This study investigated the geographic distribution of suicide and railway suicide in Belgium over 2008--2013 on local (i.e., district or arrondissement) level. There were differences in the regional distribution of suicide and railway suicides in Belgium over the study period. Principal component analysis identified three groups of correlations among population variables and socio-economic indicators, such as population density, unemployment, and age group distribution, on two components that helped explaining the variance of railway suicide at a local (arrondissement) level. This information is of particular importance to prevent suicides in high-risk areas on the Belgian railway network.
本研究调查了2008年至2013年比利时地方（即区或行政区）层面自杀及铁路自杀的地理分布情况。在研究期间，比利时自杀及铁路自杀的区域分布存在差异。主成分分析在两个成分上确定了人口变量与社会经济指标（如人口密度、失业率和年龄组分布）之间的三组相关性，这有助于解释地方（行政区）层面铁路自杀的方差。这些信息对于预防比利时铁路网络高风险地区的自杀行为尤为重要。
