The data of the Index is available for use under a public domain data license. We provide the data as a single archive, and as indivdual files in CSV and JSON formats (as part of the API).

A lot of work goes into preparing the Index each year, and we are eager to get feedback on how you use the data, so please do help us with this by filling out the form below.
