Cities of Opportunity is a continually evolving project created for cities, their leaders, businesses, and citizens seeking to improve their economies and quality of life. The report is based on publicly available information supported by extensive research. Three main sources are used: Global multilateral development organizations such as the World Bank and International Monetary Fund, national statistics organizations, such as UK National Statistics and the US Census Bureau, and commercial data providers. The data were collected during the latter half of 2011 and first quarter of 2012. In the majority of cases, the figures used in the study refer to 2010 and 2011 data. In some cases, national data are used as a proxy for city data. Care has been taken to ensure that, where used, national data closely reflects city data. The scoring methodology was developed to ensure transparency and simplicity, as well as comparability across cities.
Taking the data for each individual variable, the 27 cities are sorted from the best performing to the lowest performing. The cities are then assigned a score from 27 (best performing) to 1 (lowest performing). Once all 60 variables are ranked and scored, they are placed into their 10 indicators. Within each group, the variable scores are then summed to produce an overall indicator score for that topic. This produces 10 indicator league tables that display the relative performance of our 27 cities.
