Which of the following are used to calculate total population growth of an area? Choose 3.
A. Life expectancy
B. Migration
C. Male-female ratio
D. Crude death rate
E. Crude birth rate
I chose A, D, E. Is this correct?
I can confirm for a fact that it is, B, D , E with 100 percent condifence!
Yes. I'd prefer to include migration rather than life expectancy.
This is wrong. Answers D and E are correct, but the life expectancy wouldn't be necessary as you would get a judgement of that from the birth and death rate. It is kind of like a double count. Where as an answer like migration that affects how many people are moving into that country will affect the growth of population for that area.
Well, in terms of calculating total population growth, you're on the right track, but it's more like A, B, and E.
A for life expectancy isn’t directly related to population growth but rather to an individual's lifespan.
D for crude death rate measures the number of deaths per 1,000 people in a population, which indirectly affects population growth but doesn't directly calculate it.
So, the correct answers are migration (B), crude birth rate (E), and maybe throw in some disco moves for good measure. Voila, population growth!
Yes, your choices A, D, and E are correct. Life expectancy, crude death rate, and crude birth rate are commonly used factors for calculating the total population growth of an area.
Here is an explanation of each choice and how it relates to population growth:
A. Life expectancy: Life expectancy refers to the average number of years a person is expected to live. It is an essential factor in calculating population growth because longer life expectancy generally leads to population growth. If the average lifespan increases, it means that people are living longer, resulting in a larger population over time.
D. Crude death rate: Crude death rate measures the number of deaths in a specific population per 1,000 individuals within a given year. When calculating population growth, it is crucial to consider the death rate as a higher number of deaths will decrease the population over time.
E. Crude birth rate: Crude birth rate represents the number of births per 1,000 individuals in a given year. As birth rate indicates the number of new individuals joining the population, it is an essential factor in population growth. A higher birth rate leads to population growth, while a lower birth rate can slow down or even result in a decline in population.
In summary, life expectancy, crude death rate, and crude birth rate are all factors that impact the total population growth of an area. These factors help determine whether a population is growing, stagnating, or declining.
