For decades, public health, health services research, and medical studies have continued to show evidence that racial and ethnic minority groups experience healthcare disparities that can lead to dramatic differences in health outcomes. The care they receive as patients can cause increased rates of illness and shorter lifespans. The Census Bureau projects that minority groups¹ will account for more than half of the U.S. population by 2045, therefore focusing on improving minority health and working to eliminate disparities is a critical effort for the Nation.

The poorer outcomes among minority populations may be attributable to such healthcare-related risk factors as provider biases, poor provider-patient communication, lower levels of health literacy, and systemic racism and bias.

A large body of research has shown that compared with the White population, racial and ethnic minority groups experience disparities in access to care and healthcare quality, including effectiveness of treatment, timeliness, patient safety, and preventive screening. For example, stark disparities exist for preventive screening, such as for lipid disorders, which is recommended to identify potential lipid disorders and prevent heart disease. A recent study found that 67 percent of non-Hispanic White women reported prior screening compared with 43 percent of non-Hispanic Black women.²

Asian Americans have also been shown to experience disparities in care. For example, a 2020 study found that Asian Americans, including Asian ethnic-groups, reported lower rates of patient-provider communication regarding breast and cervical cancer screening compared with White Americans.³

Clinician attitudes can affect quality of care for racial and ethnic minority groups. In a 2022 study, 19 percent of American Indian or Alaska Native individuals living in rural areas reported experiencing discrimination from a doctor or health clinic compared with 3 percent for White Americans.⁴

The 2022 National Healthcare Quality and Disparities Report presents evidence that disparities for most measures are not changing. The table below shows the number of quality measures for which racial or ethnic groups experienced better, same, or worse quality of care than White groups in the most recent data year.

Key: n = number of measures; AI/AN = American Indian or Alaska Native; NHPI = Native Hawaiian/Pacific Islander.
Note: The most recent data year varies for each measure and may be 2017, 2018, 2019, or 2020. The number of measures with data available varies by group.

Health disparities result from inequities in the determinants of health, including social, environmental, healthcare, and genetic factors. Health equity has been defined as the attainment of the highest level of health for all people, where everyone has a fair and just opportunity to attain their optimal health regardless of race, ethnicity, disability, sexual orientation, gender identity, socioeconomic status, geography, preferred language, or other factors that affect access to care and health outcomes.⁵

Social determinants of health are the nonmedical factors that influence health outcomes. They are the conditions in which people are born, grow, work, live, and age, and the wider set of forces and systems shaping the conditions of daily life.⁶ Addressing social determinants of health is another AHRQ priority.

Examples of AHRQ's work to reduce and document disparities in healthcare and work toward health equity includes:

• 2022 National Healthcare Quality and Disparities Report.
• Chartbook on Healthcare for Asians and Native Hawaiians/Pacific Islanders.
• Chartbook on Healthcare for Hispanics.
• Chartbook on Health Care for Blacks.
• AHRQ Social Determinants of Health website.
