What is the fastest growing age section of the population?

Explanation:
The oldest age group is growing the fastest. As life expectancy rises and more people survive into very old age, the number of individuals living to 85 and older increases rapidly. Even though this group starts from a smaller base, its growth rate outpaces other age brackets because people are living longer and reaching advanced ages more frequently. In contrast, birth rates have fallen in many places, so younger groups like 0–4 and 18–24 aren’t expanding as quickly, and while the 65–74 group is increasing with aging cohorts, it doesn’t rise as fast as the 85+ group.
