Thank you for your enquiry regarding homicide statistics.
Our most recent publication on homicides entitled Homicide in England and Wales, year ending March 2017, might be useful to you. Figure 3 presents the number of homicide offences currently recorded by the police, by age of victim, from March 2007 to March 2017.
The appendix tables published alongside the article, also contain tables with age breakdowns, specifically table 3.
Age is broken down as following: 'Under 16', '16 to 24', '25-34', '35 to 44', '45 to 54', '55 to 64', '65+'.
The data presented uses police recorded data which is held by the Home Office. If you require further assistance regarding age breakdowns, you may wish to contact them directly via: CrimeandPoliceStats@homeoffice.gov.uk
