Sample Writing Task 1 Answer

Below is a sample response for the chosen prompt:

The line graph illustrates the changes in urban population density in Asia, Europe, and North America from 2000 to 2023.

Overall, it is evident that the urban population density has been consistently increasing in all three continents over the given period. Asia has the highest urban population density, followed by North America and Europe.

In 2000, Asia’s urban population density started at 800 people per square kilometer, significantly higher than North America’s 600 and Europe’s 400. By 2005, Asia saw a considerable rise to 900, while North America and Europe increased slightly to 650 and 450, respectively.

Moving to 2010, the upward trend continued, with Asia reaching 1000, North America 700, and Europe 500. The following five years experienced similar growth patterns, with all continents seeing a steady increase of approximately 100 people per square kilometer per five years.

The period between 2015 and 2020 marked a more pronounced growth, especially for Asia, which surged to 1200 by 2020. North America and Europe also showed significant increments, reaching 800 and 600, respectively.

By 2023, Asia’s urban population density peaked at 1300, maintaining its position as the continent with the densest urban populations. North America and Europe finished the period with densities of 850 and 650, respectively.

In summary, all three continents displayed a notable increase in urban population density between 2000 and 2023, with Asia leading the trajectory throughout the period.
