The paper provides a first systematic, comprehensive benchmarking of South Africa's infrastructure performance in four major sectors--electricity, water and sanitation, information and communication technology, and transportation--against the relevant group of comparator countries using a new World Bank international data base with objective and perception-based indicators of infrastructure performance from over 200 countries. Specifically, the paper seeks to answer a number of relevant questions: How does South Africa compare on major indicators of infrastructure sector performance against the relevant country groups? What do outcome indicators tell us about the relative strengths and weaknesses of South Africa's infrastructure compared with various income and geographical comparator groups of countries? Where are the largest deviations-positive and negative-from the benchmarks and other comparators? And how does one interpret some of these comparisons to be useful for policy purposes?
