The Human Development Index (HDI) is a composite statistic which takes into consideration three indicators: life expectancy, education (mean and estimated years of schooling) and the gross national income per capita.
Based on the value of this index, the countries are split into four categories: very high human development, high human development, medium human development and low human development.
As of April 2018, all the countries in Europe (with the exception of Moldova) are part of the high or very high human development categories.
What the map above doesn’t show is the dynamic of the HDI score for each country. So, I compared the HDI scores from 2018 (which are actually based on data collected in 2015-2016) with the HDI scores from 2010 (based on data collected in 2008-2009) and created a second map which shows the change in score for each country.
I chose 2010 because that was the year they changed the formula used to calculate the HDI rankings, so a comparison with older scores generated using the old formula wouldn’t have been relevant.
This second map shows us that over the last 8 years some countries have gained more in terms of HDI score and some less. The greatest gainers are Bosnia (+0.390), Turkey (+0.030), Estonia (+0.027), Moldova (+0.027), Poland (+0.026), Albania (+0.026) and Portugal (+0.025). At the other end we have Romania (with just a +0.004 increase), followed by Greece (+0.006), Switzerland (+0.007), Ukraine and Belarus (both with +0.009).
