**Analysis**
The text appears to be discussing demographic data related to the age structure of different regions, specifically the dependency ratio, which is a common indicator used in economic development studies. The data is presented for different regions and time periods, suggesting that it may be used to analyze the impact of demographic changes on economic development.
