Let's imagine a big playground with many children playing. The playground is the European Union, and the children are the people who live there.
Now, to make things fair, we divide the playground into smaller sections, so every child has a specific area to play in. These smaller sections are what we call electoral districts.
Every electoral district has a particular number of people living in it, and they are grouped by where they live, their age, and other things that make them similar.
For example, in one electoral district, there might be a group of people who are all over 18 years old, while in another electoral district, there might be a group of people who all live in the same area of the country.
The purpose of these electoral districts is to make sure that everyone's voice is heard equally. In elections, people can vote for someone to represent them in the government.
By dividing the playground into smaller areas, it makes it easier for people to choose someone who understands their unique needs and concerns.
So, just like how you might choose to play with a certain group of children on the playground, people in the European Union get to choose who represents them based on the electoral district they live in.
