An imbalance occurs when things are not equal or fair, like too much weight on one side.
When we talk about an imbalance, usually we mean that something is out of proportion. Imagine your favorite coffee shop changing their menu to only have a few expensive drinks and a bunch of cheaper ones. They might be worried they're losing customers who want a more balanced selection of options. The shop owner could try to balance the menu by adding some middle-range prices or removing some of the cheapest drinks.
The word "imbalance" can also refer to an unfair situation where one side has too much power or influence, like if there's an imbalance between rich and poor people in a society.
The property of not being in balance.
Example: The growing imbalances between the rich and poor first lead to more crime.
