The first graph illustrates world population growth over three centuries since 1800, while the second graph gives predicted about urban populations figures for next 25 years.
At the beginning of the period number of world population stood at one thousand millions of people. Between 1800 and 1950 we saw steady growth in population from 1 billion to around 2.5 billion people. After that population increased again, but more steeply and currently the figure is approximately 6.4 billion people.
Projection shows a continued increase, during next twenty-five years and the global population is expected to peak at 8.2 billion by 2050, then return to around 6.4 billion by 2100.
Second graph outlines predicted urban populations in two other regions (developed and developing).
Overall almost all growth in population for next 25 years will be occur in developing regions. On other hand in developed regions amount of urban population will be constant, so is expected remain unchanged at about 1.3 billion over next two decades.
To sum up this two graph depicts upward trend in global population on ours Earth
until 2050/between 1800 and near future that is 2050.. After 2050 is expected significant decrease to 6.4 billion people by end of 21th century and even that developing countries will be play a key role in change world population growth.
