Operation Yewtree teams have spoken to 589 people in relation to offences carried out by the late broadcaster and others.
The alleged victims are 82% female and 80% children or young people, reports BBC News.
Operation Yewtree is investigating Savile's abuse under three sections - abuse committed by Savile alone; abuse committed by Savile along with others; and others committing abuse.
Gary Glitter, Freddie Starr, Dave Lee Travis and ex-TV producer Wilfred De'Ath are believed to be among other individuals arrested as part of the investigations.
Max Clifford was arrested by police last week for offences that do not directly link with Savile, while two more unidentified men have also been questioned.
The investigation was launched 10 weeks ago, with 30 officers involved at the cost of £2 million so far.
Police have recorded 199 alleged incidents in 17 police force areas, with 31 allegations of rape against Savile.
Met Police Commander Peter Spindler said: "Savile's offending peaked in the '70s and what we can show, or will be showing in the New Year, is how he used his position in society across the country - the crimes relate to 17 different police force areas - how he exploited this position to get his sexual gratification."
The BBC has also announced two inquiries in relation to the abuse claims along with an investigation into the dropping of a Newsnight special on Savile's alleged crimes.
