Fig. 8. Age Distribution of Pediatric Vehicular Heatstroke Deaths (1998-2019)


*Average Age: 26.7 months

*The methodology used to calculate average age has been modified from previous editions. Previously, reported ages in years were converted to months; for example 2-years as 24 months, 3 years as 36 months, etc. However, in rethinking the data, it was realized that a 2-year old could be anywhere from 24 to 35 months etc., so 2-year old ages were adjusted to 30 months, 3-year old ages to 42 months, etc.
