3/5/2023 0 Comments Big weather events in 2006Overall, a total of more than 11,000 Americans have died from heat-related causes since 1979, according to death certificates. ![]() Between 19, the death rate as a direct result of exposure to heat (underlying cause of death) generally hovered between 0.5 and 2 deaths per million people, with spikes in certain years (see Figure 1).* This graph shows data for the Chicago Standard Metropolitan Statistical Area.ĭata sources: CDC, 2012 16 NOAA, 2012 17 15 Differences in estimated heat-related deaths that result from different methods may be even larger when considering the entire nation and longer time periods. 14 However, studies that compared the total number of deaths during this heat wave (regardless of the recorded cause of death) with the long-term average of daily deaths found that the heat wave likely led to about 700 more deaths than would otherwise have been expected. For example, during a severe heat wave that hit Chicago* between July 11 and July 27, 1995, 465 heat-related deaths were recorded on death certificates in Cook County. 13 Studies of heat waves are one way to better understand health impacts, but different methods can lead to very different estimates of heat-related deaths. ![]() Many factors can influence the nature, extent, and timing of health consequences associated with extreme heat events.
