The Doing Business project provides objective measures of business regulations and their enforcement across 189 economies and selected cities at the subnational and regional level. The ease of doing business score helps assess the absolute level of regulatory performance over time. It captures the gap of each economy from the best regulatory performance observed on each of the indicators across all economies. One can both see the gap between a particular economy's performance and the best performance at any point in time and assess the absolute change in the economy's regulatory environment over time as measured by Doing Business. The latest version of the index was updated in 2019.
