Okay kiddo, so you know how sometimes people move from one place to another to find a better life? Economic migrants are people who leave their homes and go to a different country to try and find better jobs or a better economy.
Sometimes people move because there isn't enough work where they live or they can't make enough money to support themselves and their families. When people move to a different country for this reason, they become economic migrants.
Some countries are better at providing jobs and opportunities than others. That's why people move to places where there are better job or educational opportunities so that they can have a better life.
But moving to a new country can be hard. You have to learn a new language, find a new home, and get a job. Sometimes people face discrimination or have trouble adjusting to their new surroundings.
It's important to remember that economic migrants are just people looking to improve their lives, like you and me. We should try to be kind and welcoming to everyone, no matter where they come from.
