This Statistical Brief compares summary statistics on health care expenditures and expenditure distributions by type of service and sources of payment for the elderly (age 65 and over) in 2001, 2006, and 2011. The estimates are derived from data collected in the Medical Expenditure Panel Survey Household (MEPS-HC) and Medical Provider Components (MEPS-MPC) on the U.S. civilian noninstitutionalized population. Health care expenses in MEPS represent payments to physicians, hospitals, and other health care providers for services reported by respondents to the MEPS-HC. Estimates for 2001 and 2006 were adjusted to 2011 dollars based on the Gross Domestic Product (GDP) Price Index to remove the impact of medical price inflation on comparisons (http://www.meps.ahrq.gov/mepsweb/about_meps/Price_Index.shtml). All differences between estimates noted in the text are statistically significant at the 0.05 level or better.
本统计简报比较了2001年、2006年和2011年老年人（65岁及以上）按服务类型和支付来源划分的医疗保健支出及支出分布的汇总统计数据。这些估计数来自医疗支出小组调查家庭（MEPS-HC）和医疗服务提供者组成部分（MEPS-MPC）收集的关于美国非机构化平民人口的数据。MEPS中的医疗保健费用是指就MEPS-HC的受访者报告的服务向医生、医院和其他医疗保健提供者支付的费用。2001年和2006年的估计数根据国内生产总值（GDP）价格指数调整为2011年美元，以消除医疗价格通胀对比较的影响（http://www.meps.ahrq.gov/mepsweb/about_meps/Price_Index.shtml）。文本中指出的估计数之间的所有差异在0.05水平或更高水平上具有统计学意义。
