An ecological study was carried out using information zones as units of analysis in order to assess the evolution of socio-spatial inequalities in mortality due to external causes and homicides in Salvador, Bahia State, Brazil, in 2000 and 2006. The Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística--IBGE) and the City Health Department (Secretaria Municipal de Saúde) provided the data sources, and causes of death were reviewed and reclassified based on reports from the Institute of Legal Medicine (Instituto Médico Legal). The information zones were classified into four social strata according to income and schooling. The ratio between mortality rates (inequality ratio) was calculated and confirmed a rise of 98.5% in the homicide rate. In 2000, the risk of death due to external causes and murders in the stratum with the worst living conditions was respectively 1.40 and 1.94 times greater than in the reference stratum. In 2006 these figures were 2.02 and 2.24. The authors discuss the implications for inter-sectoral public policies, based on evidence from the study's findings.
采用信息区作为分析单位开展了一项生态研究，以评估巴西巴伊亚州萨尔瓦多市 2000 年和 2006 年因外部原因和凶杀导致的死亡率的社会空间不平等变化情况。巴西地理与统计研究所（Instituto Brasileiro de Geografia e Estatística--IBGE）和市卫生局（Secretaria Municipal de Saúde）提供了数据源，根据法医学研究所（Instituto Médico Legal）的报告对死因进行了审查和重新分类。根据收入和受教育程度，信息区被分为四个社会阶层。计算了死亡率的比例（不平等比例），并证实凶杀率上升了 98.5%。2000 年，生活条件最差阶层的因外部原因导致的死亡风险和凶杀风险分别是参照阶层的 1.40 倍和 1.94 倍。2006 年，这两个数字分别为 2.02 倍和 2.24 倍。作者根据研究结果讨论了跨部门公共政策的影响。
