Texas Jail Data
INSIGHT PROJECT
INSIGHT PROJECT
Our mission: We work collaboratively with jails and partner organizations to gather, process, and interpret data in order to support informed, data-driven improvements in detention environments.
We maintain an objective, data-driven approach. We do not engage in advocacy activities.
Over the last 2918 days (since 12/23/25), we have used public data to identify:
110 Dallas County inmates sentenced to State Jail or Prison who appear to have been released from Dallas County Jail after their sentence end date.
The median overstay for these inmates is 10 days.
1,497 combined days of apparent overstay.
2 inmates sentenced to State Jail or Prison who appear to be currently incarcerated in Dallas County Jail beyond their sentence end date (one inmate is currently 30 days over) .
58 Dallas County inmates sentenced to State Jail or Prison who were released on time.
When we find a probable overstay, we send the inmate's information to Dallas County with an escalation request for review and release of the inmate. Sometimes it is already in process.
Overstays cost Dallas County jail $98.26/day (the jail does not benefit financially from overstays).
Because we use only public data, this is best-effort. The quantity of our data collection has increased each month. Dallas County does not provide data, so the above reflects only what we find manually.
To verify whether indigent defendants in a Texas county were receiving public defenders or court-assigned attorneys in the correct proportion, we reviewed 1,310 cases on behalf of a legal nonprofit and created a data set for them.
Our founder completed this project before TJDIP was formed.
Policymakers, legal professionals, journalists, incarceration professionals and community organizations) who want to make positive changes in incarceration sometimes need of data sets to analyze.
But they don't have the luxury of having someone to gather this data. That's where we come in.
The incarceration industry does not have sophisticated technology. Therefore, most of what we do requires a lot of manual effort. Go to a site, click here, cut-and-paste into a spreadsheet, categorize the info, repeat.
We are glad to do this gruntwork at no charge so that others can make improvements in incarceration. Please reach out if you need this help.
