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 two countries had similar healthcare systems before Canada changed its system in the 1960s and 1970s. The United States spends much more money on healthcare than Canada, on both a per-capita basis and as a percentage of GDP. In 2006, per-capita spending for health care in Canada was US$3,678; in the U.S., US$6,714. The U.S. spent 15.3% of GDP on healthcare in that year; Canada spent 10.0%. In 2006, 70% of healthcare spending in Canada was financed by government, versus 46% in the United States.
