“In 2015, an estimated 1.3% of US adults (3 million) reported being diagnosed with IBD (either Crohn’s disease or ulcerative colitis). Prevalence differed by several sociodemographic characteristics, including age, race/ethnicity, education, and poverty.  The prevalence of IBD increased from 2001 to 2018 among Medicare beneficiaries of all race and ethnicity groups, with the highest increase rate among non-Hispanic Black adults.”
