There is a growing perception that spatial disparities in development indicators within countries are becoming more pronounced. Sub-national data are needed to inform policy makers on such matters. However, data on the sub-national level is less frequent (curated in a global setting) because sub-national administrative areas change frequently.
Yesterday was World Aids Day - an annual event to raise awareness about HIV and the global fight against it. When it comes to international data about HIV and AIDS, the cross-organisational UNAIDS program publishes age and gender disaggregated data on indicators such as prevalence, new infections and deaths. In turn, we incorporate some of these data into the World Development Indicators
Here are some highlights from the data that have been released:
1) There are more adults and children living with HIV than ever before
In 2012, there were an estimated 35.3 million adults and children living with HIV in the world. The majority of these people are in Sub-Saharan Africa and parts of Asia. As you can see from the decreasing slope of the “global” line - while people continue to become infected, the rate of new infections is going down.
