✅ The CPF version 2.0 encompasses up to 43 waves (between 1968 and 2024), combines data from seven countries, and comprises approximately 3 million observations from more than 400,000 respondents.

✅ The LISS panel from the Netherlands was added, offering high-quality annual data across diverse life domains. This was done in collaboration with Priscilla Zhang from Centrdata (the authors of the LISS survey).

❌ The Russian part of the project (RLMS) has been excluded from CPF v2.0 in response to Russia’s 2022 invasion of Ukraine. See the note here

✅ The code was adjusted to include the latest available waves (data collected up to 2023 and 2024)

✅ The CPF code was improved with a more transparent syntax structure and some modifications to the harmonization code (based on the team evaluation and users’ suggestions). T

The development of this version was supported by a grant from the NWO (The Dutch Research Council) Open Science Fund (grant ID OSF23.2.017).
