Index, Violent, Property, and Firearm Rates By County: Beginning 1990

The Division of Criminal Justice Services (DCJS) collects crime reports from more than 500 New York State police and sheriffs’ departments. DCJS compiles these reports as New York’s official crime statistics and submits them to the FBI under the National Uniform Crime Reporting (UCR) Program. UCR uses standard offense definitions to count crime in localities across America regardless of variations in crime laws from state to state. In New York State, law enforcement agencies use the UCR system to report their monthly crime totals to DCJS. The UCR reporting system collects information on seven crimes classified as Index offenses which are most commonly used to gauge overall crime volume. These include the violent crimes of murder/non-negligent manslaughter, forcible rape, robbery, and aggravated assault; and the property crimes of burglary, larceny, and motor vehicle theft. Firearm counts are derived from taking the number of violent crimes which involve a firearm. Population data are provided every year by the FBI, based on US Census information. Police agencies may experience reporting problems that preclude accurate or complete reporting. The counts represent only crimes reported to the police but not total crimes that occurred. DCJS posts preliminary data in the spring and final data in the fall.

纽约州刑事司法服务部门（DCJS）从超过500个纽约州警方和郡治安官部门收集犯罪报告。DCJS将这些报告汇编成纽约州的官方犯罪统计数据，并根据国家统一犯罪报告（UCR）计划提交给联邦调查局。UCR通过采用标准犯罪定义来计数全美各地的犯罪，不受各州之间犯罪法律的差异影响。在纽约州，执法机构使用UCR系统向DCJS报告其每月的犯罪总数。UCR报告系统收集了七种被归类为指数型犯罪的犯罪信息，这些犯罪是最常用的衡量整体犯罪量的指标。这些包括谋杀/非疏忽杀人、强暴、抢劫和加重攻击等暴力犯罪；以及入室盗窃、盗窃和机动车辆盗窃等财产犯罪。枪支数量是通过计算涉及枪支的暴力犯罪数量得出的。人口数据每年由联邦调查局提供，基于美国人口普查信息。警方机构可能会遇到阻碍准确或完整报告的报送问题。所计数量仅代表向警方报告的犯罪，而不是实际发生的总犯罪数。DCJS在春季发布初步数据，在秋季发布最终数据。
