A child growing up in the city has the advantages of a lot of interesting and exciting place to visit. He or she can go to the zoo, museum, art galleries and concerts. There are a lot of restaurants with different kinds of food. It’s easy to see every new movie that comes out. Child in the country don't have a lot of these activities nearby.
All in all, I think a childhood in the city is better because it prepares you more for what real life is like.
