Daily contractor rates and hourly contractor rates are treated separately. When calculating average contractor rates, daily rates are not derived from quoted hourly rates or vice versa.
The chart provides a 3-month moving total beginning in 2004 of IT contractor jobs citing Windows across the Hertfordshire region as a proportion of the total demand within the Operating Systems category.
