Carolina Botero (of CC Colombia and now CC regional manager for Latin America) has posted a brief analysis of CC license use in Latin America (es2en machine translation).
As with previous looks at CC licenses across different jurisdictions and regions, this one is based on search engine reported links to jurisdiction "ported" versions of licenses. It is great to see what researchers have done with this limited mechanism.
I am eager to explore other means of characterizing CC usage across regions and fields, and hope to provide more data that will enable researchers to do this. This will be increasingly important as we attempt to forge a universal license that does not call for porting in the same way, with version 4.0 over the coming year (as well as with the increasing importance of CC in the world).
