Geographic patterns of county prevalence rates of disability benefit receipt are shown for the Social Security Administration's Disability Insurance (DI) and Supplemental Security Income (SSI) programs. Prevalence rates were calculated by dividing each county's December 1990 DI and SSI disability caseloads by the population aged 18-64 for that year in that county. Separate maps were also constructed for men and women recipients. Areas with the highest overall DI prevalence rates included Appalachia, the Southeast Coastal Plains, the Mid-south, northwestern Montana, the coastal counties of Washington, and isolated counties of the Southwest. Areas with the highest SSI prevalence rates included the Mississippi Delta, scattered counties in Oklahoma, the Missouri "Boot Heel," parts of Appalachia, isolated counties in South and North Dakota, the "Four Corners" regions of the Southwest, the Sacramento and San Joaquin Valley regions of California, isolated parts of the upper Great Lakes States, northern Maine, and the coastal region of southwestern Alaska. Disability prevalence rates were also calculated for the overall population and by sex for each of the 10 U.S. Department of Health and Human Services administrative regions.
图中展示了社会保障管理局的伤残保险（DI）和补充保障收入（SSI）项目中各县领取残疾福利金患病率的地理分布情况。患病率通过将1990年12月各县的DI和SSI残疾案例数量除以该县当年18 - 64岁的人口数量得出。还分别为男性和女性领取者绘制了地图。DI总体患病率最高的地区包括阿巴拉契亚地区、东南沿海平原、中南部、蒙大拿州西北部、华盛顿州的沿海县以及西南部的一些孤立县。SSI患病率最高的地区包括密西西比三角洲、俄克拉荷马州的一些零散县、密苏里州的“靴跟”地区、阿巴拉契亚地区的部分地区、南达科他州和北达科他州的一些孤立县、西南部的“四角”地区、加利福尼亚州的萨克拉门托和圣华金河谷地区、五大湖州上游的一些孤立地区、缅因州北部以及阿拉斯加西南部的沿海地区。还计算了美国卫生与公众服务部10个行政区中总人口以及按性别划分的残疾患病率。
