Brazil is a country where there's a huge difference between the lives of the rich and the poor.
Raphael is 13-years-old and has lived in Doña Marta favela in Rio de Janeiro his whole life.
Favelas are poorer areas of housing in Brazil built on the edge of big cities.
They're hard to get into and out of, because they are built on the steep hills and have busy alleyways.
Leah's been to visit Doña Marta to see what it's like to live in a favela.
Raphael tells her about how the area's changed in recent years, saying his favela is now a safer place to live.
