How does a high birth rate impact a country's population?

A high birth rate has a significant impact on a country's population dynamics, primarily leading to a rapid increase in population size. When the birth rate is elevated, it means that a larger number of individuals are being born within a specified period, which contributes to overall population growth. This influx of new births can outpace other demographic factors such as mortality rates, especially in countries with lower death rates due to improvements in healthcare and living conditions.

As the population increases rapidly, several implications arise, including increased demand for resources, potential strain on infrastructure, and the need for adequate services such as education and healthcare to accommodate the growing number of inhabitants. This rapid growth can also shape economic development and social structures, often leading to challenges in employment and service provision.

The other options do not align with the reality observed in demographics. A stable population would typically require a balance between birth and death rates, not a high birth rate. Similarly, a decline in population would generally be associated with a low or negative birth rate, and stating that a high birth rate has no significant impact disregards the profound effects on population growth and societal needs.
