The majority of people live in the south-central area, which includes the industrial cities of Sao Paulo, Rio de Janeiro, and Belo Horizonte. Urban growth has been rapid; by 2005, 81% of the total population was living in urban areas. This growth has aided economic development but also has created serious social, security, environmental, and political problems for major cities.
Brazil is South America's giant, a dazzling land of pristine beaches, steamy jungles and manic metropolises. Music and dancing are as integral here as eating and sleeping, and you'll find as many regional styles as there are shades of people, from samba's sensual rhythms to Bahia's axé-charged beats.
While it may not be the Eden of popular imagination, Brazil is still a country of staggering beauty. There are stretches of unexplored rainforest, islands with divine tropical beaches, and endless rivers. Then there are the people themselves, who delight visitors with their energy and joy.
When To GoThe weather is worth considering when planning a trip to Brazil, as it can have a significant bearing on how you enjoy certain regions of the country. For example, the Amazon region is one of the world's rainiest places, making travel exceedingly difficult between January and May. Similarly, if you plan to go to the Pantanal, do so during the dry season. The rest of the year, roads are washed out and travel is a nightmare. The south has the most extreme temperatures and during the coldest winter months snow is even possible - but rare.
During summer (December-February) many Brazilians are on vacation, making travel expensive and frequently booked out, and, from Rio to the south, the humidity can be oppressive. However, summer is also the most festive time of year, as Brazilians take to the beaches and streets. School holidays begin in mid-December and go through to Carnaval, usually held in late February.
Brazil's low season corresponds to its winter. Rio temperatures hover around 23°C (73°F), with a mix of both rainy and superb days. With the exception of July, which is also a school-holiday month, this is the cheapest and least-crowded time to visit the country.
