This is evident both intheir research priorities and in their technical support to nations of theirregion. Given the wide variatlon in the current and projecCed degree of the aglngof population in the rrorldrs major regions, the support of regional bodies is ofcrucial importance in helping nations respond to the policy implications of agingtrends in their particular dermgraphic and developmental contexts. 23.

**Analysis**
The text appears to focus on the demographic changes and their implications on policy-making, particularly in the context of aging populations. It discusses the importance of information exchange, research, and analysis in understanding the economic and social impacts of aging trends. The text also highlights the role of regional bodies, such as the United Nations regional commissions, in providing support to nations in responding to these trends. Given the emphasis on demographic changes and their implications on policy-making, I hypothesize that the text is more likely to fall under the categories related to social and economic development.
