Question

In the country of Kong, if the birth rate is 22 and the death rate is 9, what is the annual rate of natural population change? Is this high or low? Explain. In how many years will the population double if the growth rate stays constant, and migration is not a factor? Is that high, low, or medium? Explain. The total fertility rate of Kong is 2.5. Is that high, low, or medium? Explain. Suppose you knew the age structure of the country, especially the percentage of people under the age of 15. Of what use is that information?

a) The annual rate of natural population change is 13, which is considered high.

b) The population will double in approximately 26 years, indicating medium growth.

c) A total fertility rate of 2.5 is considered medium, indicating replacement-level fertility.

d) Information about the age structure helps assess demographic trends and potential future population changes.

Answer 1

The annual rate of natural population change is 26, which is considered high. The population will double in approximately 26 years, indicating medium growth. A total fertility rate of 2.5 is considered medium, indicating replacement-level fertility. Information about the age structure helps assess demographic trends and potential future population changes.

Step-by-step explanation:

The annual rate of natural population change is 26, which is considered high.

The annual rate of natural population change is calculated by subtracting the death rate from the birth rate. In this case, it would be 22 - 9 = 13. This rate indicates that the population is growing at a relatively fast pace.

The population will double in approximately 26 years, indicating medium growth.

The doubling time can be calculated using the rule of 70, which states that the doubling time is approximately equal to 70 divided by the growth rate. In this case, the growth rate is 13, so the doubling time would be 70 / 13 = 5.38, which rounds up to 6. Thus, the population will double in approximately 26 years (6 x 26 = 156 years). This indicates medium growth.

A total fertility rate of 2.5 is considered medium, indicating replacement-level fertility.

The total fertility rate (TFR) measures the average number of children per woman. A TFR of 2.5 indicates that each woman, on average, is having 2.5 children. Replacement-level fertility, which is the level needed for a population to replace itself, is typically considered to be around 2.1. Therefore, a TFR of 2.5 is considered medium, indicating a somewhat higher fertility rate.

Information about the age structure helps assess demographic trends and potential future population changes.

The age structure of a country's population refers to the distribution of people in different age groups. This information is important because it can provide insights into demographic trends, such as population growth or decline, and potential future population changes. For example, if a large percentage of the population is under the age of 15, it may indicate a high birth rate and potential for future population growth. Age structure can also help policymakers plan for things like healthcare, education, and social services.
