Of those, 400 are currently in prison.
A force spokesman said it is the police's duty to protect communities - and they do so by working with other agencies to manage the risks posed by violent and sexual offenders who have the "potential to cause the most serious harm".
The constabulary has issued the following information.
REGISTERED SEX OFFENDERS.
There are 2380 Registered Sex Offenders in the Avon and Somerset force area, which include 400 currently in prison.
The majority of them live in our communities.
With proper treatment and supervision, many can live productive and stable lives.
Their behaviour is monitored and if they are believed to be at risk for reoffending or do not comply with their licence conditions, they may be returned to prison.
