Heat Vulnerability Index for New York State

The New York State Department of Health (NYSDOH) has recently released census-tract level data for heat vulnerability. Defined as the ‘likelihood of injury or harm during periods of hot weather’, heat vulnerability has been associated with environmental and sociodemographic characteristics including housing density, proximity to open spaces, race, income, and language spoken. Thirteen (13) individual variables comprise the Heat Vulnerabiltiy Index. More information on the methodology and specific data included can be found here, and in their article published in 2018 here.

As shown in the map, while census tracts within cities generally have higher values of heat vulnerability, there is variability within cities (such as in the city of Rochester) and in rural areas as well.

Additional data from the NYSDOH includes the components of the Heat Index and may be displayed and overlaid on the Heat Vulnerability map in the RocHealthData map room.
