Adults with a recent asthma attack

Adults reporting an asthma diagnosis, and symptoms, in the last 12 months (from when they were surveyed). Poor air quality and housing issues increase risk of developing and triggering asthma.

Secondhand smoke at home

Adults reporting secondhand smoke at home. Secondhand smoke, especially indoors, is bad for health - particularly for the health of children.

Homes with cracks or holes

Households reporting cracks or holes in the home. This maintenance problem is linked to mice, rats, and cockroaches - which can harm residents' health.

Homes with leaks

Households reporting leaks from outside the unit. This maintenance problem can introduce mold, which can worsen respiratory conditions like asthma.

Neighborhood poverty

The percent of households with incomes below the federal poverty level. Households without sufficient resources are often deprived of access to health care, good quality housing, and other resources that protect health.

Homes with cockroaches

The presence of cockroaches in the home is often associated with poor housing maintenance. Cockroaches in the home can contaminate food and worsen asthma.

No smoke-free home policy

Adults without a smoke-free home policy. A smoke-free home policy can limit people's exposure to secondhand smoke, which is especially dangerous to children.

Adults reporting mice or rats inside

Mice and rats are a source of household allergens connected to developing or worsening asthma.

Asthma emergency department visits due to PM2.5

ED visits for asthma due to PM2.5 air pollution. These represent part of the health burden of air pollution.

Asthma emergency departments visits due to Ozone

ED visits for asthma due to ozone. These are part of the health burden of air pollution.

Asthma hospitalizations due to Ozone

Hospitalizations for asthma due to ozone. These are part of the health burden of air pollution.

Health insurance (adults)

Adults with any kind of health insurance. People with health insurance are more likely to have a regular doctor, receive preventive care services, better manage chronic health conditions, have longer life expectancy, and more.

Asthma emergency department visits (age 5 to 17)

Emergency department visits for asthma. Things like smoke, air pollution, dust mites, cockroaches, mold, pollen and pet dander can trigger asthma.

Asthma hospitalizations (age 5 to 17)

Hospitalizations for asthma. These more severe asthma outcomes are often clustered in high-poverty neighborhoods, where disinvestment and poor housing conditions expose residents to triggers.

Renter-occupied homes with any health-related housing problems

Renter-occupied homes with any health-related housing problems. Homes with housing problems can threaten the health of the people who live there.

Fine particles (PM 2.5)

Concentration of fine particles in the air. Fine particles are emitted by vehicles, building boilers, and other combustion — and are a major form of air pollution that harms health. Neighborhood sensors measure PM2.5 at the street-level, where people are most active. These sensors are designed to let us measure differences in air pollution over time and locations within New York City.

Ozone (O3)

Concentration of ozone in the air. Ozone is a common air pollutant that can harm breathing and worsen respiratory conditions.
