"The United States is aging at an unprecedented pace. The number of Americans ages 65 and older has nearly doubled since 2000—reaching 61 million in 2024, or more than 1 in 6 Americans—and is projected to climb to 82 million by 2050. The oldest Americans, those ages 85 and older, are the fastest-growing age group and most likely to need extensive support and care.
"Living longer is a profound achievement. But longer lives do not automatically mean healthier, more secure, or more equal ones. Across two decades of research, a consistent picture has emerged: The experience of aging in the United States differs enormously—and those differences are not random. They are shaped by education, income, geography, racial disparities, and early-life experiences long before people reach older adulthood.
