Ethnic segregation is when different groups of people who come from different cultures and look different from each other live apart from each other. This means that they don't live in the same neighborhoods or go to the same schools. Instead, they live in different places where everyone mostly looks and acts the same.
It's like if you were in a classroom and you only sat with people who had the same hair color as you. The people with brown hair would sit on one side and the people with blonde hair would sit on the other side. This is ethnic segregation on a small scale.
When ethnic groups live separately, they may not have the same opportunities or resources as other groups. For example, one group may have access to better schools, jobs, and healthcare. This can make it hard for people in other groups to succeed and thrive.
It's important to remember that everyone is different and diversity should be celebrated. We can learn a lot from people who come from different backgrounds and we can make the world a better place when we work together.
