Juvenile Crime vs. Adult Crime• In studying Juvenile Crime we attempt to pick at risk
youth and address the “risk” and “protective” factors that impact individual youth• Effective programs are expensive and address cognitive and
behavioral change at the individual and familial level• Individual level information can also be used to assess
networks of juveniles engaged in criminal behavior
• Challenges with model:• Cost of treating individuals• Labeling youth as “criminal” or “at risk” can create other issues• Effective targeting of resources to address needs
![Page 4: Incidents of Juvenile Arrests January 2009 - May 2014.](https://reader031.fdocuments.us/reader031/viewer/2022020102/56649eca5503460f94bd7d21/html5/thumbnails/4.jpg)
Point Pattern Analysis• Takes all these points (kernel)
and maps them into positions based on the closeness of these incidents (KDE)• Measures the density or
closeness of the same criminal event• Provides cross-sectional
rendering of crime events• Rendering includes several
streets and statistical “white noise”
![Page 5: Incidents of Juvenile Arrests January 2009 - May 2014.](https://reader031.fdocuments.us/reader031/viewer/2022020102/56649eca5503460f94bd7d21/html5/thumbnails/5.jpg)
Street Segment Analysis• Maps event to the nearest street• Uses a density function LISA (Local Indicator of Spatial
Autocorrelation) • Provides a statistical measure of street segments where
crime cluster high• We then look to each individual street segment which are
separated by one segment. This gives us street segment clusters.• Then we can examine each of these street segments, based
on the crime and the physical environment, see what factors might be contributing to crime• We can also then measure the change in these cluster over
time

• Identified 126 Street Segments
• Segments make up 3.6% of Trenton's geographic space
• 48.7% all juvenile arrests occurred within one block of these areas
• 63.3% all juvenile arrests occurred within two blocks of these areas
![Page 8: Incidents of Juvenile Arrests January 2009 - May 2014.](https://reader031.fdocuments.us/reader031/viewer/2022020102/56649eca5503460f94bd7d21/html5/thumbnails/8.jpg)
Examined each set of street clusters
• Looked for interconnection of streets
• Examined if the event was acute or chronic (time and prevalence)
• Looked at crimes within one standard block (330 feet) of these street segments
• We will examine the crime typology and the discuss how to best address the crime

Area 2• Predominantly drug related offenses
• More variety in type of criminal activity
• Mostly black males• Both time lines show general increase in juvenile crimes in 2011
– drop off beginning June 2012• It appears that efforts in Area 1 pushed delinquency into Area 2• We need more data to see if crime in Area 2 was disbursed or moved
• Different timeline than Area• Morning crimes• Afternoon crime (related to property crimes)• Evening crimes (related to drug markets)
• Late onset delinquency related to drug use

Area 5: Top Five Juvenile Arrests

Area 5• Predominantly drug use and related crimes• Mostly among black males• Stable drug market• Activity occurred throughout the day• Late onset delinquency
![Page 45: Incidents of Juvenile Arrests January 2009 - May 2014.](https://reader031.fdocuments.us/reader031/viewer/2022020102/56649eca5503460f94bd7d21/html5/thumbnails/45.jpg)
Overall analysis• Overall it appears that the serious juvenile crime is
spurred by drug markets• This began in 2009 and has moved around the city in an
overall upward swing• It appears that older juveniles are being incorporated into
current drug markets • Older juveniles appear to be used to transport illicit merchandise
• Juveniles are also arming themselves for protection• Juveniles appear to be reacting effectively to law
enforcement responses by moving around the city

Overall analysis• Arrest of this population has been found to be the worst
response• Most of the factors with regard to late onset have much
more to do with peer-group, labeling, and family dynamics• If we are going to intervene we need to do it in late-middle
or early-high school• We need consistent effort target at this population because
we are generally competing with the gangs• From the Trenton adult data this age becomes the launching
point where individuals begin to engage in more serious crime
