Prevalence

Prevalence is a big word that means how common something is. It’s like asking, “How many people have this thing?”

For example, if we want to know the prevalence of people who have blue eyes in a classroom, we could count how many people have blue eyes and then divide that number by the total number of people in the class.

Prevalence is important because it helps us understand how widespread something is, whether it’s a disease or a physical trait. If we know how many people have something, we can plan and prepare for it. We can also try to figure out why something is so common or if there are ways to prevent it from becoming more prevalent.
