Note: The relatively constant predominance of suicide rates in males over suicide rates in females: 3.2:1 in 1950, 3.6:1 in 1995 and 3.9:1 in 2020. There is only one exception (China), where suicide rates in females are consistently higher than suicide rates in males, particularly in rural areas (Phillips and Zhang, 2002).
