Personnel data are available in two formats:

1. Summarized demographic information across all records.
2. Time-Series of demographic information as provided by Defense Medical Surveillance System (DMSS) synchronization

Summarized demographic information includes variables such as the highest education level attained, the total number of days served in the military, and the first known values when either enlistment was prior to 1990 or when it was missing on their first record.

For each dataset, a Data Dictionary that describes the data is publicly available. In order to obtain the actual data in SAS or CSV format, you must begin a new MACS project. Data will be delivered once the project is approved and data transfer agreements are completed. A justification must be provided in the IRB Proposal for each data category as grouped in the data dictionary, showing how it supports the aims of the request.
