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).
In 1980, we spent $1,110 per person on health care, which worked out to about 9.2 percent of Gross Domestic Product. But in the 1980s, health-care costs in the United States began growing much faster than in other countries, rising to $9,810 per person in 2013. That amounts to a total of $2.74 Trillion spent on health care, or 17.9% of our total economy. Health Care Cost Statistics.
