Describing known biases/imbalances of a dataset

For example, suppose I have a dataset with data about humans, and I know there is a gender imbalance in the dataset - say it's 70% women and 30% men. Users of the dataset should be able to be informed about this imbalance before using the dataset for training.

Is there a way to capture this information using Croissant? Either as structured data, or just as text under a particular property.
