A. A low percentage of pre-reproductive individuals
- An "Urn" shaped pyramid refers to a population pyramid that has a narrow base and wider middle section, resembling the shape of an urn.
- In this type of pyramid, the percentage of pre-reproductive individuals (typically children and adolescents) is low compared to the total population.
- This means that the number of individuals in the younger age groups is smaller than those in the older age groups.
- This demographic pattern suggests a decreasing population growth rate because there are fewer individuals in the reproductive age group to produce offspring.
Reasoning:
- In an "Urn" shaped pyramid, the base represents the younger population, while the middle section represents the middle-aged population.
- Since the percentage of pre-reproductive individuals is low, it indicates a smaller number of individuals in the reproductive age group.
- This implies that there are fewer individuals capable of giving birth to the next generation, leading to a low birth rate and a decreased population growth rate.
- As a result, option A, which states "a low percentage of pre-reproductive individuals," is the correct answer.
Note: It is important to mention that population pyramids provide a visual representation of the age and sex distribution within a population. They help to analyze the demographic characteristics, such as birth rates, death rates, and population growth rates, of a particular region or country. The shape of a population pyramid can provide insights into the population's past and potential future growth trends.
