Presentation on theme: "Offender Population Forecasting in Virginia. 2 Background - Studies by JLARC in 1980s Staff of the Joint Legislative Audit & Review Commission (JLARC)"— Presentation transcript:
2 Background - Studies by JLARC in 1980s Staff of the Joint Legislative Audit & Review Commission (JLARC) first reviewed the Department of Corrections’ (DOC) forecasting procedures in 1985 and reported weaknesses in the methods used by DOC to forecast the inmate population. A 1987 JLARC report recommended changing the forecasting process toward a more open, participative process. “The process for producing and validating the forecasts should be expanded to include more participants. Such a process would ensure that key actors in the criminal justice system have input into the forecast. Moreover, such a group would promote general understanding of the forecast and the assumptions which drive it.” Source: An Overview of Expenditure Forecasting in Four Major State Programs, JLARC (2000)
3 Background - Consensus Forecasting A more open, participative forecasting process was implemented in the late 1980s and remains in use today. This process is known as “consensus” forecasting. The Secretary of Public Safety oversees this annual process.
5 Committee Structure Technical Advisory Committee Members include personnel from various state agencies who have expertise in statistical and quantitative methods. Technical/Policy Liaison Work Group Members include staff of House Appropriations and Senate Finance Committees as well as agency deputy directors and senior managers. Policy Advisory Committee Members include policy makers and other decision makers who administer the criminal justice system.

8 Four Inmate Population Forecasts Produced State-responsible (SR) inmate population Population housed in DOC prison facilities State-responsible inmates housed in jails Local-responsible (LR) prisoner population Prisoners confined in local and regional jails (excluding state and federal prisoners) Juvenile correctional center (JCC) population Juvenile detention home (JDH) population
9 Technical Advisory Committee Two analysts from two different agencies work independently to develop competing forecast models. Confidence in the official forecast is bolstered if the different methods used by the two agencies converge on the same future population levels. The Technical Committee scrutinizes each forecast according to the highest statistical standards. The forecasts with the best set of statistical properties are recommended to the Liaison Work Group. The Technical Committee also examines trends in reported crimes, arrests, court caseloads, etc., and provides this information to the Liaison Work Group and Policy Committee.
10 Technical-Policy Liaison Work Group The Work Group reviews the projections proposed by the Technical Committee. The Work Group can request additional data or analysis as needed. The Work Group selects which forecasts the Policy Committee should consider.
11 Policy Advisory Committee The Policy Committee reviews the projections and selects a forecast for each population. This Committee also considers the effects of recent trend shifts and newly adopted legislation. The committee can approve adjustments to the forecast to account for the impact of such changes, as it deems appropriate.

The growth and decline in the case backlog was due primarily to drug cases. Between FY03 and FY06, the drug case backlog increased 371%, while the backlog for all other cases combined increased 30%. Between FY06 and FY08, the drug case backlog decreased by 90%, while the backlog for all other cases combined decreased 30%.

Source: Compensation Board (August 21, 2008) December 2007 The number of defendants in jail awaiting trial on felony charges peaked in September 2006.
