Daniel: The GMR progress assessment is based on comparing, for each country and indicator, the annualized progress rate vis-à-vis the target progress rate required to achieve the goal. Our underlying data reveals that countries started from very different initial conditions. Two of the interactive data visualizations in our suite of six MDG dashboards show the differences between countries in terms of starting conditions, trends and changes in rate of progress made since 1990. You can explore these here: http://data.worldbank.org/mdgs/compare-trends-and-targets-of-each-mdg-indicator and here http://data.worldbank.org/mdgs/trends-and-projections-of-each-mdg-indicator-for-each-country. These visualizations will also help you identify the few countries/indicators for which progress rates may exhibit “diminishing returns”.
