The Crime Survey of England and Wales (CSEW) said there were eight million crimes against households and adults in that period.
Addressing the the issue of data reliability the Minister for Policing, Criminal Justice and Victims, Damian Green, told BBC News steps needed to be taken to ensure police crime statistics were recorded as accurately as possible.
