With rigorous economic research and practical policy solutions, we focus on the issues and institutions that are critical to global development. Explore our core themes and topics to learn more about our work.
In timely and incisive analysis, our experts parse the latest development news and devise practical solutions to new and emerging challenges. Our events convene the top thinkers and doers in global development.
The FORMA team believes that access to information is crucial for good decision making, whether at the international, national or local level. This holds as much for environmental issues as it does to more traditional development issues, and it is with this in mind that the FORMA system was envisioned and developed. Every piece of data we used to build FORMA was downloaded for free, and anyone can use the same data to verify or improve upon our methods.
You can download the FORMA output file on this page for February 2000 to October 2009, which represents the distillation of hundreds of gigabytes of data into one small database for Indonesia. You will also find descriptions of and links to each of the input data sets, available from government and academic institutions around the world.
As we refine our data processing methods and consolidate the different scripting languages we use, we plan to release the source code for the FORMA system. If you would like to be notified when we do so, please follow the link below.
