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).
Government funds nearly two-thirds of U.S. health care costs: American Journal of Public Health study. Contrary to popular perceptions, taxpayers fund 64 percent of U.S. health care, more public dollars per capita than the citizens of other nations â including those with universal health programs.
