Ohio Longitudinal Data Archive

The OLDA data repository, an example of Big Data, is a powerful resource comprised of public administrative records for millions of Ohio residents.

The repository is managed by CHRR for several State of Ohio agencies and offers researchers a unique opportunity to analyze the education, work, and training experiences of Ohioans over time. Data access is allowed under restricted conditions to protect the privacy of the records contained in the repository.
