Worked Solution & Example Answer:Examine the population pyramids above - Junior Cycle Geography - Question A - 2014
Step 1
Describe the impact of birth rates and death rates on the structure of each of the Pyramids A and B.
Answer
The population pyramids illustrate the demographics of two different populations, showcasing distinct impacts related to birth rates and death rates.
-
Pyramid A indicates a high birth rate, as reflected by the wide base of the pyramid. This suggests a youthful population with a significant proportion of individuals in the lower age cohorts (0-14 years). High birth rates usually correlate with limited access to family planning, cultural factors favoring larger families, and lower female education levels.
-
The pyramid also demonstrates relatively high death rates, particularly among older age groups. The tapering at the top suggests that fewer individuals survive to old age. This could be due to poor healthcare access, high rates of disease, or inadequate nutrition in the population.
-
Conversely, Pyramid B shows a lower birth rate compared to Pyramid A. The base is narrower, indicating that fewer children are born. This could be attributed to increased access to education, healthcare, and family planning resources, which often accompany higher levels of socioeconomic development.
-
Pyramid B also displays lower death rates across all age groups, especially among older populations. The broader top of this pyramid indicates that more individuals live to advanced age, often associated with better healthcare systems, improved living conditions, and healthier lifestyles.
Step 2
Explain two reasons why life expectancy is higher in some countries.
Answer
-
Access to Healthcare: In many wealthier countries, citizens enjoy better access to comprehensive healthcare services, which significantly improves life expectancy. Early detection of diseases, preventive care, and advanced medical technologies contribute to individuals living longer, healthier lives.
-
Social and Economic Factors: Countries with higher life expectancy often have stronger social support systems and economic stability. High levels of education, access to nutritious food, and safe living conditions all foster environments where people can maintain good health and longevity.
