Synthetic Longitudinal Business Database (SynLBD)


The Cornell server that hosts the Synthetic Longitudinal Business Database (SynLBD) will be shutting down on September 30, 2022. We expect to be able to make the file accessible to users in another server location, and are in the process of determining where and when this will occur. In the meantime, we will not be accepting new requests to use the SynLBD. For current SynLBD users, Census staff will not accept any new validation requests after September 2, 2022. We ask that SynLBD users be mindful of constraints on staff time, and not make excessive requests of staff prior to this deadline. Requests will be processed in the order they are received and those deemed to be excessively labor intensive may be denied. Please understand that we have to balance the needs of many users. We expect to post updates about the SynLBD’s future home in the near future.

The Synthetic Longitudinal Business Database replicates the structure and statistical properties of the original confidential dataset, without using original content.
