Examine the population pyramid above for Cork City and answer the following questions: (i) What percentage of females is in the 10 - 14 year age group? (ii) Which age group is the largest? (iii) Which is greater the percentage of males or females in the 80 - 84 age group? (iv) Calculate the percentage of children, both males and females in the 0 - 4 age group - Leaving Cert Geography - Question A - 2010

The largest age group can be identified by observing the widest section of the pyramid. In this case, the 20 - 24 age group shows the largest percentage at approximately 20% of the total population.

From the population pyramid, we see that in the 80 - 84 age group, females account for 6% while males account for 4.74%. Therefore, the percentage of females is greater.

For the 0 - 4 age group, the percentages are 7.22% for males and 7.55% for females. To find the total percentage of children in this age group, we add these values:

$7.22 + 7.55 = 14.77\%$ Thus, the total percentage of children (both males and females) in the 0 - 4 age group is 14.77%.

One significant difference is the shape of the population pyramid. The pyramid for Cork City is more rectangular, indicating a relatively stable population with lower birth rates and higher life expectancies. In contrast, a developing world city typically has a broader base, suggesting higher birth rates, and a more pronounced tapering at the top, reflecting lower life expectancies and higher mortality rates among the elderly.
