Government budget deficit

A government budget deficit means that the government spends more money than it earns in a year. That means the government has to borrow money from other countries or banks to make up the difference. It's kind of like when someone spends more money than they have in their bank account. The government has to make sure they don't borrow too much or they won't be able to pay it back.
