Excess mortality can be caused by extreme hot weather events, which are increasing in severity and frequency in Canada due to climate change. Individual and social vulnerability factors influence the mortality risk associated with a given heat exposure. We constructed heat vulnerability indices using census data from 2006 and 2011 in Canada, developed a novel design to compare spatiotemporal changes of heat vulnerability, and identified locations that may be increasingly vulnerable to heat. The results suggest that 1) urban areas in Canada are particularly vulnerable to heat, 2) suburban areas and satellite cities around major metropolitan areas show the greatest increases in vulnerability, and 3) heat vulnerability changes are driven primarily by changes in the density of older ages and infants. Our approach is applicable to heat vulnerability analyses in other countries.

加拿大与高温风险相关的区域社会经济脆弱性变化的时空分析

极端炎热天气事件可能导致死亡率过高，由于气候变化，这些事件在加拿大的严重程度和频率都在增加。个人和社会脆弱性因素会影响与特定热暴露相关的死亡风险。我们使用加拿大 2006 年和 2011 年的人口普查数据构建了热脆弱性指数，开发了一种新颖的设计来比较热脆弱性的时空变化，并确定可能越来越容易受到热影响的地点。结果表明，1) 加拿大的城市地区特别容易受到高温的影响，2) 郊区和主要大都市区周围的卫星城市的脆弱性增加幅度最大，3) 高温脆弱性的变化主要是由老年人密度的变化驱动的。年龄和婴儿。
