Along with race and gender, people commonly use age to categorize—and form stereotypes about—others. Of the three categories, age is the only one in which the members of the in-group (the young) will eventually join the out-group (the old). Although ageism is found cross-culturally, it is especially prevalent in the United States, where most people regard growing older with depression, fear, and anxiety. Older people in the United States are stigmatized and marginalized, with often devastating consequences.
