The table below looks at the prevalence of the term Clustering in contract job vacancies. Included is a benchmarking guide to the contractor rates offered in vacancies that have cited Clustering over the 3 months to 24 April 2017 with a comparison to the same period over the previous 2 years.

Note that daily and hourly rates are treated separately in these statistics. When calculating contractor rate percentiles, daily rates are never derived from quoted hourly rates or vice versa.
