Which of the following describes demographic transition?
a period in which a society moves from high birth and death rates to low birth and death rates a period in which a society moves from high birth and death rates to low birth and death rates a graphical representation of the population by age and sex a graphical representation of the population by age and sex a statistical measure of the average number of years a person is expected to live a statistical measure of the average number of years a person is expected to live the total number of live births per 1,000 population at a given time
The first option, "a period in which a society moves from high birth and death rates to low birth and death rates," describes demographic transition.
Demographic transition refers to a period in which a society moves from high birth and death rates to low birth and death rates. It is the process of transitioning from a high population growth rate to a low population growth rate.
The correct answer is: a period in which a society moves from high birth and death rates to low birth and death rates.
Demographic transition refers to the process of a society transitioning from a high birth and death rate to a low birth and death rate. This transition typically occurs as a result of social, economic, and technological changes within a society.
To determine the correct answer from the options provided, we can use the elimination method. Let's analyze each option:
- Option 1: Describes demographic transition as a period in which a society moves from high birth and death rates to low birth and death rates. This aligns with the description of demographic transition and is a correct answer.
- Option 2: Mentions a graphical representation of the population by age and sex. While this is an important concept in demography, it does not specifically describe demographic transition. Therefore, this is not the correct answer.
- Option 3: Describes a statistical measure of the average number of years a person is expected to live. This concept is known as life expectancy and is not directly related to demographic transition. Therefore, this is not the correct answer.
- Option 4: States the total number of live births per 1,000 population at a given time. This concept is known as the birth rate, and while it is related to demographic transition, it does not capture the whole process. Therefore, this is not the correct answer.
Based on the explanations and elimination process, the correct answer is option 1: a period in which a society moves from high birth and death rates to low birth and death rates.
