The Latin America Left-Leaning Populism Index, 2025 version

The first edition of the Latin American Left-Leaning Populism Index (LALLPI) is finally here! The 2025 version covers 21 Latin American countries with data spanning from 2000 to 2019.

A detailed discussion of the methodology can be found in this website’s documentation. The index’s working paper is coming out shortly.
