The biggest favela in Brazil, called Rocinha, is in Rio de Janeiro's South Zone. Around 200,000 people live there, but the exact number isn't clear because it's grown so quickly and housing isn't formally registered. Rocinha is known for being packed with people, yet it's full of life with a lively community. It has its own bustling economy with lots of small shops, businesses, and services that serve both the residents and visitors. https://pbs.twimg.com/media/GXdLkZ4WUAASU3r.jpg
