In the context of population change, if the birth rate is ____ than death rate, the population will ____.
Show answer & explanation
Correct answer: B
Explanation
Correct Answer:
Option 2 (Less, decrease)
Explanation:
Population change depends primarily on three factors: birth rate, death rate, and migration. If the birth rate is lower than the death rate over a given period of time, it simply means that the number of people dying is higher than the number of people being born. In such a situation, the total population of that area will decrease.
Additional Facts:
Population Growth: When the birth rate exceeds the death rate, the population increases.
Stable Population: If both the birth rate and death rate are equal, the population remains stable.
Natural Growth Rate: The difference between the birth rate and death rate is called the 'natural growth rate' of the population.
Migration: In addition to births and deaths, the movement of people from one place to another is also a major cause of population change.
