About GDI

Concept
The Grant Thornton Global Dynamism Index was developed in conjunction with the Economist Intelligence Unit (EIU). Drawing on both economic indicators and survey data, it ranks 50 economies across the globe on their dynamism, that is the changes to each economy which have enabled recovery from the 2008-09 economic recession and are likely to lead to a fast rate of future growth

Indicators
Categories and indicators were selected on the basis of expert analysis by the EIU. Indicators are drawn from a variety of sources, including: the EIU, the World Bank, Thomson Financial and UNESCO. Please refer to figure 14 in the full report for a full list of indicators and sources.

Data modelling
Modelling the indicators and categories results in scores of 0-100 for each country, where 100 represents the most dynamic environment and 0 the least. The overall score, as well as the category scores, are averages of the normalised scores for each of the indicators. Each economy is then ranked according to these scores. Indicator scores are normalised and then aggregated across categories to enable a comparison of broader concepts across countries. Normalisation rebases the raw indicator to a common unit so that it can be aggregated. The indicators where a higher value means a more favourable environment eg. real GDP growth have been normalised on the basis of: x = (x-Min(x)) / (Max(x) – Min(x)), where Min(x) and Max(x) are respectively the lowest and highest values in the 50 economies for any given indicator. The normalised value is then transformed from 0-1 to a 0-100 score to make it directly comparable with other indicators. This in effect means that the country with the highest raw data value will score 100, and the lowest scores 0. The indicators where a higher value means a less favourable environment eg. unemployment, have been normalised on the basis of: x = (x-Max(x)) / (Max(x) – Min(x)).

Survey
The survey of 406 senior executives was conducted by the Thought Leadership team at the EIU. The sample breakdown is shown below:
• 29% of respondents were CEOs, a further 23% were in other C-Suite or board roles, and the remainder occupied other senior decisionmaking roles
• 49% of businesses represented in the survey had global annual revenues exceeding $500m
• 33% of respondents were based in North America, followed by Asia-Pacific, Europe (both 26%), Middle East & Africa (8%) and Latin America (7%)
• 19 different sectors were represented in the survey, led by financial services (14%), professional services (11%), technology (10%) and manufacturing (9%).

Weighting
Survey respondents were asked to assign an importance to each of the indicators for their company, translating to the weight seen in figure 14 in the full report. Each category was weighted evenly.
