This line chart shows the information about world population development in developing countries and industrialized countries, from 1750 to 2050. To begin with, we can see that the population in developing countries increased dramatically from 1 billion in 1750 to 8 million in 2050. According to the graph, it only took developing countries 50 years to double the population from 2 billion to 4 billion. Last but not the least, the population development in industrialized countries, however, increased at a much lower rate. In conclusion, the population in developing countries is larger than that in industrialized countries throughout the period.
