What is the primary age group targeted by Medicare's insurance program?

The correct answer focuses on individuals who are aged 65 and older because Medicare primarily serves this age group. This age threshold is significant as it was established by the Social Security Amendments of 1965, which created the Medicare program to address health care needs of older adults who are more likely to experience chronic health issues and require extensive medical care. By targeting those aged 65 and above, Medicare aims to provide essential healthcare coverage, including hospital insurance (Part A) and medical insurance (Part B), to enhance health security for older adults.

While there are various supplemental programs and services that may address the needs of those younger than 65, the foundational intent of Medicare centers specifically on the 65 and older demographic. This age group encompasses retirees who often experience a greater reliance on medical care due to aging-related health challenges, making Medicare a critical source of financial support for healthcare expenses.
