Shelly,

Here are my responses to the CSLLEA passback.

Thanks,

Brian

 

Q1a. Please more clearly distinguish the contribution of the CSLLEA, particularly at its current periodicity. 

 

Unlike the Uniform Crime Reports (UCR) and Census of Governments (COG), the CSLLEA provides an opportunity to collect additional data to supplement the basic personnel counts. This includes a breakdown of agency functions, and how both sworn and civilian personnel are allocated to functions such as patrol, investigations, court security, process serving, and jail operations.  As is planned for the 2008 data collection, data that provide some context to the trends observed in personnel counts can also be included.  Examples of this include questions related to recruitment and retention.

 

Q1b. What are the major scope and methodological differences between the law enforcement employment counts in CSLLEA and the Census Bureau�s quinquennial Census of Governments?

 

The annual counts of sworn personnel in the UCR and COG (as well as the Expenditure and Employment (E & E) sample survey based on the COG), like those from the CSLLEA, include only full-time employees with arrest powers. However, the CSLLEA includes all officers with arrest powers regardless of function, while the UCR data exclude officers not paid out of police funds. This generally excludes employees working for jails or courts. A similar exclusion is found in the sample data from the Census Bureau's Annual Survey of Public Employment published by BJS in the E & E series. E & E categorizes justice system employees by function: police protection, judicial and legal, or corrections.

 

Q1c. How similar are the estimates over time?

 

Generally the employment trends reported by the CSLLEA, UCR, and the COG/E & E have been similar over time. However, the UCR and COG/E & E totals have been consistently lower than those generated by the CSLLEA. For example, in 2004, the CSLLEA reported 1,076,897 full-time personnel employed by law enforcement agencies, compared to 970,588 for the UCR, and 892,436 for the E and E. Counts are also higher for full-time sworn personnel, with a CSLLEA total of 731,903 compared to 675,734 for the UCR and 688,909 for the E and E.

Another reason the UCR counts are lower than those from the CSLLEA is that the UCR excludes some agencies that do not have an Originating Agency Identification (ORI) num­ber assigned by the FBI. Some agencies without an ORI are still included in the UCR employee counts (but not in the agency counts), because they report their data to another agency which in turn reports it to the FBI. Overall, the UCR data cover 95% of the U.S. population.

 

Q1d. How suitable would the Census of Governments be to serve as a sampling frame for LEMAS?

 

A major limitation of the COG for use as a sampling frame for LEMAS is that it is a government-based survey whereas the CSLLEA and LEMAS are agency-based.  The government offices surveyed in the COG would not be an appropriate contact list for the broader data sought from the State police, local police, sheriffs� offices, and other law enforcement agencies responding to the CSLLEA. 

A sampling procedure based on the COG would also be limited due to the existence of multiple agencies within a single government�s budget. For example a State government�s employment totals for police protection might include the State Highway Patrol, State Park Police, and numerous State university and college police.  This complicates the development of an agency sample. The converse is also true where a single agency serves across jurisdictional boundaries such as a transit or airport authority police department.

 

2.  Please clarify who the current CSLLEA collection agent is and whether it is a grant-funded collection, as indicated in A14.

 

The current cooperative agreement award for the 2008 CSLLEA is with the National Opinion Research Center (NORC) at the University of Chicago in the amount of approximately $806,000.
