Growth in a time of debt is when a country or a business is able to grow, even when it has a lot of debt. This means that the debt is not damaging their ability to grow and become larger.
Think of debt like a challenge. It is like there is a big mountain that a country or business needs to climb, but with hard work and smart strategies they can still grow while they are climbing. It isn't easy to do, but it is possible with some help.
Sometimes different levels of government can help by providing money or support to help the country or business. This helps them climb the debt mountain, and reach a stronger, more prosperous position.
