As part of this project, we are pleased to announce that we are making data from the Facebook Ad Library available to the broader academic community for the first time, for projects concerning the effect of social media on elections and democracy. The Ad Library API includes data on political advertising. The Ad Library is new and under active development, and we are hopeful Facebook will continually improve its capabilities so researchers can better analyze campaign spending, ad targeting, and ad content. It includes information about $539,861,997 spent on 3,259,272 ads in the US since May 2018; it also includes somewhat smaller numbers of ads in India, the UK, Ukraine, and Brazil.
