Answer:
The reason why the concept is contested is because it is difficult to establish objective parameters on which to base the measure of how developed a country is or not.
Step-by-step explanation:
To measure development, many indicators have been proposed, like GDP, GDP Per Capita, Poverty Rate, Unemployment Rate, Energy use, etc. However, economists and social scientists do not agree on which of these indicators are more important than others, or on which should be used.
The most appropriate definition for development would be: 'the process in which a community, a district, a city, or a country improves the economic and social well-being of its inhabitants or members".
