Title: Analyzing Vulnerability of Low-income Population to Extreme Heat in New York City, 2013
Description: The impact of extreme heat on health has received great attention for the increasing number of worldwide heat events. In New York City, most neighborhood-scale studies on heat-related vulnerability mainly examined the risk factors of seniors. This research aims to delve into the relationship between neighborhood characteristics (socio-demographic conditions, heat impact mitigation strategies, community resources, and health risk characteristics) and the heat-vulnerability of economically deprived population, particularly with below or at 30 percent of the Area Median Income, who has manifested symptoms of weakness to heat in New York City. As a measure of relative vulnerability to heat, the study used the difference between the number of cardiac arrests occurred during 2013 Heatwave, which is one of the most recent and the longest heat waves in the City’s historical data, and regular hot days within each Zip Code Tabulation Area. The results from the multiple linear regression analysis and Pearson’s correlation test revealed that the percent of single senior households and the number of public parks in the low-income neighborhoods are negatively associated with their heat emergencies.

Significant positive relationships were found between the percent of Black population and the number of community centers in the low-income neighborhoods.
