Final answer:
Gross Domestic Product (GDP) and Genuine Progress Indicator (GPI) differ in their focus, with GDP mainly measuring economic output while GPI takes into account social and environmental factors.
Step-by-step explanation:
Gross Domestic Product (GDP) and the Genuine Progress Indicator (GPI) vary from each other because they measure different aspects of a country's economy and well-being. GDP focuses solely on economic output and monetary transactions, while GPI takes into account social and environmental factors such as income inequality, pollution, and quality of life.
For example, GDP may increase if a country's industries produce more goods, even if there is a negative impact on the environment or if the benefits are not evenly distributed among the population. On the other hand, GPI tries to provide a more comprehensive measurement by considering the social and environmental costs associated with economic growth.
