Foreign-born adults in Los Angeles County, California, constituted 45 percent of the county's population ages 18-64 but accounted for 33 percent of health spending in 2000. Similarly, the undocumented constituted 12 percent of the nonelderly adult population but accounted for only 6 percent of spending. Extrapolating to the nation, total spending by the undocumented is 6.4 billion dollars , of which only 17 percent (1.1 billion dollars) is paid for by public sources. The foreign-born (especially the undocumented) use disproportionately fewer medical services and contribute less to health care costs in relation to their population share, likely because of their better relative health and lack of health insurance.
加利福尼亚州洛杉矶县的外国出生成年人占该县18 - 64岁人口的45%，但在2000年却占医疗支出的33%。同样，无证移民占非老年成年人口的12%，但支出仅占6%。据推算，全国无证移民的总支出为64亿美元，其中只有17%（11亿美元）由公共资金支付。外国出生者（尤其是无证移民）相对于其人口比例而言，使用的医疗服务少得多，对医疗保健成本的贡献也较小，这可能是因为他们相对健康状况较好且缺乏医疗保险。
