Overview
The prevalence of menopause is estimated to be about 50 million cases annually. Menopause naturally occurs in women between 49 to 52 of age the average. The fatality cases were 345 cases per 3191 women aged between 50-86 years in the United States. There is no racial predilection to Menopause, but African American women had experienced the largest number of menopausal symptoms compared with other ethnic groups.

Mortality rate
- In 1997, the fatality cases were 345 cases per 3191 women aged between 50-86 years in the United States over a mean follow-up time of 4.0 years.
- The mortality rate ratio (MRR) was 1.50% for women with menopause at age < 40, and the MRR of women with menopause at age 40-44 was 1.04%. While the MRR for women with menopause at age 45-49 was 0.96%.[5]
Race
- The prevalence of menopause does not vary by race.
