Census Report: U.S. Population Will Get Older, More Diverse

New U.S. Census Bureau projections anticipate the national population to become older and more diverse over the next 40 years, reports the Associated Press . A growing U.S. median age will be accompanied by a smaller ratio of employees in the workforce who can cover the payroll tax that funds Social Security payments, and Americans 65 and older will outnumber children for the first time in U.S. history in 15 years. "The youngest baby boomers are 55 and older now," said demographer Allison Plyer. "In 10 years, they will be 65 and older. And as those folks pass away over the decades, that's a very larger section of our population reaching an age where they will likely experience mortality." The Census Bureau also forecasts that no single race group will comprise more than half of U.S. children by 2020. Non-Hispanic whites are expected to fall below 50 percent of the population in four decades, from 199 million in 2020 to 179 million in 2060. Meanwhile, people who identify as biracial or multiracial will be the fastest-growing group in the next 40 years as births overtake deaths.
