Sources and processing

This data is based on the following sources

UNAIDS leads the world's most extensive data collection on HIV epidemiology, programme coverage and finance and publishes the most authoritative and up-to-date information on the HIV epidemic.

In some cases there is no data for some country and year. This can be a result of very small epidemics among women in the reproductive age which makes estimation of the mother to child transmission very unstable. Another reason for missing data is that relevant authorities may have asked UNAIDS not to share their estimates.

This report makes clear that there is a path to end AIDS. Taking that path will help ensure preparedness to address other pandemic challenges, and advance progress across the Sustainable Development Goals. The data and real-world examples in the report make it very clear what that path is. It is not a mystery. It is a choice. Some leaders are already following the path—and succeeding. It is inspiring to note that Botswana, Eswatini, Rwanda, the United Republic of Tanzania and Zimbabwe have already achieved the 95–95–95 targets, and at least 16 other countries (including eight in sub-Saharan Africa) are close to doing so.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
