The New York State Division of Criminal Justice Services is legally authorized to gather and process data of crime from the court, law enforcement offices, prosecution and also correction agencies in the State. The data is used to create detailed statistics on crimes, dispositions and arrests. There are 13 databases with statistics along with 6 important reports that have regularly updated information on the number of index crimes per 100,000 populations for each county in NY. The data for each county is displayed by the FBI on a yearly basis. This data is based upon the U.S. Census estimates. This data is used to calculate the crime rates. Crime counts rely on official crime reports that are submitted to the Division of Criminal Justice Services via the Uni-form Crime Reporting and Incident Based Reporting programs. The so-called "index offenses" refer to violent crimes such as murder, robbery, rape, and aggravated assault, while "property crimes" include burglary, larceny, and car theft. These databases and statistics are used by both the DCJS and the FBI to see the general crime trends in the State of New York.

According to the reports published, it seems that the crime rates and also the crime volume have experienced major declines over the past decade. The 2001-2010 decade has seen a drop in the overall rate of index crimes per 100,000 residents by 21%. Also, violent crimes such as murders, rapes, robberies, and aggravated assaults have dropped by 25%. Property crimes such as burglaries, larcenies and car thefts have also dropped by 20%. It seems that the biggest drop in crime rates was for car thefts and robberies. Index crimes have dropped each year (2001-2010), though slightly rising in 2008. The number of major crimes reached the lowest levels ever in 2010. We are talking about 108,000 fewer crimes reported in 2010 as compared to the year 2001. A key point to take into consideration is that New York's population was boosted by more than 350,000 residents during the 2001-2010 decade.
But not all NY areas have witnessed the same crime reduction; the drop in index crime in New York City was greater than the one experienced in the counties placed outside NY City. These counties account for 58% of the reported crime statewide, as compared to 50% in 2000.
