Globalization refers to the integration of economies around the world through reduced barriers to trade and financial flows. It is driven by technological advances as well as economic, social, and political factors. Globalization can be measured across economic, social, and political dimensions. The most globalized countries according to research groups are Western European nations like Austria and the UK, while the least globalized are countries in Africa and Asia such as Haiti, Myanmar, and Burundi. Globalization has increased international trade dramatically and led to a more interconnected global financial system, with both benefits and challenges for national economies.
