ABSTRACT: Survival analysis comprises a set of statistical methods deployed in studying the timing and occurrence of events. This paper studied survival functions with particular reference to Kaplan-Meier (K-M) estimators and Life Tables. Secondary data of In-patients who reported cases of malaria (origin state) to time until death or recovering (censored) was extracted and analyzed using Kaplan-Meir and Life Table functions in SPSS. Through this discourse, we showed how survival probabilities could be obtained and graphed. We inferred from the data provided in this paper that the mean years of life left for a new born child e0 was 61.9 years. The expectation of life was equal to 0.016, which translates to 160 deaths per 100,000 person-years. Again, the number of new born children dying before age twenty (20) was given by l0 - l20 = 100000 - 97127 = 2873. The probability of new born children dying before age twenty (20) years was 0.0287. The population survival curves for the two classes of users of ITN, after adjusting for gender, gave us a p-value of 0.002
