What percentage of the US population is aged 65 or older?

The selection of 13% as the percentage of the US population aged 65 or older is informed by demographic data collected from government sources such as the U.S. Census Bureau. This percentage reflects the significant growth in the older adult population due to factors such as increased life expectancy and the aging of the baby boomer generation. It is important to note that this demographic is expected to continue growing, leading to potential implications for healthcare, social services, and economic policies.

The other percentages do not accurately represent the current statistics on this age group. For instance, a lower percentage would underestimate the actual number of older adults, misrepresenting the aging trends.
