Main points
There were 571 homicides (murder, manslaughter and infanticide) in the year ending March 2016 in England and Wales. This represents an increase of 57 offences (11%) from the 514 recorded in the previous year.
The number of homicides has shown a general downward trend over recent years and the 571 recorded was still one of the lowest levels since the late 1980s, despite having increased from the previous year.
There were 9.9 offences of homicide per million population, and the homicide rate for males (13.8 per million population) was more than twice that for females (6.0 per million population).
Women were far more likely than men to be killed by partners or ex-partners (44% of female victims compared with 7% of male victims), and men were more likely than women to be killed by friends or acquaintances (35% of male victims compared with 13% of female victims).
There were 38 homicide victims aged under 16 years in the year ending March 2016, the lowest number since data on homicide victims by age of victim was first published in 1972.
The most common method of killing continued to be by knife or other sharp instrument with 213 victims killed in this way, accounting for over 1 in 3 (37%) homicides.
The 26 homicide victims (5% of the total) that were killed by shooting showed an increase of 5 from the previous year, but is otherwise the lowest number since 1980 (19 homicides).
