The federal government established the Combined DNA Index System (CODIS) to share DNA matches among federal, state and local jurisdictions. The federal DNA Analysis Backlog Elimination Act of 2000 and Debbie Smith Act authorizations in 2004 and 2008 provide additional funding to state and local jurisdictions to help clear their rape kit testing backlogs. As of 2014, the federal government estimates a nationwide backlog of 400,000 rape kits, including many from the 1990s when evidence was collected but not tested for DNA due to high costs and more primitive techniques available at the time.
