Our definition of infrastructure is wide-ranging, encompassing a number of broad sectoral groupings and economic activities. We cover the sectors traditionally classified as infrastructure such as transportation and utilities, but also analyse enabling capital projects in sectors such as extraction, manufacturing, and social infrastructure. This year, we have broken out telecommunications infrastructure from the broader category of utilities in recognition of its increasing importance in wired and wireless global communications over the coming decade.
The data set for this study includes 49 of the world’s largest and fastest growing economies, covering 88% of total world fixed investment spending. Infrastructure spending forecasts are broken down for each of the 49 countries, seven geographical regions and six industrial sectors.
In developing this analysis, we used data sets to provide consistent, reliable, and repeatable measures of projected capital project and infrastructure spending globally as well as by country. Historical spending data is drawn from government and multinational organisation statistical sources.
The analysis, completed over the first half of 2015, incorporates all available information at that time. Projections are based on proprietary economic models developed by Oxford Economics at the country and sector levels. For more information on the methodological basis for these projections, please see the global report.
