The adjusted 2018 prevalence of ESRD increased dramatically with age, with young adults (22-44 years) having prevalence of approximately 1,024 per million, and older adults (65-74 years) having a prevalence of 7,401.6 per million. People aged 75+ years had a slightly lower prevalence (7,232.5 per million) than people aged 65-74 years, likely because of competing mortality risk with advanced age. Males had higher prevalence (~1,000 per million greater) of ESRD than females. Native Hawaiian/Pacific Islanders had the greatest prevalence of ESRD (approximately 17,600 per million) compared to all other racial groups. ESRD was most common in people with assigned causes of diabetes (884 per million) and hypertension (604 per million). People with glomerulonephritis (347 per million), cystic kidney (117 per million) and other assigned causes (including missing and unknown; <400 per million each) had lower but still substantially high prevalence of ESRD.
