Katadata recently launched Databoks, an online portal for Indonesia national and subnational data. The service is available for public use, and now hosts more than 1 million data points covering multiple categories and industrial subsectors, from various formal sources. The data provided is available down to the province level and soon, also at the district (Kabupaten/Ibukota) level. The resources currently are available in Indonesian language.
