Redeploy Illinois 2011 Annual Report - Cost Benefit Analysis


The Redeploy Illinois program saves the State far more than the $2.4 million annual appropriation. In the six years since the program's inception, participating counties sent 854 juveniles to state prisons. This is a steep decline from the projected 1,737 that were likely to have been sent to prison, based on the previous three-year trend; it represents a 51% reduction in commitments. Given the current $86,861 annual cost to keep a juvenile in a State prison, the savings to state taxpayers are considerable.

  • In the past six years since the program's inception, Redeploy Illinois sites have reduced commitments to DJJ by an average of 51%. By avoiding commitments to a projected 886 youth in Redeploy counties, the State has averted more than $40 million in incarceration costs.

In Fiscal Year 2005, when the program began, the per capita cost for a 12-month juvenile commitment was $70,827. The average length of stay for a delinquency commitment was 8.8 months ($51,940) and the average length of stay for a court evaluation commitment was 3.5 months ($20,658). Since 2005, the cost of commitment has increased yearly to $86,861 in 2012.1 However; the most current cost data published by the Department of Juvenile Justice reflects 2005 expenses. The cost analysis below reflects the 2005 cost information and average lengths of stay by commitment type. Therefore, the analysis below represents a conservative estimate of savings.

Analysis Methodology

The methodology for calculating the cost avoidance of Redeploy involved several steps:

  1. Compare the baseline eligible commitment number to the observed number of eligible commitments for a given year. The baseline is the average number of eligible commitments reported for a site during the years preceding the award of a Redeploy grant. There is one exception, St. Clair County, for two baselines reused. Because St. Clair County experienced a 150% increase in eligible commitments from 2001 to 2004, the Redeploy Illinois Oversight Board (RIOB allowed St. Clair County to use the single preceding year (2004) as its initial baseline (86 commitments). Beginning in the 3rd year of implementation, the RIOB adjusted the baseline to be the average number of eligible commitments for 2003-2005 (74 commitments). The difference between the baseline and eligible commitments for a given year are considered to be youth who have been diverted from commitment or Redeployed.
  2. Determine among Redeployed youth the number that would have been committed for evaluation and full commitment. According to IDJJ (2005), nine percent of new admissions are for a court evaluation. Therefore, the factors of .09 and .91 were applied to the number of Redeployed youth.
  3. The costs associated with commitment were then applied to the number of redeployed youth. The average length of stay for a delinquency commitment was 8.8 months ($51,940) and the average length of stay for a court evaluation commitment was 3.5 months ($20,658).

2005-2010 Redeploy Illinois Cost Analysis

Table 17 depicts the overall cost analysis and reduction percentages for each of the Redeploy sites since the program began in 2005. For St. Clair County and for Peoria County the data is reflected through June 30, 2011; for the remaining sites the data is reported through December 31, 2010.

Redeploy Illinois began as a pilot project in four sites and has since expanded to eight sites and 28 counties. The programs have provided individualized intensive services to more than 1,500 youth during this period. Prior to implementation in these counties, on average, 356 youth eligible for Redeploy services were being committed to DJJ each year. Because of Redeploy Illinois, these counties have instead committed 174 youth per year on average since 2005, a 51% reduction from the previous trend.

Table 17 further indicates that an estimated 1,737 youth would have been committed to IDJJ based on the previous trend data. Since implementation began, 85 Redeploy eligible youth were committed to IDJJ from these counties. This represents a 51% reduction or 886 fewer youth being committed to IDJJ, saving Illinois taxpayers an estimated $40 Million in unnecessary incarceration costs.
