The Structure group of the Analyst Resource Center periodically reviews the structure of the WID, and makes modifications when they feel it is appropriate to do so. When modifications occur, a new version of the WID is created. While states are required to update their WID to the latest version, we realize that the transition to newer versions can take time. Therefore, the ARC will maintain documentation and provide support for the current and past two versions of the WID. Below you will find links to the file structure, file information and data directories.
| Version 2.7 | Structure | File Info | Directories |

These files contain data at different levels of geography. Some state files also contain data for counties, statistical areas or other sub-state regions.
| National | Files | Information |
Each state’s directory contains data files specifically developed for their state. Information is taken from the Department of Commerce (BEA Income, Census population estimates), Labor (apprenticeship program completions), Defense (military separations by related civilian occupation) and others. The data files contain national and state data or estimates. Many also contain information for counties or other statistical areas.
