Suicide mortality in Greater London: changes during the past 25 years

Suicide mortality in the area now administered by the Greater London Council was assessed for three five-year periods 1949-1953, 1959-63, and 1969-73. For each of the periods the standard mortality ratio (SMR) for suicide in various boroughs was calculated for men and women separately. The boroughs with high SMRs for men were constant. There was a pronounced change in the geographical distribution of high mortality among women. These findings support the hypothesis that the determinants of suicide differ between the sexes.
