Brazil is characterised by the extensive low-lying Amazon Rainforest in the north, and a more open terrain of hills and (low) mountains to the south, home to most of Brazil's population and its agricultural base. Along the coast of the Atlantic Ocean are also found several mountain ranges, amongst which the highest peak is the Pico da Neblina[?] at 3,014 m. Major rivers include the Amazon, the largest river in the world by volume, the Parana[?] with its impressive Iguaçu[?] falls, the Rio Negro, São Francisco[?], Xingu, Madeira and the Tapajós[?] rivers.
Situated along the equator, Brazil's climate is predominantly tropical[?], with little seasonal variation, though the subtropical south is more temperate and can occasionally experience frost and snow. Precipitation is abundant in the humid Amazon Basin[?], though more arid landscapes are found as well, in particular in the northeast.
After crafting a fiscal adjustment program and pledging progress on structural reform, Brazil received a USD 41.5 billion IMF-led international support program in November 1998. In January 1999, the Brazilian Central Bank announced that the Real would no longer be pegged to the US dollar. This devaluation helped moderate the downturn in economic growth in 1999 that investors had expressed concerns about over the summer of 1998, and the country posted moderate GDP growth.
Economic growth slowed considerably in 2001 - to less than 2% - because of a slowdown in major markets and the hiking of interest rates by the Central Bank to combat inflationary pressures. Investor confidence was strong at yearend 2001, in part because of the strong recovery in the trade balance. Highly unequal income distribution remains a pressing problem.
Four major groups make up the Brazilian population: the Portuguese, the original colonisers; Africans brought to Brazil as slaves; various other European, Middle Eastern, and Asian immigrant groups who have settled in Brazil since the mid-19th century; and indigenous people of Tupi and Guarani language stock. Intermarriage between the Portuguese and indigenous people or slaves was common. Although the major European ethnic stock of Brazil was once Portuguese, subsequent waves of immigration have contributed to a diverse ethnic and cultural heritage.
