Notes About the Data

  • Heat-related illness occurs when the body’s natural temperature controls become overloaded. Climate change and our built environment both contribute to extreme heat. For more information…
  • Data Sources: Multiple Causes of Death Files from the Center for Health Statistics, 2000-2011. Patient Discharge Data (2000-2012) and Emergency Department Data (2005-2012) from the Office of Statewide Health Planning and Development. For more information…
  • The 95% Confidence Interval (CI) is the range of values that likely contains the true heat-related event rate per 100,000 in the population. For more information...
  • Data are not available if the number of events are less than 12.
