Provisions within the Affordable Care Act, including the introduction of subsidized, Exchange-based coverage for lower income Americans lacking access to employer coverage, are expected to greatly expand the size and importance of the individual market. Using multiple federal surveys and administrative data from the National Association of Insurance Commissioners, we generate national-, regional-, and state-level estimates of the individual market. In 2009, the number of nonelderly persons with individual coverage ranged from 9.55 million in the Medical Expenditure Panel Survey to 25.3 million in the American Community Survey. Notable differences also exist between survey estimates and National Association of Insurance Commissioners administrative counts, an outcome likely driven by variation in the type and measurement of individual coverage considered by surveys relative to administrative data. Future research evaluating the impact of the Affordable Care Act coverage provisions must be mindful of differences across surveys and administrative sources as it relates to the measurement of individual market coverage.
平价医疗法案中的规定，包括为那些无法获得雇主保险的低收入美国人提供补贴的基于交易所的保险，预计将极大地扩大个人市场的规模和重要性。我们利用多项联邦调查和全国保险专员协会的行政数据，生成了个人市场的国家、地区和州级估计数。2009 年，拥有个人保险的非老年人数量从医疗支出调查中的 955 万人到美国社区调查中的 2530 万人不等。调查估计数与全国保险专员协会行政数据之间也存在显著差异，这可能是由于调查中考虑的个人保险的类型和衡量标准与行政数据不同所致。未来评估平价医疗法案覆盖范围规定影响的研究必须注意到与个人市场覆盖范围衡量相关的调查和行政来源之间的差异。
