The Nabarro Infrastructure Index is a composite index, based on empirical and verifiable sources, which we have aggregated and weighted for application to listed countries to provide what we think is a unique tool to assist in the decision-making process. The Index includes 20 countries representing five major world regions: Asia-Pacific, Europe, Latin America, Middle East/North Africa and North America.The Nabarro Infrastructure Index, for different countries, is intended to: assist in evaluating the attractiveness for investment in infrastructure; benchmark current and predict future relative performance in the Nabarro Infrastructure Index; and identify and encourage improvements in the conditions for investment in infrastructure.
