A research paper on "matures aux USA" (older adults in the USA) explores the significant demographic shift as the "baby boom" generation reaches retirement age, reshaping the country's social, economic, and healthcare landscapes. By 2030, an estimated 1 in 5 Americans will be 65 or older.

The aging of the U.S. population is unprecedented, with the "late elderly" (those 75 and older) growing rapidly.
