Spatial distributions of geographically weighted regression (GWR) coefficients (A) and crude rate (B) of each determinant of male suicide mortality rates in South Korea (2021). Notes: Character A indicates the spatially varying effect (GWR coefficient) of the determinant, only denoting the coefficients with statistical significance (local t-value > |1.96|) which were divided into classes using Jenks natural breaks classification method. B indicates the amount of distributed factor across regions, which were divided into quintiles. Each determinant is designated as a number: aging index, 1; percentage of single-person households (%), 2; psychiatric clinics and hospitals per 100,000 people, 3; unmet medical needs (%), 4
