Define a budget deficit in an economy/country and the result of having that deficit.

A budget deficit refers to a condition in which a company's or business's expenses exceed the available income indication a negative financial condition of a company or business. A budget deficit is caused by improper planning and analysis of anticipated expenses within a given period.

The result of a budget deficit is debt. A country's overall spending should be sustained by a country's available or generated income. If its spending rises higher than its revenue, the country will engage in debts to maintain its daily activities and operations. This will also lead to an increase in the national debt owed to the future of a particular country, its future operations, and its citizens.
