Overall youth crime declined from a high of 9,457 incidents in 2006 to 7,101 incidents in 2009, according to the more recently available data from the Boston Police Department. This decline was largely due to a decrease in Part 2, or quality of life, crimes committed by youth in Boston as the total number of violent and property crimes committed by those under 24 remained at about 3,000 incidents. The decline was also driven by a falling number of incidents involving very young youth under the age of 16.
Additionally, the percent of teens in Boston who reported carrying a gun within the previous month continued to fall to just 3.3% in 2011 compared to 10% of teens in 1993. The racial/ethnic gap has all but closed when it comes to carrying weapons: 3.9% of African Americans, 3.5% of white and 2.8% of Latinos reported carrying a gun in 2011 compared to 15.3%, 4.7% and 9.6%, respectively, in 1993.
