The image presents two visual data representations. The first graph illustrates world population growth from 1800 to 2100 in billions: 1 billion at 1800, 1 billion at 1850, 2 billion at 1900, 3 billion at 1950, 5 billion at 2000, a peak at 10 billion by 2050, and projected decline to 9 billion by 2100. The second graph is a bar chart showing world urban population in billions from 2005 to 2030 across developed and developing regions. In 2005, developed regions have approximately 1 billion, developing regions about 2 billion; in 2010, developed regions around 1.2 billion, developing regions roughly 2.5 billion; in 2015, developed regions about 1.4 billion, developing regions about 3 billion; in 2020, developed regions approximately 1.6 billion, developing regions around 3.5 billion; in 2025, developed regions about 1.8 billion, developing regions near 4 billion; in 2030, both regions collectively surpass the 6 billion mark, with developing regions significantly leading.

The given graph demonstrates the increase in population number worldwide in 300-year period, while the chart depicts the changes number of people living in cities between 2005 and 2030.
Generally, the upward trend is noticed throughout the given period with sudden decline by last eighty years. The number of population gradually increased from 900 million un to 2,7 billion until 1950 then sharply reaching the peak of 9 billion in 2025. However, after 2025 up to 2100 the sudden decrease is demonstrated.
The population of urban areas, specifically in developing regions experienced moderate growth throughout the 25-year period. The number of population grew for 500 million each 5-year period, reaching 4 billion in 2030. In contrast, the number of population in developed regions remained the same in 25 years, comprising 1,5 billion people.
