Objectives The purpose of this study is to analyze the educational needs of J-do adult literacy education officials according to the size of the region so that adult literacy education policies and continuous and effective projects can be established according to the characteristics of the region. Methods This study analyzed the survey contents of 150 officials in charge of literacy education at J-do Adult Literature Education Institute. Education needs were measured on a Likert 5-point scale for 16 variables using the survey tool for adult literacy education support policies developed by Heo Jun, Lee Ji-hye, and Gil Hye-ji (2020). Data processing used the SPSS 26.0 statistical package to derive the priority of adult literacy education needs by regional size through the corresponding sample t-test, Borich demand, and The Locus for Focus model analysis. Results First, in regions with a population of 100,000 or more, Borich's demand priority analysis and The Locus for Focus Model analysis revealed the actualization of instructor fees, budget for literacy education institutions, learner support (education costs, counseling, etc.), expansion of literacy education facilities, and short-range learning opportunities. Second, in areas with a population of more than 50,000 and less than 100,000, variables were derived to secure facilities dedicated to literacy education and to provide learning opportunities for short-range literacy education. Third, in areas with a population of less than 50,000, the budget for operating literacy education institutions, expanding literacy education contents, supporting learners (education expenses, counseling, etc.), promoting literacy education, and event variables were derived. Conclusions As a result of analyzing the needs of adult literacy education by regional size, J-do found that none of the 16 variables appeared in common. The highest priority was “realization of instructor fees” in areas with a population of 100,000 or more, “secure facilities dedicated to literacy education” in areas with a population of 50,000 or more, and “budget for operating literacy education institutions” in areas with a population of less than 50,000. If the results of educational demand analysis vary depending on the size of the region, the policy promotion must also vary by region, so it is necessary to analyze educational needs according to regional characteristics to promote adult literacy education policies suitable for regional characteristics.
