Classification is important—in any discipline. Classification of symptoms helps doctors determine the correct treatment for patients. It helps us pick out the right book in a library, settle on the appropriate sentence for a convict, and compare species of plants. For similar reasons, researchers collect countries into groups based on a variety of metrics that define prosperity. These systems allow us to compare gains in development, to better understand how gains in development can be achieved, and determine appropriate aid packages. It isn’t always easy because there isn’t any one parameter that successfully defines wealth or prosperity.
