5. The Gap Frame score
5.1. Calculation of the Gap Frame Score
The Gap Frame Score provides the lowest value from all 4 dimensions: planet, society, economy, and governance whereas the Average of 4 Dimensions is calculated as an average value of all 4 dimensions.
The Gap Frame Score and Average of 4 Dimensions are calculated only if sufficient data (at least 75%) for dimensions exists. This implies that values for at least 3 dimensions must be available for a given country to calculate the Gap Frame index. Consequently, the Gap Frame Score is calculated for 155 out of 196 initially considered.
The dimensions are calculated if at least 60% of data exists for related issues. In a consequence, the planet dimension is evaluated for 178 countries, society dimension for 143 countries, economy dimension for 159 countries, and the governance dimension for 155 countries.
The issues are calculated if at least 50% of data exists for related indicators. Most of the issues are calculated for the minimum of 130 countries. The exceptions are the “Equal opportunity”, “Quality of Life”, and “Sustainable production “issues that are calculated for only 43, 36, and 81 countries, respectively. This limitation comes from the fact that some indicators have available data only for the OECD countries.
To calculate the indicators, issues and dimensions values for regions, OECD countries, and the world, we require to have available data for at least 60% of respective countries. Thus, to evaluate a world value for any indicator, issue, or dimension we need to collect data for at least 118 countries whereas for OECD, for at least 21 countries.
The Gap Frame regional values for indicators are calculated as a weighted average of respective countries values, with a country inhabitants being the weight:
INDICATOR WEIGHTED AVERAGE = SUM ((Indicator Value of 1st Country * Inhabitants of 1st Country), (Indicator Value of 2nd Country * Inhabitants of 2nd Country),…,( Indicator Value of nth Country * Inhabitants of nth Country)) / SUM(Inhabitants of 1st Country, Inhabitants of 2nd Country,…, Inhabitants of nth Country)
The issues, dimensions, Gap Frame Score, and the Average of 4 Dimensions for regions, OECD and the world are calculated based on the indicators weighted average.
5.2. Strong sustainability as a basis of the Gap Frame ranking
The Gap Frame Ranking takes into consideration the Gap Frame Lowest Score in order to embed a strong sustainability approach, implying that one dimension may not be improved at the cost of another one. Experts suggest that average of the 4 dimensions suggests a “weak sustainability” whereby one dimension could be sacrificed in favour of another (e.g. the environment at the expense of economic concerns). Using the lowest score instead ensures focusing on the sore spots. And this is precisely the purpose of the Gap Frame: to highlight the biggest gap for a country to quantum leap from where they are to where they need to be. We thus provide an average country value only as an additional reference point but do not use it for ranking.
