Okay kiddo, let me explain it to you in a way that you can understand. Tamil people are a group of people who speak the Tamil language and come from a place called Tamil Nadu in India.
Now, imagine we have a bunch of toys that are all different colors. If we were to group together all the toys that are the same color, that would be like grouping together all the Tamil people in different cities.
So, when we talk about Tamil population by cities, we are trying to figure out how many Tamil people live in each city. It's like counting how many red toys we have or how many blue toys we have.
To do this, people go from city to city and ask people what language they speak and where they come from. Then they use all this information to figure out how many Tamil people live in each city.
This is important because it helps us understand how many Tamil people live in a certain area and how they are spread out. It also helps us make sure that there are enough resources and services available for Tamil communities in different cities.
Does that make sense, kiddo?
