Question

The population pyramids of Japan for the years 1950, 2007 and on the basis of the estimated value for 2050 have been shown below to answer the questions that follow:

1. Comment upon the growth status of the population on the basis of the shape of the age pyramids.
2. What insights can you gain about their population dynamics?

Answer 1

1. 1950 – Expanding population: The 1950 pyramid has a broad base, showing a large proportion of young individuals. This indicates high birth rates and an expanding population, characteristic of rapid population growth.
2. 2007 – Stable population: The 2007 pyramid shows a more uniform distribution across pre-reproductive and reproductive age groups. This suggests lower birth rates and lower death rates, indicating a stable or stationary population with slow growth.
3. 2050 – Declining population: The projected 2050 pyramid is urn-shaped, with a narrow base and a larger elderly population. This reflects very low birth rates and increasing life expectancy, leading to a declining population.
