No, it's not titled misleadingly. The title is:
U-3 Total unemployed, as a percent of the civilian labor force (official unemployment rate)
That is 100% accurate. To be unemployed, you must be searching for work. This measures exactly that and is, by definition of all the terms, the unemployment rate in the nation.
What can be misleading are the definitions that it is based on, because it provides a narrower picture than is sometime helpful. The U-6 is not, by definition, the unemployment rate in the country, despite the fact that it gives a better picture of the labor market **when put in context with the unemployment rate**. Without the U-3 to base things off of, the U-6 is meaningless *because* it encompasses so much.
So no, your original statement is incorrect in every possible way.
