Summary Definition, Methodology for Collection and Calculation

Alternative Data Sources

The data for each indicator on African Health Stats (AHS) are published by the UN agency, or UN inter-agency group, which holds responsibility for global monitoring of the indicator. This varies by indicator. Please refer to ‘Data Source’. AHS uses data from these sources because such data are internationally comparable and it is the mandate of those agencies to prepare such data and monitor progress internationally. In some cases the UN agency has made adjustments to the data in order to make national data internationally comparable, for example they may adjust national estimates to account for differences in survey design, the extent of potential underreporting, and the definition of what is being measured (eg. maternal deaths). This means that at times there may be discrepancies between national and international estimates. Individual countries may prefer to instead rely on national figures for national monitoring. For uniformity, AHS uses only international estimates of the UN agencies in data visualisations.

In 2014, the following countries communicated that they use alternative figures to monitor the indicator HIV and TB Treatment instead of the figures that appear in AHS data visualisations. The most recent alternative figure supplied by these countries in 2014, by source are: NA.
