The Statistics tab is to help you identify how many reports were in the original query and how many you did not include if you unchecked any reports. In the center is the System type that is specific to your agency and/or state. NIBRS is the basic and will be used by all agencies that report by Summary UCR Reports and those agencies reporting directly to the NIBRS Unit at the FBI.
Note: While UCR functionality is still available within Online RMS, the FBI is no longer accepting UCR Summary Data as of Jan 1, 2021.
