Question

question 14

which of these represents the oldest population?

• centenarians
• the young old
• the oldest old
• the old old

Explanation:

Define the age subgroups in late adulthood

In developmental psychology and gerontology, researchers categorize the older population into distinct subgroups to better understand their unique needs and characteristics:

• The young-old: Generally refers to individuals aged 65 to 74.
• The old-old: Generally refers to individuals aged 75 to 84.
• The oldest-old: Generally refers to individuals aged 85 and older.

Analyze the term "Centenarians"

A centenarian is a person who has reached the age of 100 years or more.

Compare the age ranges to find the oldest population

Comparing the age thresholds of each group:

• The young-old: \(65 - 74\) years
• The old-old: \(75 - 84\) years
• The oldest-old: \(85+\) years
• Centenarians: \(100+\) years

Since centenarians must be at least 100 years old, this group represents individuals of a significantly higher age than the entry thresholds for the young-old, old-old, and oldest-old categories. Therefore, centenarians represent the oldest population among the choices.

Answer:

• Centenarians (Correct answer)
• The young old
• The oldest old
• The old old
