Unemployment rate

Why is only Involuntary Unemployment is considered while calculating unemployment rates while Frictional and Structural unemployment depicts that the people are not skilled enough. And why is Voluntary Unemployment is not included if the people are not working with enough skills?

The unemployment rates that are created by statistical offices usually work like this. They add up the number of all people who are looking for work. That includes people who are "involuntary unemployment" as well as "frictional unemployment" and "structural unemployment". It does not include those people who are not looking for work and not reporting themselves as looking at job centres/ labour exchanges.

The categories "involuntary", "frictional" and "structural" are not directly measured. They are theoretical tools. Economists who use those categories (and not all agree with them) try to divide the measured unemployment rate up into those categories using mathematical tools.
