Youth Dangerousness Hearings Data Trends
If a youth is charged with a specific offense listed in Massachusetts' law (Chapter 276, Sec. 58A) and the assistant district attorney (ADA) thinks the youth is dangerous, the ADA can ask the court to hold the youth without bail (no money or conditions set). If this happens, a hearing must be scheduled within three days. These hearings are called "Dangerousness Hearings," or are sometimes referred to as "58A hearings" due to the section of law that mandates them.
At a Dangerousness Hearing, youth are represented by an attorney and they have the same rights as they would in a trial. At this hearing, the judge may consider the circumstances of the charge the youth is accused of committing, any potential danger posed by the youth's release, and other factors such as the youth's mental or behavioral health and substance use.
If the judge finds by clear and convincing evidence that there are no terms (called "conditions") the youth can follow that would reasonably assure the safety of an individual or the public if the youth were to be released, the judge can hold the youth in detention without the possibility of bail until the trial. If a judge finds the youth can be released on conditions, the youth is released with conditions to follow.
Youth Dangerousness Hearings Data: Demographic and Geographic Breakdowns
[Demographic data breakdowns for youth with dangerousness hearings will be available in the future.]
Below, select a county to see how many dangerousness hearings were held that year or use the drop down menu to see the change in number of hearings from the previous year. You can also use the drop down menu to view the number of dangerousness hearings in each court county per 10,000 youth (ages 12-17) in that county. To change the year, select the fiscal year from the drop down menu.
Youth Pretrial Supervision Data Trends
After being arraigned, but before going to trial, a youth may be placed on pretrial supervision. The youth must report to a probation officer and follow rules set by the court. Some potential rules include wearing a GPS monitor, abiding by a curfew and staying away from certain people/places. If a youth violate these rules, the prosecutor can ask a judge to hold the youth in detention until their trial.
The visualization below shows the number of pretrial supervision cases since FY15. Use the drop down menu to view the number of monthly cases across the state or select a court county.
Youth Pretrial Detention Data Trends
Detention occurs when a judge has placed a youth in the custody of the Department of Youth Services (DYS) before their trial. This occurs after a youth has been arrested and arraigned. A youth is placed in detention if:
- a judge has set bail, but the youth is unable to pay the bail amount or meet the bail conditions of release
- a judge has determined a youth is too dangerous to be released (following a 58A dangerousness hearing)
A youth can also be placed in detention following a violation of probation. Detention stays can last from a couple of hours to weeks or months depending on a variety of factors.
Data on bail determinations is not currently available.
Youth Pretrial Detention Data: Demographic and Geographic Breakdowns
"Demographics of detention admissions", below, shows new detention admissions and the demographics of youth who are detained over time. From the drop down menu, you can select a demographic variable (race/ethnicity, gender, or age) of interest and see the breakdown of that variable in youth detention admissions over time.
You can also look at data by calendar year or fiscal year, and look at either the total number of detention admissions in a given category, or the percent change in detention admissions in that category year over year.
As a point of comparison, this page also includes a visualization showing the racial distribution for all Massachusetts youth (not just those in the juvenile justice system) based on U.S. Census data.
The visualization below shows changes in the total number of youth who are detained in a given year, as well as demographic breakdowns (race/ethnicity or gender). This is called the DYS annual detention caseload.
Below, select a county to see how many detention admissions occurred that year or to see the percent change in admissions from the previous year. You can also select to view the number of detention admissions in each court county per 10,000 youth (ages 12-17) in that county. To change the year, select the option from the drop-down menu.
The first visualization shows where youth reside (home county). The second shows where a youth was arrested (sending county). Sending county data is unavailable for 2021.
Youth Pretrial Detention Data: Offense Type and Severity
The visualizations below show what types of offenses youth were detained for, and how that has changed over time. You can also look at data by calendar year or fiscal year, and look at either the total number of detention admissions in a given category, or the percent change in detention admissions in that category year over year.
The Department of Youth Services categorizes the seriousness of offense by “grid level.” This is a numeric representation ranging from 1 (least serious) to 7 (most serious), based on the adult sentencing guidelines.
Examples of common offense types for each grid level include:
1- Disturbing the peace, Petty larceny, Possession of marijuana
2- Possession of cocaine, Assault and battery
3- Breaking and entering (felony), Larceny (felony)
4- Assault and battery with a dangerous weapon, Armed robbery
5-Armed assault and robbery, Attempted murder
6- Car jacking with a firearm
The next visualization indicates the MSO Grid Level for new detention admissions.

58A Hearing "dangerousness hearing": If a youth is charged with a specific offense listed in Massachusetts General Laws chapter 276, Section 58A, and the District Attorney believes the youth would pose too great a danger to the public to release pretrial, the District Attorney can ask the court to hold the child without bail.

Bail: Money deposited to release the arrested person from custody. The purpose of bail is to make sure that the defendant will appear for all court dates.
Birth sex: DYS reports with the following options: Male or Female. Youth are asked to self-identify.
Calendar year: From January 1 through December 31 of the year listed.
Fiscal year: From July 1 through June 30 of the year listed.
The Trial Court reports race and ethnicity data with the following categories: White, Black or African-American, Hispanic/Latinx and Other. The Other category is a consolidation of American Indian or Alaska Native, Asian, Native Hawaiian or other Pacific Islander, Other, and Multirace, due to low case numbers in these groups. Youth are asked to self-identify.
Probation reports with the following options: American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Pacific Islander, Other or Mixed Race, and white. Ethnicity is defined as: Hispanic or Latino, Non-Hispanic/Latino, or Not known/Not reported.
DYS reports with the following options: American Indian or Alaska Native, Asian, Black or African American, Chooses not to self-identify, Native Hawaiian or other Pacific Islander, White, Multiracial (if more than one selected). Ethnicity is self-reported – “Yes” or “No”— as Hispanic. Youth are asked to self-identify.
Due to the small numbers of youth, individuals in the following race categories are reported in "Other" in these visualizations: American Indian or Alaskan Native, Asian, Native Hawaiian or Other Pacific Islander, and Unknown race categories.
