The graphs below provide information on global population figures and figures for urban populations in different world regions. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The graph reveals the number of the world population and the distribution of people in cities in different parts across the globe.
Overall, the population size has been increasing. Though the increment was gradual at the beginning, it was lifted strikingly. Moreover, the number of people living in cities remained constant in developed nations, increasing in developing countries throughout the stated period. Another interesting finding is that urban residents in less developed countries are much more than people living in the cities of high-income countries.
Looking at the details, initially, the growth of the world population was slow; it took more than one century to double the number of people of the world, which was in 1920. Starting from the early 20 century, population growth has been increasing sharply. As a result, over 100 years, the population number increased by more than three-fold. In addition, the trend shows that the growth will continue for the coming three decades. After that, the growth probably will stop, and the trend will be in the opposite direction.
When we compare the number of populations who live in the cities of developed and developing nations, the former the figure has been constant for the past nearly two decades, just above 100o in a million in and it will remain the same in the future. On the other hand, there has been a remarkable increase in developing countries. In 2015 just above 2 billion people were living in the cities; this number is expected to rise by about 200% and will be 8 billion after two decades in 2040.
To sum up, population growth has been increasing at an alarming rate since mid-1950 and will remain the same for the next 40 years. The other point is that cities are expanding in developing countries whereas developed nations have not shown significant changes.
