The website https://sdg-tracker.org/ provides excellent summaries and visualisations on Sustainable Development Goals (SDG). From the website:
The United Nations Sustainable Development Goals (SDGs) are targets for global development adopted in September 2015, set to be achieved by 2030. Here we present data across all available indicators from the Our World in Data database tracking progress towards these goals around the world.
Warning the website is addictive, offering a range of visuals that are often surprising.
The data on inequality reflects the gap in data for many countries. In the chart below we see the annual average growth rate per capita of income/consumption in the bottom 40 percent of the population. The data is important and interesting, but there is limited data available for the African continent, and South Africa (where this blog is produced). This is not the fault of the SDG tracker website, but rather the fault of government’s which either do not produce the data or do not share the data.
Nonetheless, the site provides an accessible resource to understanding the available data through various visualisations. Also, note that further statistics, analysis and visuals on inequality can be found at our entries on Income Inequality, Incomes across the Distribution and Global Economic Inequality.
