Over the last five years the number of police stops and arrests involving Capital Region youths has fallen more than 45 percent, according to state data. It's a stunning drop -- but one without a clear single reason, say law enforcement and juvenile justice system professionals. Several factors are likely in play, including an overall drop in crime in the country, changes in the drug trade, increased use of alternatives to incarceration and changes in youth culture, said Jeffrey Butts, director of the Research and Evaluation Center at John Jay College of Criminal Justice. “I’ve been doing this for a long time, tracking trends, and something definitely feels different than it did 20 years ago,” Butts said.
Based on the latest statistics compiled by the Federal Bureau of Investigation (FBI), the national violent crime arrest rate declined 38 percent overall between 1988 and 2018, but the steepest declines were observed among youth ages 10 to 14 (–53%) and 15 to 17 (–54%). The arrest rate for 18-20 year-olds dropped 47 percent while the arrest rates for adults ages 21-24 and 25-49 declined 42 percent and 23 percent, respectively.
The decline in possession of weapons at school and in the prevalence of weapon-related threats in schools also holds true for overall juvenile crime, according to Jeffrey Butts, director of the Research and Evaluation Center at the John Jay College of Criminal Justice in New York City. “One popular theory is that the drug trade was much more dangerous 30 years ago. Kids that lived in neighborhoods with active drug sales going on often felt that they needed to have a gun on them to protect themselves,” he said. “The daily threat from street-corner drug sales has gone way down.”
Was the presence of the MAP initiative in some NYCHA developments associated with greater improvements in crime and victimization outcomes compared with the same outcomes in NYCHA developments not involved in MAP? The results presented here do not answer the question in full, but they offer an early look at efforts by the research team to generate more precise answers. Additional analyses are needed to rule out competing explanations and to examine the complex series of relationships among all the study’s variables. Based on the preliminary findings in this report, however, the results of MAP to date may be considered promising.
This second in a series of reports about the evaluation of the New York City Mayor’s Action Plan for Neighborhood Safety (MAP). This Evaluation Update: summarizes the goals and methods used to evaluate the Mayor’s Action Plan; describes the quasi-experimental design used to test the outcomes and impacts of MAP as well as the data sources assembled by the research team and how they are used; and portrays a logical framework the research team used initially to identify causal pathways through which various elements of MAP were intended to achieve their desired effect.
In 1993, a peak year for violent crime, police agencies nationwide reported about 13 under-age-18 murder arrests for every 100,000 youth ages 10 to 17. The youth arrest rate for murder dropped 79 percent between 1993 and 2017.
To evaluate the New York City Mayor’s Action Plan for Neighborhood Safety (MAP), an initiative to improve the safety of public housing developments, researchers estimated the counterfactual (no intervention) by selecting a set of comparison housing developments not involved in the initiative. The study relied on the statistical method known as propensity score analysis (PSA) to select the comparison group.
The John Jay College of Criminal Justice Research and Evaluation Center found that between 2014 and 2016, there was a 50 percent decrease in gun injuries in East New York, Brooklyn and a 37 percent reduction in the South Bronx, two communities where Cure Violence has been implemented.
Jeffrey Butts, director of the Research and Evaluation Center at John Jay College of Criminal Justice in New York, said that in some ways, law enforcement never has been best equipped for crunching the numbers. Go to a police department and ask to be taken to the unit that does the crime reporting. Sometimes, it’s civilians with advanced degrees and computers, he said. “Other places, you walk in and it’s full of uniforms,” he said, pointing out that some departments view crime reporting as a desk job for officers who no longer want to work patrol. At a department such as the New York City Police Department, there are civilian research analysts with doctorates.
