Subnational regional mortality inequalities are large and appear to be mostly increasing within industrialized countries, although comparative studies across high-income countries are scarce. Germany is an important country to examine because it continues to experience considerable economic disparities between its federal states, in part resulting from its former division.
We analyse state-level mortality in Germany utilizing data from a newly constructed regional database based on the methodology of the Human Mortality Database. We compare time trends (1991-2015) in the German state-level standard deviation in life expectancy to that of other large, wealthy countries and examine the association between mortality and economic inequalities at the regional level. Finally, using contour-decomposition methods, we investigate the degree to which age patterns of mortality are converging across German federal states.
Regional inequalities in life expectancy in Germany are comparatively low internationally, particularly among women, despite high state-level inequalities in economic conditions. These low regional mortality inequalities emerged 5-10 years after reunification. Mortality is converging over most ages between the longest- and shortest-living German state populations and across the former East-West political border, with the exception of an emerging East-West divergence in mortality among working-aged men.
The German example shows that large regional economic inequalities are not necessarily paralleled with large regional mortality disparities. Future research should investigate the factors that fostered the emergence of this unusual pattern in Germany.
国家以下区域的死亡率存在巨大差异,且在工业化国家内部,这种差异似乎在不断扩大,尽管针对高收入国家的比较研究相对较少。德国是一个值得研究的重要国家,因为其联邦州之间仍存在相当大的经济差距,部分原因是其曾经历过分裂。
我们利用新构建的基于人类死亡率数据库方法的区域数据库中的数据,分析德国各州的死亡率。我们将德国各州预期寿命标准差的时间趋势(1991-2015 年)与其他大型富裕国家进行比较,并研究区域经济不平等与死亡率之间的关联。最后,我们使用等高线分解方法,调查德国联邦州之间死亡率的年龄模式趋同程度。
尽管德国各州的经济条件存在高度不平等,但德国的预期寿命区域不平等在国际上相对较低,尤其是在女性中。这些低水平的区域死亡率差异是在统一后 5-10 年内出现的。在大多数年龄段,最长寿和最短寿的德国州人口之间的死亡率正在趋同,且跨越了前东西德政治边界,除了在工作年龄段男性中,死亡率出现了新的东西部差异。
德国的例子表明,大的区域经济不平等并不一定会伴随着大的区域死亡率差异。未来的研究应调查促进这种不寻常模式在德国出现的因素。
