Important Notice: CRSP US Stock & Indexes Databases Flat File Format 2.0 (CIZ)

As communicated previously, CRSP has migrated to a new back office and introduced the Stock & Indexes Flat File Format 2.0 (CIZ) in the summer of 2022. Subscribers are required to migrate to CIZ, as the December 2024 data which was released in January 2025, was the last release of datasets produced in the Legacy (FIZ) and Flat File Format 1.0 (SIZ) formats.

Additional reference materials and resources can be found in the Documents & Resources section of the CRSP US Stock Databases landing page.

CRSP Access

The December 2024 data cut that was released in January 2025 was the last release of files for CRSPAccess.
