The given table illustrates the data of world population in billions along with region wise proportion in the year 1950, 2000 and their future estimation in the year 2050.
Overall, it is evident that the world population will grow in numbers and Africa will experience the highest growth in population while Europe and North America will be the only region with decreasing rate of population growth. The other regions remain nearly stable throughout the period.
The world population experience constant growth from 2.5 billion in the year 1950 to an estimated 9 billion in the year 2050. Africa had 9% of the total world population in the year 1950, which will nearly double to 20% in 2050, the only region with a positive growth rate. On the other side, Europe and North America are the only region with a negative population growth rate, starting at 22% & 7% in the year 1950 and will end with 7% and 4% in the year 2050, respectively.
The remaining regions, i.e. Asia, Latin America, and Oceania show a similar pattern of variation in the percentage of population growth for the given time period, starting at the lowest value in the year 1950, increased to the maximum value in 2000, estimated to remain constant till the year 2050.
