Population change refers to the transformation that occurs in a population over time. The modifications that happen in a population are as a result of factors like births, deaths, migration, and others. Three patterns of population change are:a. (A) Young children have a lower death rate in Country 1 than in the other countries:

This pattern depicts a scenario whereby children are more likely to survive in Country 1 than the other countries. Such a pattern could occur due to improved healthcare facilities, which provide access to medical resources like vaccines, immunizations, and other health programs that help to maintain the health of young children. This pattern could also be a result of education, which emphasizes healthy living standards for the citizens of a country.

As a result, the population of young children in Country 1 is likely to increase. b. (B) Young children have a higher death rate in Country 1 than in the other countries: This pattern suggests a scenario whereby young children in Country 1 have a higher probability of dying than the other countries. This pattern could be a result of poor healthcare facilities, a lack of access to medical resources like vaccines, immunizations, and other health programs that help to maintain the health of young children.

As a result, the population of young children in Country 1 is likely to decrease. c. (C) More young children live in Country 3 than in the other countries: This pattern shows a scenario whereby Country 3 has more young children than the other countries. This pattern could be a result of the high birth rate in Country 3. Such a pattern could occur due to various factors like the cultural and religious beliefs of the people in Country 3.

As a result, the population of young children in Country 3 is likely to increase. d. (D) Fewer young children live in Country 2 than in the other countries: This pattern shows a scenario whereby Country 2 has fewer young children than the other countries. This pattern could be a result of the low birth rate in Country 2. Such a pattern could occur due to various factors like family planning, education, and other cultural beliefs. As a result, the population of young children in Country 2 is likely to decrease. The correct answer is A.
