The Express tool provides a series of data perspective options based on the content area you are exploring.
For instance, Criminal Enforcement allows you to look at Agencies, Programs, and Lead Charge; Civil Enforcement provides Agencies and Causes; the other layers provide more geographical perspectives, such as State, District, or County (see image below showing different express menus).
note: When examining criminal and civil data, you may notice that the referrals, prosecutions, convictions, and/or declinations for a given year do not appear to "add up". This is because referrals received in one year do not necessarily get prosecuted, convicted, or declined in the same year. It is common for cases to span two or more years.
