The distribution of health care expenditures remains highly concentrated, but most Americans use few health care resources and have low out-of-pocket spending. More than 93 percent of "low spenders" (those in the bottom half of the population) believe they have received all needed care in a timely manner. The low spending by the majority of the population has remained almost unchanged during the thirty-seven-year period examined.
医疗保健支出的分布仍然高度集中，但大多数美国人使用的医疗资源很少，自付支出也很低。超过 93%的“低支出者”（即人口中处于下半部分的人群）认为他们及时获得了所需的全部医疗服务。在 37 年的研究期间，大多数人口的低支出基本保持不变。
