The CHES is a survey of national party experts to place parties on political dimensions. It is generally considered the gold standard of comparative party research.

We will compile the 1999-2024 trend file soon, but in the meantime, you can merge with 1999-2019 now. In the 2024, we added several non-CHES variables into the regular dataset (vote share, family, etc.).
