Jawaban:

1. Crude birth rates of more than 30 per 1,000 are considered high, and rates of less than 18 per 1,000 are considered low. ... Many African countries have a very high crude birth rate, and women in those countries have a high total fertility rate, meaning they give births to many children in their lifetime.

2. The crude death rate measures the rate of deaths for every 1,000 people in a given population. Crude death rates of below 10 are considered low, while crude death rates above 20 per 1,000 are considered high.

3. The rate of population growth is the rate of natural increase combined with the effects of migration. Thus a high rate of natural increase can be offset by a large net out-migration, and a low rate of natural increase can be countered by a high level of net in-migration.

4.Age composition refers to the number of people in different age groups in a country. It is the most basic characteristic of a population. (ii) To an important degree, a person's age influences what he needs, buys, does and his capacity to perform.

5.population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population. ... A population pyramid can be used to compare differences between male and female populations of an area

6. A population pyramid that is very triangular (eg Mozambique in 2000) shows a population with a high number of young dependants and a low life expectancy.

A population pyramid that has fairly straight sides (more like a barrel) shows a population with a falling birth rate and a rising life expectancy.

Over time, as a country develops, the shape changes from triangular to barrel-like.

Places with an ageing population and a very low birth rate would have a structure that looks like an upside-down pyramid.

7. Two primary reasons for this are increased life expectancy and lower birth rates. Currently, the majority of the countries facing this demographic phenomenon consists of advanced economies, such as Japan and many parts of Europe.
