Any mental illness refers to any mental, emotional, or behavioral disorder, regardless of the level of impairment it has on a person's life or functioning. Serious mental illness, which affects a smaller share of the population, is a mental, emotional, or behavioral disorder that substantially impairs a person's ability to function and limits or interferes with major life activities.
More Oklahoma adults have experienced mental illness in recent years.
Oklahoma's rates of depression and serious mental illness are higher than national averages.

Note: The gap after 2018-2019 data exists because estimates for 2021-2022 cannot be compared to estimates from previous years due to changes in NSDUH survey methodology.
A major depressive episode is a period of at least two weeks in which a person has a depressed mood or loss of interest or pleasure in daily activities. This can include problems with sleep, eating, energy, concentration, and self-worth.

Suicidal ideation means thinking about, considering, or planning suicide.
In recent years, county suicide rates have been higher in eastern and southern Oklahoma.
With about 21 deaths for every 100,000 residents, Oklahoma has the ninth-highest suicide rate in the country. Most of these suicides are firearm deaths.
