The Human Development Report Office (HDRO) offers this REST API for the developers to query human development related data in JSON format. The data can be queried by indicator id(s), year(s) and country code(s) and group by any order.
Data in this API is updated annually, upon the publication of the global Human Development Report. With each update the data present in the API (MySQL) database is wiped and replaced with the new data. This is due to the fact that the data is recalculated retroactively each year, in light of new methodologies and changes.
