Analysis of the ratio of staff in policy-development departments to the total staff of ministries (expressed as a percentage), based on four selected ministries: the ministry responsible for agriculture, the ministry responsible for trade/economy, the ministry responsible for the environment and the ministry responsible for social affairs or the equivalent. The ratio is calculated by dividing the number of staff in ministerial policy development departments (including departments leading on sector policies, legal, analytical and EI departments) by the total number of staff of the ministry, including staff working in any structural units of the ministry who work on enforcement and inspection.
