Step 1
Analyze the year 2000 data
Answer
In the year 2000, the population distribution indicates a higher number of individuals in the middle age groups, specifically those aged 30-49. The bars for ages 20-29 and 50-59 show moderate numbers, while the younger age group (0-14) displays a noticeable decline, suggesting fewer individuals in those age ranges.
Step 2
Analyze the year 2020 data
Answer
Moving to the year 2020, the population distribution demonstrates a significant increase in the older age groups, particularly those aged 50-59 and 60-69. This shift indicates an aging population. Additionally, there is a slight reduction in the younger age groups (0-14), confirming the trend observed in the year 2000.
Step 3
Compare the two distributions
Answer
Comparatively, the charts reveal a clear aging trend in the population over the two decades. The increases in older age demographics strongly suggest improved life expectancy, while the decline in younger cohorts may reflect lower birth rates or migration trends. The overall shape of the population pyramid appears to narrow at the base and widen at the top, characteristic of an aging society.
