Case Analytics and the Criminal Justice System: A Look at Tarrant County

Case analytics are big business in the world of civil litigation. They help lawyers understand what cases are worth, what motions a given judge is most likely to grant, and what juries are doing in a specific jurisdiction. While each case is unique, this data helps shape litigation strategy, manage client expectations, and even provide insight into opposing counsel.

This type of analysis is largely absent in the criminal arena, although there are some promising efforts underway at the federal level. We decided to take a deep dive into case analytics using Tarrant County as an example. We relied on information obtained through Public Information Act requests and publicly available sources including the Texas Indigent Defense Commission and the Office of Court Administration.

Our models can be easily applied to any county in the state, as well as statewide. Some of the information, such as how successful individual prosecutors have been, has been reserved for members of the local criminal bar association.

Tarrant County as an Example

We analyzed 203,866 criminal cases filed in Tarrant County over the last five years, from January 2014 through December 2018. Here’s what we learned.

Tarrant County’s Population is up 6%

As a starting point, we looked at the change in population in Tarrant County. More than 2.054 million people live in Tarrant County – an increase of 6 percent since 2014. The most populous city in Tarrant County is Fort Worth, which is the county seat and also where the Tim Curry Criminal Justice Center is located.

Criminal Case Filings are up 16% since 2014

Based on data maintained by the Office of Court Administration, over the past five years, the number of cases filed with the Tarrant County Criminal District Attorney’s Office has increased 16 percent. In 2018, 46,099 cases were filed, compared with 39,579 in 2014.


Tarrant County criminal case filings are up 16% since 2014.

Of the 46,099 cases filed in 2018 in Tarrant County, 28,695 were misdemeanors and 17,404 were felonies.


Misdemeanor case filings dropped in 2015, which was the first year of the current administration. In 2018, the misdemeanor filings returned to 2014 levels.


Felony cases also initially dropped but have been on the rise since 2015.

Tarrant County District Attorney’s Budget is up 14 Percent

Since 2014, the District Attorney’s Office Budget has increased by 14 percent (using actual expenditures for 2014, 2015, 2016, 2017 and appropriations for 2018). In 2018, the District Attorney’s approved budget was about $41 million.

Resolutions through Pleas Trending Downward

Despite the increased number of case filings, fewer cases are being resolved through plea bargain agreements. For example, in 2014, for every 100 felony cases added to the dockets, 71 were resolved by pleas. Since 2014, the number of pleas have not increased in step with the number of cases filed. In 2018, only 58 pleas were secured for every 100 felony cases added to the docket.

Plea bargains are a way for cases to be resolved expeditiously, thereby generally maintaining or reducing the load for the court. When cases aren’t disposed through plea bargain negotiations and they sit on the docket, it increases the courts backlog of unresolved cases and strains resources.


While the budget and case filings have gone up, fewer cases are being resolved through pleas.

Case Resolutions Overall are Down

For case resolutions, we included dismissals with the number of cases pled. In 2014, there were 99 felony cases resolved for every 100 cases filed. By 2018, that had dropped to 84 felony cases resolved for every 100 felony cases filed.


Including dismissals, cases were resolved at a 1:1 ratio in 2014. By 2018, more cases were being filed than resolved.

The rate of pleas in misdemeanor courts have also dropped. For every 100 misdemeanor cases filed in 2014, there were 85 misdemeanor pleas. For every 100 misdemeanor cases filed in 2018, there were 66 pleas.

In the past, misdemeanor case resolutions (pleas and dismissals) exceeded case filings. Over the last three years, far more cases have been filed than have been resolved. The difference between the number of cases being filed and the number of cases being resolved went up in 2016, 2017, and 2018.


Misdemeanor cases are being filed and accepted by the District Attorney’s Office at a much greater rate than they are being resolved in Tarrant County.

The number of misdemeanor cases more than 90 days old at the time of resolution went from 15,054 in 2014 to 17,113 in 2018 – an increase of 14 percent.


The number of misdemeanor cases that were more than 90 days old at the time of resolution hit an all-time high in 2018 in Tarrant County.

The rise in case filings was slower for misdemeanors than it was for felonies between 2014 and 2018 in Tarrant County. While case filings went up overall by 14 percent, the case filings for felonies went up by 30 percent.


In 2014, 78 percent of felony cases were being resolved within 90 days. In 2018, that number dropped to 64 percent.

However, the number of cases that were more than a year old when resolved has decreased slightly. In 2014, 934 felony cases were over a year old when disposed, compared to 823 in 2018.  The decrease in overall case resolutions ultimately affects taxpayers, who pick up the tab for new courts, new judges, more prosecutors, pre-trial bond supervision, and pre-trial incarceration.

Decline in Experienced Prosecutors

Unique to criminal case analytics is the ability to quickly gauge the overall experience level for any given prosecutor’s office in Texas. In 2001, Texas lawmakers implemented longevity pay for attorneys who have served as criminal prosecutors for more than five years. Longevity pay increases each year until it reaches a cap act the 21st year of service. Each year, millions of dollars flow from the state coffers to local district attorneys offices as District Attorney Longevity Pay Reimbursements. The more experienced the prosecutors are, the more each county collects in reimbursements. The District Attorney Longevity Reimbursement for Tarrant County has dropped each year since 2014 (when it was $424,570) to 2018 (when it was $299,630).


Tarrant County Court Appointments on the Rise

The Office of Court Administration reports that there has been a 140 percent increase since 2014 in Tarrant County in the number of cases in which courts appoint attorneys. Between 2014 and 2017 (the last year expenditures are currently available) the cost of court-appointed counsel in Tarrant County has only gone up 14 percent.
