The Crime Survey for England and Wales (CSEW) reported in 2013 that there were an average of 278,000 hate crimes a year with 40% being reported according to a victims survey, although police records only identified around 43,000 hate crimes a year. It was reported that police recorded a 57% increase in hate crime complaints in the four days following the UK's European Union membership referendum; however, a press release from the National Police Chief's Council stated that "this should not be read as a national increase in hate crime of 57 percent".
