Sierra Leone - Distance to frontier score (0=lowest performance to 100=frontier)

Definition: Distance to frontier score illustrates the distance of an economy to the "frontier," which represents the best performance observed on each Doing Business topic across all economies and years included since 2005. An economy's distance to frontier is indicated on a scale from 0 to 100, where 0 represents the lowest performance and 100 the frontier. For example, a score of 75 in 2012 means an economy was 25 percentage points away from the frontier constructed from the best performances across all economies and across time. A score of 80 in 2013 would indicate the economy is improving.

Development Relevance: The distance to frontier score aids in assessing the absolute level of regulatory performance and how it improves over time. This allows users both to see the gap between a particular economy's performance and the best performance at any point in time and to assess the absolute change in the economy's regulatory environment over time as measured by Doing Business. In this way the distance to frontier measure complements the annual ease of doing business ranking, which compares economies with one another at a point in time.
