^"The Language Of Ageism: Understanding How We Talk About Older People". Dictionary.com. 2021-05-19. Retrieved 2023-07-13. When is middle age? We define middle age as "the period of human life between medical youth and old age, sometimes considered as the years between 40 and 60 or thereabout."Given the different views on when old age begins, it shouldn't surprise you to learn that the exact range of middle age is not set in stone either. In general, our age range of "40-70" is around the age range generally used to say when middle age supposedly occurs. Polling shows that people may think middle age begins later or earlier depending on who you ask.
