How Do Cities Grow and Shrink Over Time?

Cities grow when lots of people move in to find jobs, and they shrink when people leave because there aren't enough jobs or money. It's like a big game of tag, if more people join the game, the city gets bigger; if more people leave, it gets smaller.

Why People Move In

Sometimes, new factories, schools, and hospitals make cities more attractive to live in. Imagine getting a new toy that everyone wants, that's like having a new factory or hospital in the city!

What Makes Cities Shrink

When there are not enough jobs or money, people leave for other places where they can find work. It’s like when you don’t want to play tag anymore and go somewhere else.
