Overview

The Bureau of Justice Statistics (BJS), in partnership with the Federal Bureau of Investigation's (FBI) Criminal Justice Information Systems (CJIS), is spearheading the National Crime Statistics Exchange (NCS-X), a program designed to generate nationally-representative incident-based data on crimes reported to law enforcement agencies. NCS-X will leverage the FBI's existing National Incident-Based Reporting System (NIBRS) by recruiting a sample of 400 law enforcement agencies to supplement the existing NIBRS data by providing their incident data to their state (or the federal) NIBRS data collection program. When data from these 400 agencies are combined with data from the more than 6,600 agencies that currently report NIBRS data to the FBI, NIBRS will be able to produce national estimates of crime that can be disaggregated by victim-offender characteristics, the circumstances of the event, victim-offender relationship, and other important elements of criminal events. When completed, nationally representative NIBRS data will increase our nation's ability to monitor, respond to, and prevent crime by allowing NIBRS to produce timely, detailed, and accurate national measures of crime incidents

BJS needs the support of the law enforcement community to ensure the NCS-X is successful. NCS-X is designed to implement efficient and minimally burdensome processes to collect and extract incident-based data from existing records management systems. NCS-X provides technical assistance and funding to the sampled 400 law enforcement agencies and to state Uniform Crime Reporting (UCR)/NIBRS programs to enable them to report incident-based crime data to the FBI. A team of partner organizations—including RTI International, the International Association of Chiefs of Police (IACP), the Police Executive Research Forum (PERF), the Integrated Justice Information Systems (IJIS) Institute, and the National Consortium for Justice Information and Statistics (SEARCH)—is working with BJS and FBI CJIS to implement the NCS-X initiative. This includes coordinating efforts with local law enforcement, state UCR Programs, the law enforcement technology industry, and other key stakeholders. An NCS-X Executive Steering Committee has been established to review possible design and implementation options to ensure the maximum benefit to both participants and key stakeholders.

RESOURCES FOR STATE AND LOCAL AGENCIES

BJS, FBI's CJIS, and the NCS-X Implementation Team have developed a suite of materials designed to assist state UCR Programs and local law enforcement agencies to transition to incident-based reporting (IBR).

NIBRS Pre-Certification Tool (PCT) New

The PCT provides law enforcement agencies, responsible for submitting Incident-Based Reports (IBR) data to State Uniform Crime Reporting (UCR) programs, the ability to test their submissions in advance of its formal delivery. State UCR programs may also use the NIBRS PCT to test their IBR submissions before beginning the NIBRS certification process with the FBI. The NIBRS PCT exercises the NIBRS data edit and validation rules and provides formatted output of errors, so that submitters may correct their data submissions and, ultimately, speed the FBI CJIS and/or state IBR certification process.

NCS-X Sample

Currently more than 6,600 agencies report their crime data to the FBI via NIBRS. Presently, NIBRS participants consist primarily of agencies that serve cities with fewer than 250,000 residents. It was determined that if a sample of 400 law enforcement agencies would agree to become new NIBRS participants, then data from these agencies, in combination with data from current NIBRS participants, could be used to generate statistically sound and detailed national estimates of crime known to law enforcement.

The NCS-X sample of 400 law enforcement (LE) agencies is a stratified random sample consisting of 12 strata based on the government type of the LE agency (i.e., state, county or township, municipal, or tribal) and number of sworn officers. The sample of 400 agencies was drawn from the set of agencies not reporting NIBRS data for 2011 and stratified based on agency type and agency-level sworn officer counts. The strata break down as follows:


NCS-X sample strata description and size of agencies

Stratum 1

2011 NIBRS participants

Strata 2 through 12

Non-NIBRS agencies in 2011

Stratum 2

Agencies with 750 officers or more (any agency type)

Stratum 3

State agencies with 1-749 officers

Stratum 4

State or municipal agencies with official officer count of zero

Stratum 5

County or township agencies with 36-749 officers

Stratum 6

County or township agencies with 0-35 officers

Stratum 7

Municipal agencies with 181-749 officers

Stratum 8

Municipal agencies with 61-180 officers

Stratum 9

Municipal agencies with 16-60 officers

Stratum 10

Municipal agencies with 1-15 officers

Stratum 11

Remaining nontribal agencies (any type and size)

Stratum 12

Tribal agencies

Stratum 2 agencies were selected with certainty, while strata 3 through 12 agencies were selected with varying probabilities of selection. In total, the sample is comprised of 72 certainty agencies (from stratum 2), 319 probability agencies (from strata 3 through 11), and 9 tribal agencies (from stratum 12). The number of NCS-X sample agencies by state are available in the sample of 400 law enforcement agencies.

Project Status

A 2013 joint statement issued by the FBI and BJS marked the launch of NCS-X. During 2013, BJS has worked to build partnerships and support for the project and to construct the NCS-X sampling frame.

In 2014, NCS-X activities were focused on assessing the viability and costs of the project. Tasks included (1) recruiting the selected sample of 400 law enforcement agencies for participation in NIBRS, (2) reaching out to stakeholders and existing state UCR/NIBRS reporting programs to gain their insight and support, (3) developing cost and feasibility guidelines for NCS-X implementation, and (4) identifying barriers and developing incentives and resources to encourage candidate agencies to participate in NCS-X.

In FY 2015 and FY 2016, BJS awarded nearly $13 million through the NCS-X Phase 1 and Phase 2 solicitations to support NIBRS efforts among state UCR Programs. Award decisions were made in coordination with the FBI, with funding provided to 21 states over the two fiscal years—Alabama, California, Florida, Hawaii, Illinois, Kansas, Louisiana, Maine, Maryland, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New York, Oklahoma, Pennsylvania, Utah, Washington, Wisconsin, and Wyoming. Also the FY2016 supplemental award funds of just over half a million dollars were provided to several Phase I grantees to expand the scope of their NIBRS implementation efforts. Additional information about current NCS-X funding to state UCR Programs is included below.

In addition to the 21 states that received an NCS-X planning or implementation award, four states have begun their own state-funded and state-led effort to establish a NIBRS program.1 Twenty states are considered ineligible for NCS-X funding under this solicitation, as they each have a certified NIBRS state reporting program to which more than 80% of law enforcement agencies in the state report. The remaining four states—Alaska, Arizona, Mississippi, and New Mexico—have not received NCS-X funding to date.

1Texas and Oregon are already certified to report NIBRS data to the FBI's UCR Program. Both states are working to expand the number of local LE agencies reporting IBR data to the state. The state-led efforts in Georgia and Indiana are to establish a certified NIBRS program within their respective state UCR Programs. The NCS-X sample agencies in all four states are still eligible for funding support and technical assistance through the NCS-X Initiative.

As of June 2017, the NCS-X Initiative has successfully convened grant projects with all but four of the eligible state UCR Programs (i.e., Alaska, Arizona, Mississippi, and New Mexico; Mississippi does not currently have a state-level UCR Program). In addition, approximately half of the largest LE agencies in the sample (those with 750 or more sworn officers) have been recruited and are actively working on their transition to NIBRS reporting, including 17 agencies that received direct NCS-X funding in FY2016.
