Discover how current asthma prevalence on national, state and local levels can lead to disparities and affect social determinants of health.

The Asthma Equity Explorer is a free web-based database for asthma research. It provides information and insight on U.S. asthma prevalence based on social, economic and environmental factors that cause asthma. And it does so within the context of location and geography.

Allergy & Asthma Network partnered with MITRE to develop the Asthma Equity Explorer. It’s designed for researchers, scientists, health professionals and research students.

What is the Asthma Equity Explorer Research Database?

More than 25 million people in the United States have asthma, according to the U.S. Centers for Disease Control and Prevention (CDC).

The Asthma Equity Explorer allows you to go deeper into the data. Why do some communities have more asthma cases than others? Why are asthma triggers such as air pollution more common in certain areas of the country? Find out how health inequity and social determinants of health (SDOH) play a role in asthma.

For example, users of the database are able to access data on:

  • socioeconomic factors
  • particulate matter concentration in communities
  • historical HOLC (Homeowners Loan Corporation) grades that address redlining in certain communities
  • related asthma health measures on national, state, county, and city levels

How to use the Asthma Equity Explorer for real-world solutions? Community-level data can help inform asthma interventions, such as how to prevent as asthma attack. It can also help families make lifestyle decisions – such as choosing where to live or go to school.

Healthcare research beyond health statistics

Users of the database can chart asthma prevalence using up to 32 different variables, including:

  • Population race/ethnicity
  • Population income to poverty ratio
  • Residential segregation: rent vs. own
  • Education level
  • Social and environmental: environmental quality, housing, and food scarcities
  • Health outcomes: lack of access to healthy food, smoking, obesity prevalence, and poor mental health

How the Asthma Equity Explorer benefits Asthma Research

Use asthma data to gain a better understanding of prevalence and identify how to reduce developing asthma. Learn the factors that cause asthma disparities and impact social determinants of health.

The database includes:

  • multiple geographic scopes
  • interactive maps, tables, and visualizations
  • interpretations and information buttons

Users can also download datasets and customized asthma reports for more in-depth analysis.

Asthma on a geographic level

The Asthma Equity Explorer breaks down geography three ways:

  • National, broken down by state
  • State, broken down by county
  • County, broken down by census tract

Asthma heath determinant factors

There are six categories of factors to choose from:

  • Health outcomes
  • Race/ethnicity
  • Education
  • Income
  • Residential segregation
  • Social and environmental

Health outcomes may include asthma attacks, emergency department visits, hospitalizations and asthma mortality.
