People wanting work. Looks like a steady expansion of the part timers wanting full time work.
The ratio of people out of work wanting work to vacancies. This continues to fall, and the vacancies recorded are mostly with the largest companies (over 2500 employees).
The UK participation rate.
This is the ratio of those 'in the labour force' (ie unemployed and employed) to the household population. It differs from the ONS's 'employment rate' in that it doesn't exclude those over 65 (although over 65s who want a job are still classed as 'retired').
This is still historically in very high territory but is continuing to fall - suggesting that we're not generating enough jobs to keep up with the workforce growth.
