The following table provides summary statistics for contract job vacancies with a requirement for Haskell skills. Included is a benchmarking guide to the contractor rates offered in vacancies that have cited Haskell over the 3 months to 29 April 2017 with a comparison to the same period in 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.
