I my country you have to regularly check in with the bureau for unemployment to be included in the stats, even though that bureau hadn’t found a job for anyone ever.
I assume that’s how it works in many other countries.
Unemployed is the one actively looking for a job, not the one that’s just to working. At least that’s how governments seem to look at it, and their way of figuring out who’s looking is incorrect.
Where do you live? Most countries use labour force surveys, it's orthogonal to registration to unemployment agencies.
