Population density and distribution of Brazil.

Extracts from this document...

Introduction

Population density and distribution of Brazil Brazil has a total area of 8,511,965 square kilometres. It is over 35 times larger than the UK and the width of the country at its widest point is almost equal to the distance from London to New York. It has a population density of 19.3 per km3. The distribution of population throughout Brazil is very uneven. Below figure 1 shows the population density throughout Brazil. Areas with a high population density tend to be around major towns and cities. More than 40% of the total population live around in the Southeast, but however this land is only 18% of the total area. This means that a large are of Brazil is thinly populated. Humans very thinly populate the large area of the Amazon rainforest but it does however have the largest natural reserve of wild animals in the world. Figure one also shows a distinct pattern in the population density throughout Brazil. Over 90% of the population live near the coast, mainly in the South East of the country. ...read more.

Middle

They migrate for a number of reasons firstly there a many more jobs in this area and the rate of pay is higher than in other rural areas. Rural areas such as the North East suffer from environmental difficulties such as extreme droughts, which make it difficult for them to farm. People in cities also tend to live longer due to the better conditions and medical care. However the quick growth of the cities has put enormous pressure on housing and on public services like water supply, sewerage, health care and education. The number of permanent houses is growing rapidly in urban areas. Even so, for many of the newcomers and young people growing up in the cities, it is difficult to find somewhere to live. They cannot afford to buy or rent permanent housing, so they often finish up living in shantytowns (see figure 3) called "favelas" in Brazil. Shantytowns are common in other industrialising countries of the world where people are moving to cities in search of better living. ...read more.

Conclusion

Hydro electricity is an important industry in Brazil as 90% of its electricity is produced this way. Projects to set these sites up were funded with money borrowed from other countries in the 1970's. The population however in Brazil is steadily increasing in 1980 the total population was 119 million and in 1995 it was 155.82 million. There are a lot of young people in Brazil 62% of the population is under 29 and 44% under 19. This means that the population is likely to rise even more in the next 10 to 15 years as these women will reach child bearing age and the average women is Brazil bears an average of 2 children. However in the past this number was an average of 6 in the early 1990's, but as Brazil has become a more economically developed country this number has decreased with improved contraception and education. However before because of poor medical care it was unlikely that all 6 children would survive into their teens so it was necessary to give birth to a large number of children. ...read more.

    There are a number of factors that contribute to the relative warmth of cities: * During the day in rural areas, the solar energy absorbed near the ground evaporates water from the vegetation and soil. Thus, while there is a net solar energy gain, this is compensated to some degree by evaporative cooling.

    This is because the area has a positive relief of lowlands and gently undulating terrain with the soils being fertile and easily worked e.g. loams and alluvium.

    For example 20% of Brazil's land is only occupied by approximately 3% of it's population. The 1980's curve has only changed slightly in 20 years. Now the curve is moving more towards Lorenz's curve, which implies that slowly more people are spreading out of the densely populated areas.
