People aged 65 and older are universally accepted as senior citizens. Some programs and retailers define senior-citizen status earlier than 65, including college programs that offer reduced tuition for seniors.
Beginning at age 55, older adults can begin to participate in senior-discount programs. Many retailers offer customers 55 and older the opportunity to shop during senior-discount days and provide a percentage off any purchases made. At age 60 or 62, depending on the program, older adults may receive reduced tuition rates at colleges and universities to take continuing-education courses and receive discounts from the federal government on admission to federal parks, as these entities typically recognize senior-citizen status prior to age 65.
