US health care spending increased 4.6 percent to reach $3.6 trillion in 2018, a faster growth rate than the rate of 4.2 percent in 2017 but the same rate as in 2016. The share of the economy devoted to health care spending declined to 17.7 percent in 2018, compared to 17.9 percent in 2017. The 0.4-percentage-point acceleration in overall growth in 2018 was driven by faster growth in both private health insurance and Medicare, which were influenced by the reinstatement of the health insurance tax. For personal health care spending (which accounted for 84 percent of national health care spending), growth in 2018 remained unchanged from 2017 at 4.1 percent. The total number of uninsured people increased by 1.0 million for the second year in a row, to reach 30.7 million in 2018.
2018 年美国医疗保健支出增长 4.6%，达到 3.6 万亿美元，高于 2017 年 4.2%的增长率，但与 2016 年的增长率持平。2018 年，医疗保健支出占经济的比重从 2017 年的 17.9%降至 17.7%。2018 年整体增长加速了 0.4 个百分点，这主要是由于私人医疗保险和医疗保险的增长加快，这受到医疗保险税恢复的影响。对于个人医疗保健支出（占国家医疗保健支出的 84%），2018 年的增长率与 2017 年持平，为 4.1%。连续第二年，无保险人数增加了 100 万，达到 2018 年的 3070 万。
