Which demographic is primarily covered by Medicare?

Medicare primarily covers persons aged 65 and older. This demographic is specifically targeted because Medicare was designed to provide health insurance to older adults who often face higher medical costs due to age-related health issues. Beyond just age, Medicare also serves individuals under 65 who have certain disabilities or conditions such as end-stage renal disease or ALS (amyotrophic lateral sclerosis). However, the core and most recognized coverage group remains those who are 65 and older, reflecting the program's origins and primary focus on geriatric healthcare needs. By catering mainly to this age group, Medicare plays a crucial role in ensuring that seniors have access to necessary medical services and financial support during their retirement years.
