Convergence clubs, in global economic theory, pertain to levels of international attainment.
Groups of countries are classified based on educational levels, income per capita and other measurable factors.
Rich, developed nations such as the United States and those of Western Europe are grouped into a higher-income per-capita convergence level.
These groups help to identify similarities and differences between countries, and assist researchers in making generalized hypotheses.
