How Much Dark Data Exists?

The volume of dark data can be overwhelming. Consider these statistics:

A typical child welfare case file contains over 1,000 documents; approximately 4,000–5,000 pages of information.i

An estimated 80% of case content resides in an unstructured format called "dark data."

The average caseload is between 24 and 31 cases.ii

Due to the sheer volume, breadth, and complexity of a case file, it can take a child welfare worker upwards of 12 hours to review the history of just one case.iii
