In 1971, 44 percent of workers who had been currently entitled to social security disability insurance (DI) benefits for 1 year or more also received benefits from at least one other source. Their average disability insurance benefit was higher than that of persons who received only DI benefits. On the average, total benefits to those receiving multiple benefits were double the amounts paid to those receiving only DI benefits. The combined benefits for the former produced median replacement rates about 50 percent larger than the median replacement rates for the latter. High replacement rates--defined here as more than 80 percent of predisability earnings replaced by benefit--predominate among those with multiple benefits. Considering replacement rates based solely on disability insurance benefits substantially understates the extent to which benefits from public and private programs actually replace predisability earnings. Replacement rates based solely on DI benefits are generally higher for those receiving DI benefits only than for persons receiving multiple benefits. Limiting DI benefits to the replacement rate from DI benefits alone is disadvantageous for persons who receive only DI benefits, compared with those who also receive other benefits.
1971年,当时已领取社会保障伤残保险(DI)福利达一年或一年以上的工人中,44%还从至少一种其他来源领取福利。他们的平均伤残保险福利高于仅领取DI福利的人。平均而言,领取多种福利者的总福利是仅领取DI福利者所获金额的两倍。前者的综合福利产生的中位数替代率比后者的中位数替代率约高50%。高替代率(这里定义为福利替代伤残前收入的80%以上)在领取多种福利者中占主导。仅考虑基于伤残保险福利的替代率,会大大低估公共和私人项目的福利实际替代伤残前收入的程度。仅基于DI福利的替代率,通常领取DI福利者比领取多种福利者更高。与还领取其他福利的人相比,仅将DI福利限制在仅基于DI福利的替代率,对仅领取DI福利的人不利。
