Final answer:
Individuals are eligible for Medicare Part A benefits starting at age 65. Established in 1965, Medicare provides health insurance to the elderly, a group that has seen relative growth in the United States. The correct option is (4).
Step-by-step explanation:
Eligibility for Medicare Part A Benefits:
Individuals become eligible for Medicare Part A benefits at the age of 65. This age of eligibility aligns with historical definitions of 'elderly' and the qualifying age for federal benefits such as Social Security. Medicare, established in 1965, addresses health coverage for aging citizens, reflecting society's recognition of healthcare needs for older populations. With an aging demographic, the significance of Medicare has grown, with approximately 40 million eligible individuals in the early 2000s. The program's impact is evident in the political arena, where seniors demonstrate substantial influence by participating actively in elections and contributing to political campaigns.
As the population ages, the ratio of elderly citizens in the U.S. has increased over time, from one in thirteen in 1946 to an estimated one in five by 2030. This shift underscores the growing importance of Medicare and Social Security. The financial sustainability of these programs, funded by payroll taxes, has become a conversation of critical importance due to the expected rise in costs associated with a larger elderly population.
Although the eligibility for Medicare is set at 65 years old, there are discussions and debates around defining 'elderly'. The U.S. government and the World Health Organization (WHO) have different approaches to this classification, with the latter suggesting variations depending on the nation in question. Organizations like AARP, which provides benefits to older Americans, offer membership starting at age 50, reflecting the diverse perceptions of what it means to be elderly and the economic implications of aging.
