The age for senior discounts varies depending on the retailer or establishment. Some senior discounts start as early as age 50, while others start at age 55, 60, or 65. The majority of senior discounts start at age 55 or 60. According to the U.S. Census Bureau, people who are aged 65 and older are considered part of the “older population” category for the purposes of data collection and reporting. However, some retailers may have their own policies for senior discounts, and not all businesses offer senior discounts. It is always best to ask about senior discounts before making a purchase, as not all businesses advertise their discounts for older adults.
