Most of the quantitative data in this report was provided by the Department, although the evaluation team also had access to annual and other reports from each RCS or UDRH. The data presented in charts and tables in this report, unless otherwise identified, has been derived using Department consolidated UDRH data provided to Urbis throughout the evaluation, including a final update on 16th September 2008. Consolidated data presented in chapter 4 was compiled by the Department from UDRH six-monthly reports. All reasonable steps were taken to ensure relevant data has been included. However, a full audit of data was not within the scope of this evaluation, and minor discrepancies may exist between the six-monthly reports of the UDRHs and the data cited in chapter 4.
