Both given graphs depict transformations in the trends of the urban and rural population, as well as the diversity of age groups between 1950 and 2040.
Overall, from 1950 to 2000, according to the population line graph, the number of residents in urban areas increased substantially in total, except for the steady growth in the rural one. In addition, the 16-65 age group escalated dramatically;otherwise, the rest have stayed low for the past 50 years. These trends are predicted to continue until 2040.
The number of individuals residing in rural areas has seen only slight changes and is projected to follow the same pattern from 1950 to 2040. In stark contrast, the urban population has experienced significant fluctuations and is expected to maintain this trend leading up to 2040. The overall proportions closely mirror those of the urban areas.
In terms of age group changes, there have been minor fluctuations in both the under 15 and over 65 age segments, with both groups remaining relatively constant at around 5 million. Conversely, the age group of 15 to 65 has experienced—and is expected to continue to see—substantial growth, with numbers projected to rise to 35 million, up from nearly 6 million in 1950.
