Explain how economics does apply to both a low-income household and a middle-income household

The low-income households and middle-income households apply in economics because they create demand. Economics refers to the study of production, consumption, and transfer of wealth. Low-income households and middle-income households are the consumers whose consumption is impacted by several economic factors like income levels. Since they affect the demand for services and commodities, they also affect the price of commodities according to the demand curve. Thus, low-income and middle-income house apply in economics since they affect the demand. They are the majority, and their demand affects the aggregated demand.
