Gravity model of migration

Hey there kiddo, do you know what gravity is? Well, you know when you throw a ball, it always falls back to the ground? That's because of gravity. It's what keeps us grounded to the earth so that we don't float away into the sky.

Now, imagine that people also have their own kind of gravity. They are attracted to certain places, just like how a ball is attracted to the ground. This is where the gravity model of migration comes in.

The gravity model of migration is a way of predicting how many people will move from one place to another based on how close they are and how attractive the new place is. It's like predicting how likely someone is to visit a new toy store that's close by.

This model takes into account two main factors: distance and size. The closer two places are, the more likely people are to move between them. And the bigger and more attractive the new place is, the more people will want to move there.

For example, if there are two cities, City A and City B, and City B is twice as big as City A, then we would expect twice as many people to move from City A to City B as from City B to City A.

This model is very helpful because it can help us understand why people move and where they are more likely to go. It also helps governments and organizations plan for the future and make decisions about how to allocate resources.

So, that's the gravity model of migration - it's like predicting how likely a ball is to fall to the ground, but for people moving from one place to another.
