Explanation:

1. A population pyramid shows age - sex distribution. By comparing pyramids over time, trends in birth rates, death rates, and migration can be seen. For example, a widening base may indicate high birth rates, while a shrinking base can signal low birth rates.
2. Rwanda's population may continue to grow in the short - to medium - term due to high fertility rates. However, as development occurs, factors like increased access to education (especially for women) and family planning may lead to a slowdown in growth.
3. Japan's population is likely to decline in the future. This is due to a low birth rate and an aging population. With fewer young people having children and a large elderly cohort, the overall population size will decrease.
4. Industrialization impacts population in multiple ways. It can lead to urbanization as people move to cities for jobs. It also affects birth and death rates. Initially, death rates may decline due to improved healthcare, and later, birth rates may decline as people shift to smaller family sizes due to changing economic and social conditions.
