 "notes": [
  "Incidents of self-harm and of assault in prison custody in England and Wales, in each year to June, as establishments record them in HM Prison and Probation Service's incident reporting system; the MoJ marks the latest year provisional. Male and female establishments are the type of establishment, which the MoJ says may not be the prisoner's recorded sex.",
  "Self-harm figures from April 2019 and assault figures from April 2018 leave out incidents in the youth estate, which the MoJ could not split out before then, so the MoJ says the years that span those dates are not comparable with the years before or after.",
  "One person can self-harm more than once, so incidents are not people: the MoJ gives the number of people who self-harmed apart, and says self-harm in prisons cannot be counted with absolute accuracy. Assaults on staff and between prisoners are both counted in all assault incidents.",
  "If this subject affects you, Samaritans are there day or night, free on 116 123."
