Homicide in the US, war in Africa, rape, spousal abuse, child abuse, spanking and hate crimes have all declined since records were first kept.

The claim has seven parts: US homicide, war in Africa, rape, spousal abuse, child abuse, spanking and hate crimes. Each must have declined overall from the start of systematic records to about 2011, judged on long-run trend, not year to year. True: the available data series (e.g. FBI UCR/NCVS, CDC, UCDP/PRIO for African conflict, NIS/NCANDS for child abuse, surveys of attitudes to and use of spanking, FBI hate crime statistics) show a net decline for all seven up to about 2011. Mostly true: all show net long-run declines, but one has a minor caveat (e.g. a series that began only recently, or a temporary rise). Mixed: roughly half of the categories show a net decline since records began and the rest do not. Mostly false: most categories do not show a decline since records began, or declines appear only over selected recent windows while the full record does not show them. False: the data show that most or all of the categories rose or stayed flat since records began.

I rated this claim mixed: the evidence backs some of the seven declines but contests or leaves out others. For rape, NCVS data show a decline across the whole survey since 1973 (E2). Intimate partner violence fell 64% from 1994 to 2010 (E4), spanking fell over 1988–2011 (E9), and African armed conflict fell in the 2000s compared with the 1990s (E11), but each of these covers only part of the record. US homicide fell only to levels last seen in the mid-1960s (E5), which does not show a decline since records began. Physical child abuse is contested: hospital data and other sources do not match the agency data that show a fall (E3, E7), though sexual abuse fell from 1992 (E6). No evidence covers hate crimes before 2011 (E12 covers only 2010–2019).
