Abstract

Early marriage of women under 17 years old is a social problem that affects education, health, and community welfare. This study aims to analyze differences in socioeconomic characteristics related to early marriage between East Java and Central Java Provinces using a multivariate approach. Secondary data from 2022 obtained from the Central Bureau of Statistics covers 73 districts/cities with variables including the percentage of early marriage (X1), mean years of schooling (X2), and poverty percentage (X3). Analysis was conducted using Hotelling's T² test, preceded by Mardia's multivariate normality test and Box's M covariance matrix homogeneity test. Assumption testing results confirmed that the data met multivariate normality and covariance matrix homogeneity requirements. The Hotelling's T² test revealed no significant multivariate difference between the two provinces (T² = 7.1221; p-value = 0.084). Follow-up t-tests on each variable also showed no significant differences. These findings indicate that the socioeconomic characteristics related to early marriage in East Java and Central Java exhibit relatively similar patterns. Therefore, early marriage prevention strategies in both provinces can be designed using comparable approaches, while still considering local variations at the district/city level. Keywords: early marriage, Hotelling's T², multivariate, socioeconomic, Java.
