Examine the table above showing the number of people living in urban areas and the percentage of the total population living in urban areas in selected regions - Leaving Cert Geography - Question 12A - 2018

To calculate the percentage change in the number of people living in urban areas in Ireland from 2014 to 2050:

1. The number living in urban areas in 2014 is 2,944,000.

2. The number living in urban areas in 2050 is 4,474,000.

3. The formula for percentage change is:

   ext{Percentage Change} = rac{ ext{New Value} - ext{Old Value}}{ ext{Old Value}} imes 100

4. Substituting the values:

   ext{Percentage Change} = rac{4,474 - 2,944}{2,944} imes 100 \\ ext{Percentage Change} = rac{1,530}{2,944} imes 100 \\ ext{Percentage Change} \\ ext{≈ 51.97%}

One reason for the increase in the number of people living in urban areas in Ireland is the trend of urbanization, where more people migrate from rural areas to cities seeking better employment opportunities, modern amenities, and improved quality of life.

Two potential problems resulting from the significant increase of people living in urban areas in Sub-Saharan Africa by 2050 include:

1. Overcrowding: The influx of people can lead to overcrowded cities, putting pressure on housing, transportation, and public services, which may result in slums and inadequate living conditions.

2. Strain on Resources: Rapid urbanization can deplete resources such as water, sanitation, and healthcare facilities, leading to shortages and increased competition for these essential services.
