Population in Brazil:

Population Distribution in Brazil

  • Brazil is the most populous country in the South American continent. According to Census 2010, Brazil ranks fifth in the world with a population of around 19 crores. It is also the fifth largest country in the world in terms of land area. Brazil has 5.6% of the world's land area and 2.78% of the world's population. As a result, the population density is around 23 people per square kilometre.
  • Brazil's population distribution is highly uneven. The majority of Brazilians have concentrated within 300 kilometres of the eastern coastal plain. As a result, agriculture and industry have thrived. As a result, there is a higher population density here.

    Population density in Brazil

  • The Amazon Basin's interior, on the other hand, is sparsely populated. Climate, heavy rainfall, inaccessibility, and dense forests are all obstacles to human settlement development here. As a result, settlements are limited to a few areas of the Amazon basin.
  • The central and western parts of Brazil are less populated. Brazil's highlands have a moderate population density.

Example

Observe figures and answer the questions.

  1. In which area is population greatly concentrated?
  2. In which area is the distribution of population sparse?
  3. Prepare a note on factors responsible for
    the uneven distribution of population based
    on study of Brazil you have made so far.
  4. Identify the type of map showing distribution.
  1. Population is greatly concentrated in the south eastern part of Brazil.
  2. The Amazon Basin in the nothern part and the central and western parts of Brazil have sparse distribution of population.
  3. The distribution of population in Brazil is uneven:
    i. There is sparse population in the Amazon Basin due to hot and humid climate, heavy rainfall, dense forests, inaccessibility.
    ii. The population is low in the swampy areas of Pantanal.
    iii. Low population is found in the central and western part of Brazil due to lack of minerals, low rainfall, hot and dry climatic conditions.
    iv. The distribution of population is moderate in Brazilian Highlands.
    v. High population is found in the coastal regions and the southern part of Brazil. This is due to flat fertile land and abundant availability of minerals due to which agriculture, industries and trade have developed.
  4. The type of map showing distribution of population is a dot map.
