Approximately how many older adults were there over 65?

• A. 10 million
• B. 35.6 million
• C. 60 million
• D. 100 million

Answer: (B)

Understanding how many people are over 65 helps with planning care, resources, and services for aging populations. The figure of about 35.6 million sits in a plausible range for the United States’ older adult population in the data often used in healthcare material. It reflects a sizable, but not yet the largest, aging group, which is the level of detail many care-planning contexts expect.

The other options are clearly off for typical course data: 10 million underestimates the scale of older adults needing various supports; 60 million would imply a much larger share of the population than is commonly cited in standard references; and 100 million is far beyond what a single country’s 65+ population would be in most contexts.
