You need to fact check your 28%. Obviously, no one actually knows how many people have bi-polar, but 1.5% is a common guess, or about 4.5 million people. It undermines the issue when writers throw wild numbers around. I know of no authority for the 28% number.
Ed. Note: The statistics cited for this article are from the National Institute of Mental Health (NIMH). According to the NIMH, “mental disorders are common in the United States and internationally. An estimated 26.2 percent of Americans ages 18 and older—about one in four adults—suffer from a diagnosable mental disorder in a given year.” The article did not cite a 28 percent figure.
The NIMH categorizes mental illness by diagnosis, and the statistics pertaining to bipolar disorder show that this disorder affects “approximately 5.7 million American adults, or about 2.6 percent of the U.S. population age 18 and older in a given year.”
