The United Nations estimates ranks Brazil population at position 5 in the world. The latest estimates carried out on the 22nd of March 2016 indicate that the Brazil population stands at 209 million representing 2.83% of the total global population.
Abundance: The population abundance of Brazil in the world is high. Representing 2.83% of the human race, Brazilian are well represented, and their numbers can only increase. Population forecast projects the Brazil population will stand at 215 million by the year 2020. The forecast is a clear indication the Brazil population will continue to grow.
Population growth
Birth rate: The average live births of the country for the past five years is 2.8 million representing 1.4%. During that time, the number of live births has increased on a yearly basis.
Death rate: The average reported deaths in Brazil since 2010 is 1.66 million per year which represent 0.8% of the total population. Just like live births, deaths also increase every year.
Growth rate: The Brazil population growth rate is on the decline for the past five years. In 2011, the growth rate was at 0.96%, 0.94% in 2012, 0.92% in 2013, 0.89% in 2014, and 0.86% in 2015, the latest statistics indicate this year's growth rate is at 0.83%. The slight decline in population growth in the country can be attributed to the adoption of family planning methods.
Population change through migration
The total number of migrants received in Brazil was 3200 people in 2015, and that number has increased in 2016 with 7439 migrants already received by March 24, 2016. Brazil has very few emigrants due to the favorable living conditions in the country. Cases of emigrants are rarely reported.
Age structure and sex ratio
In 2015, the age structure was as follows; the population aged 65+ was 7.8%, the population aged15-64 was 69.2%, and the population aged below 15 was 23% according to the UN estimates.
Population transition
The Brazilian population largely comprise of the young people. The working class population is significantly higher than the dependent population. This has strengthened the economy of the country. Life expectancy has increased while the fertility level has decreased.
Part 2
The rapid population growth in Brazil has influenced the environment negatively. The high population growth is as a result of population momentum since a big percentage of the population is young. An increase in population led to an upsurge of pollution and resource depletion. More arable land is cleared to pave way for new homesteads to be constructed. The percentage of forest in the country has decreased as people clear the field to establish land for farming. As a result, national resources such as fisheries, forests, potable water and arable land have come into critical focus. The decline in water level in rivers, dams and lakes are as a result of deforestation. Unavailability of enough water for consumption together with the decrease of farmland has affected the crop production level. Consequently, affecting the foreign direct investment in the country. Reduction in output level means the country is incapable of exporting more farm produces.
The growth of urban population is also a concern for the environment. Since 2010, Brazil urban population has increased from 82% to 84%. Many unemployed people in the rural areas have moved to the major cities in search of employment opportunities. More industries have been established to absorb the ever increasing number of people moving to the towns. Industrial activities is a major concern for environmental conservation. The disposal of industrial waste into water bodies affect the ecology of marine animals (Roger-Mark, 30). Also, the process of burning industrial waste causes environmental degradation which causes global warming.
