analysis: The text appears to be discussing demographic changes and population projections, with a focus on the working-age population and urbanization rates. The data provided seems to be related to the distribution of population across different regions and the percentage of urban population. This suggests that the text is more concerned with macroeconomic and social trends rather than specific industries or sectors.
