The business rankings model measures the quality or attractiveness of the business environment in the 82 countries covered by The Economist Intelligence Unit’s Country Forecast reports. It is designed to reflect the main criteria used by companies to formulate their global business strategies, and is based not only on historical conditions but also on expectations about conditions prevailing over the next five years. This allows the Economist Intelligence Unit to utilise the regularity, depth and detail of its forecasting work to generate a unique set of forward-looking business environment rankings on a regional and global basis.
