Worked Solution & Example Answer:Analyse the data shown in Figure 7a and Figure 7b - AQA - A-Level Geography - Question 4 - 2020 - Paper 2
Step 1
Percentage of deaths attributed to air pollution decreases with income level
Answer
The data in Figure 7a indicates that the percentage of deaths attributed to air pollution decreases as the income level of countries increases. Low-income countries have the highest percentage of deaths attributed to air pollution at approximately 10.6%, while high-income countries demonstrate significantly lower numbers, nearing 1%.
Step 2
Connection with PM₂.₅ pollution levels
Answer
Figure 7b shows the global distribution of PM₂.₅ concentrations. It supports the observation from Figure 7a that low-income countries are experiencing higher levels of PM₂.₅, which aligns with the higher death rates from air pollution. In contrast, higher income regions such as Europe and parts of North America report significantly lower PM₂.₅ levels.
Step 3
Regional variations in air pollution
Answer
There are distinct regional variations in PM₂.₅ concentrations as shown in Figure 7b. For instance, while South America shows high fluctuations in PM₂.₅, other areas like Europe and North America maintain consistently lower levels. This variability correlates with the data in Figure 7a indicating that regions with the highest PM₂.₅ levels often align with those experiencing the most deaths from air pollution.
Step 4
Overall conclusion on public health
Answer
Low-income countries not only have the highest death rates attributed to air pollution but also correspondingly higher PM₂.₅ pollution levels. Conversely, high-income countries exhibit lower pollution levels and therefore fewer deaths. This emphasizes the link between economic status and public health regarding air quality.
