The map delineates the spread of the city of Alexandria, while the line graph illustrates the expansion of the Egyptian population over a period of 140 years from 1840 to 1980.
Overall, it is clear from observation that not only did the city demonstrate the expansion, especially along the coast and Lake Marriot, but the population of inhabitants also experienced an upward trend, in millions, across the entire duration of the period.
In the map, the city was around 4 square kilometers in size in 1840, concentrating on the center of the map. In contrast, despite slightly expanding in 1900, the size of the city rapidly soared across the northwestern coast in 1960; furthermore, this size continued to significantly rise to surround Lake Mariout in the southeast, reaching a total of 100 square kilometers by 1980.
In the line chart, there was a modest increase in the initial 40 years from around 250 thousand people to just over 500 thousand people. Nevertheless, with the expansion of the city, this number dramatically rose to hit a high of 3.2 million in inhabitants towards the end of the period.
