The report states that 3.7 million offenses were recorded in 2012, representing an 8 percent drop in crime from 2011, the office said in a release.
ONS researchers said there were drops in all the main crime categories, including violent and sex crimes.
Assaults were down 6 percent in 2012 from 2011, the report said, and robberies fell 13 percent. Sexual offenses fell 3 percent.
The ONS did find that instances of pickpocketing and bag snatches grew 8 percent. Researchers said this may be due to young people being targeted for cellphones.
"Anecdotal evidence suggests this is being driven by increases in mobile phone thefts, especially against younger victims," the report said. "A widely reported increase in the number of thefts from the person committed in London by criminals on bicycles and mopeds may also be a contributory factor."
