Question

Quizplus · Accepted Answer

Japan and some countries in Europe, such as Germany and Italy, have already reached or are close to reaching a stable population where the birth rate is low and the population is aging. Without accepting immigrants, their population would continue to decline and the workforce would shrink, leading to economic issues. Other countries like Mexico and Brazil are still in the earlier stages of the demographic transition model and have higher birth rates, so they would not be considered postindustrial yet. European countries as a whole do not necessarily have the same demographic characteristics and some, like the UK, are still experiencing population growth through immigration. China and India are both still in the later stages of demographic transition, with high birth rates and growing populations.
