Population living in poverty, compared to 12.5% national average. (2019 ACS - US Census)


Population living alone, compared to 15% national average. (2019 ACS - US Census)


The frequency of heat waves in NYC has been increasing in recent years. However, its impact is disproportionately higher on racially and socioeconomically marginalized neighborhoods such as the South Bronx and northern Manhattan – communities already burdened by environmental racism, leaving them with more exposure to polluting industries and often little to no greenspace in which to seek refuge from the heat and poor air quality. As a result, there are stark environmental health disparities: while African-Americans constitute just under 25% of NYC’s population, they made up almost half of those who lost their lives to heat between 2000 and 2012.

Campaign Goals / Anticipated Outcomes

Collaborate with local grassroots environmental justice groups to recruit resident participants who can collect temperature-related data as citizen scientists in the target neighborhoods, centering participant empowerment.
Contribute to ongoing efforts by NYC to assess social and environmental determinants of health that compound heat health inequities.
Leverage this data to identify action items at different levels ranging from local community boards to the city, including expanding existing efforts targeted to vulnerable neighborhoods.
