The Social Security Administration 1972 Survey of Disabled and Nondisabled Adults showed that an estimated 15.6 million adults aged 20--64, or 15 percent of the total noninstitutionalized population of those ages, were disabled as a result of some chronic condition or impairment. Yet more than three times as many persons (51.8 million) reported that they suffered from one or more chronic health conditions. The diseases reported most frequently by the adult population of working age were cardiovascular and musculoskeletal disorders, each with prevalence rates of 200 persons per 1,000 population. The prevalence rate for neurological disorders was only 7 persons per 1,000; their disabling potential, however, was much greater than that for the diseases with the highest prevalence rates: 80 percent of those suffering from neurological disorders were also currently disabled. For almost every disease group, older persons were more likely to suffer from a chronic condition or impairment and more likely to be disabled as a result. Women were more likely than men to report a chronic disease or impairment and more likely to be severely disabled as a result. White persons were somehwat more likely than blacks and members of other races to report one or more chronic conditions but less likely to be disabled as a result and even less likely to be severely disabled. Among the nondisabled, less than one-tenth reported a condition caused by accident or injury but close to one-fourth of the disabled reported a disease or impairment of accidental origin.
社会保障管理局1972年对残疾和非残疾成年人的调查显示，估计有1560万年龄在20至64岁之间的成年人，即该年龄段非机构化总人口的15%，因某种慢性疾病或损伤而致残。然而，报告称自己患有一种或多种慢性健康问题的人数（5180万）是前者的三倍多。劳动年龄成年人口中报告最频繁的疾病是心血管疾病和肌肉骨骼疾病，每1000人中各有200人患病。神经疾病的患病率仅为每1000人中有7人；然而，其致残可能性比患病率最高的疾病要大得多：80%的神经疾病患者目前也处于残疾状态。几乎对于每个疾病组来说，老年人更有可能患有慢性疾病或损伤，也更有可能因此致残。女性比男性更有可能报告患有慢性疾病或损伤，也更有可能因此严重致残。白人比黑人和其他种族成员略微更有可能报告患有一种或多种慢性疾病，但因此致残的可能性较小，严重致残的可能性更小。在非残疾人群中，不到十分之一的人报告有因意外事故或受伤导致的疾病，但在残疾人群中，近四分之一的人报告有一种或多种因意外导致的疾病或损伤。
