Individualism, collectivism, and power distance can be linked together in different ways. They are typically studied together because overall in scoring, a country's PDI score is positively correlated with its degree of collectivism. This is explained as individualistic countries being typically focused on an individual and their desires, where power status has a less significant role, and collectivist countries focusing on the collective good. Hofstede found that individualism, collectivism, and power distance are greatly correlated to a nation's wealth. Wealthy countries usually score high for individualism and low on the Power Distance Index, while poorer countries score high for both collectivism and the PDI.
