For decades, Baby Boomers were America’s demographic giant, influencing everything from suburban housing and the workplace to retirement planning and Social Security. Now that enormous generation is getting smaller, and in 2026 its oldest members are turning 80 while its youngest are 61 or 62, depending on their birthday. Roughly 66 million Baby Boomers remain in the United States based on the latest population data and estimates, a significant decline from the generation’s peak. That shrinking Baby Boomer population isn’t merely an interesting demographic statistic because it has implications for housing, inheritances, health care, retirement programs, and the labor force. Understanding what is happening starts with separating the number of babies originally born during the boom from the number of people from those birth years who live in America today.
