Which term is characterized by an economic decline lasting six quarters or longer?

The term that characterizes an economic decline lasting six quarters or longer is "depression." A depression is a prolonged period of economic downturn that goes beyond the typical duration of a recession, which is usually defined as lasting two consecutive quarters or more. During a depression, the economy may experience significant reductions in consumer spending, business investment, and overall economic activity, leading to higher unemployment rates and widespread financial distress.

Understanding the characteristics of a depression is crucial, as it helps differentiate it from other economic phenomena. For instance, a recession can be sharp and brief, while a depression suggests a much deeper and longer-lasting economic contraction. Therefore, recognizing the distinctive features of a depression, especially the extended timeframe of six quarters or more, is essential for grasping the severity of economic challenges that may arise in a country's financial landscape.
