The answer is unemployment rate. It is the share of the labor force that is jobless, conveyed as a percentage. It is a lagging pointer, meaning that it normally rises or falls in the wake of changing economic conditions, rather than expecting them.

It describes unemployed people as those who are willing and available to work, and who have actively wanted work within the past four weeks.
