disorders. The survival of LBW infants can be influenced by socio-economic factors. The purpose of this study is to analyze survival time differences of LBW infants based on socio-economic factors. This research is a non-reactive study using secondary data from the IDHS 2017. Survival analysis using the Kaplan Meier method and analysis of differences in survival curves using the Log Rank method. The independent variables in the study include parents' occupation, household wealth index, mother's education, and father's education. The measured event is infant mortality within one year. Mother's education (p-value = 0.069) have no difference in the survival time of LBW. Parent's occupation (p-value = 0.013) has a difference in the survival time of LBW. Probability of survival is 99% in LBW with non-working mother. There is a difference in the survival time of LBW based on the household wealth index factor (p-value = 0.000) with the probability of survival for LBW born in the lowest wealth index family is 90%. Differences in the survival time of LBW has been found in the parents' occupation and household wealth index variables
