The above two charts are the result of two studies conducted in 2009 to determine the percentage of incoming 911 calls made by cell phones. For more information about using cell phones to call 911, visit our Calling 911 page.

Information for the charts above were derived from 911 records and may differ from stats of the individual departments due to further investigation and possible reclassification of the calls after they have been handled. Also the statistics above do not include self-initiated calls such as traffic stops, flag downs, and walk-throughs. The numbers represent actual incoming calls to the 911 center for request for law enforcement, fire, or medical assistance.
