Method
Approval rate = approved ÷ (approved + refused) over the public planning decisions we hold for Merthyr Tydfil, matched to a type of work from the application description. We lead with the last few years so the figure reflects how Merthyr Tydfil decides today, with the longer record as context. A rate is only shown once there are enough decided applications for it to be reliable. We publish aggregate figures only, never an individual application or applicant name.
