Editing Filicide (section)

==Statistics==
A 1999 U.S. Department of Justice study concluded that mothers were responsible for a higher share of children killed [[infanticide|during infancy]] between 1976 and 1997 in the United States, while fathers were more likely to have been responsible for the murders of children aged eight or older.<ref>{{cite web |url=http://bjs.ojp.usdoj.gov/content/pub/pdf/wo.pdf |title=Women Offenders |access-date= 2018-05-29 |author1=Greenfeld, Lawrence A. |author2=Snell, Tracy L. |date=2000-03-10 |work=NCJ 175688 |publisher=U.S. Department of Justice, Bureau of Justice Statistics|archive-url= https://web.archive.org/web/20100603113816/http://bjs.ojp.usdoj.gov/content/pub/pdf/wo.pdf |archive-date= 2010-06-03 }}</ref> Parents were responsible for 61% of child murders under the age of five.<ref>{{cite journal | last1 = Friedman | first1 = S.

An in-depth [[longitudinal study]] of 297 cases convicted of filicide and 45 of filicide-suicide in the [[United Kingdom]] between 1997 and 2006 showed that 37% of the perpetrators had a recorded mental illness at the time. The most common diagnoses were [[mood disorder]]s and [[personality disorder]]s rather than [[psychosis]], but the latter accounted for 15% of cases. However – similar to findings in a large Danish study – the majority had not had contact with mental health services prior to the murders, and few had received treatment. Female perpetrators were more likely to have given birth as teenagers. Fathers were more likely to have been convicted of violent offences and have a history of substance misuse, and were more likely to kill multiple victims. Infants were more likely to be victims than older children, and a link to [[post-partum depression]] was suggested.<ref>{{cite web |url =https://www.manchester.ac.uk/discover/news/findings-from-most-in-depth-study-into-uk-parents-who-kill-their-children/ |title =Findings from most in-depth study into UK parents who kill their children |date =5 April 2013 |website =University of Manchester |access-date =26 February 2020 |archive-date =16 May 2020 |archive-url =https://web.archive.org/web/20200516212915/https://www.manchester.ac.uk/discover/news/findings-from-most-in-depth-study-into-uk-parents-who-kill-their-children/ |url-status =live }}</ref>
