This is on me using Google, but the international nautical flags say the letters are RI_UK. The space for number 3 meaning there was no flag of that design that represents a letter. Unfortunately, I don't think it means anything. Kind of a missed opportunity.
Federal spending on health care in 2015. The Congressional Budget Office and the Office of Management and Budget estimate that the federal government will spend more than $980 billion on health care in fiscal year 2015 (see table 1).
The United States spends a higher proportion of its GDP on health care (19.3% in ref cited, but now 16%, lagging other rich countries) than any other country in the world, except for East Timor (Timor-Leste). The number of employers who offer health insurance is declining.
