Factors Influence Population at Both a Local and Global Scale.

First of all, the demography is the study of human’s inhabitants. The population change over time because childbirths, deaths, and migration. Also, the population size can be reflecting by fertility, mortality, and migration. The fertility is the ability of women to product healthy offspring in abundance. On other word, it is the ability of a women to get pregnant. However, fertility depends into feelings, way of life, food habits, and take alcohol and other drugs. In demography, there are measures for fertility which is the crude birth rate and it is every twelve months’ quantity of live births for each thousand people in a population. The second thing that affect population size is mortality which means the quantity of death in inhabitants

Population increased due to more immigrants and natural increase. The immigrants coming into the continent increased as well because of push and pull factors. Push factors are bad events like war, disease, religion, teeny, taxes, poverty, or no jobs. Pull factors are good events like available land, money opportunities, freedom of religion, jobs, medical care, and democracy. Natural increase is where the population increase because with available medical care now the life expectancy increases, less die due to sickness, and more babies are born.

Availability of resources: Regions with an abundant supply of natural resources such as oil, raw metal, and wood tend to have a high population density because places with more resources often have a better standard of living. (Spatial Significance: The availability of resources is a major factor in where people live. People tend to live near places rich in resources to survive. Without much resources, the life expectancy will be lower than places with much resources).

Population is also based on size, age structure, density, sex ratio, and fecundity. The different size of population tends to, or can have a major impact on any economy. The size and density dealing with a population are the two most important issues scientist use to understand,

My best guess is India will have the highest population density because they are industrializing quickly, have plenty resources and are working to get more and also they have lot of job opportunities. In other places it does seem like there will be much industrialization such as Africa which can cause the people to die out when they do nt have resources. Also the culture in India from what I have seen is that people have many children and encourage big families and take care of each other.

Population growth has a huge bearing on the culture of a society because people bring with them their way of lives when they move to a new place. 70 % of the annual population increase in the United States is attributed to growth in immigrant populations, whether from newcomers or from the expansion of existing populations. Immigration

The Global human population increases growth amounts to around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing, and estimates have put the total population at 8.4 billion by mid-2030, and 9.6 billion by mid-2050. Many nations with rapid population growth have low standards of living, whereas many nations with low rates of population growth have high standards of living.

Northern cities such as Belem and Porto Velho have seen a big increase in population

The Demographic environment relates to the structure of populations (Oxford Dictionaries | English, 2017). The factors that contribute to the demographic environment relevant to this report are location and density of the population.

Brazil, like many Latin American nations, is a country undergoing rapid change. The nation’s push to transition from newly industrialized to develop country has forever altered Brazil’s physical geography, level of development, and economic activity.

While it may be observed that the exponential rate of growth is slowing, the world population is still growing rapidly. Perhaps the biggest concern is not the actual population increase but the distribution of the growth (Wilson, Population).

For example, urbanization leads to dense populations. Densely overpopulated populations, while socially stimulating have higher chances of spreading infectious diseases. This is because the vector can easily spread when hosts are in close proximity. Think about the Ebola outbreak, a virus that used to be controlled when it occurred in small villages was able to spread fast when it reached dense populations . How does these countries/communities differ in population density? In terms of altitude levels, reports have suggested that Ae. Aegypti is rarely present in areas with elevations between of 1,700–2,100 m (Martin Cetron). Suggesting that altitude levels influences transmission and mosquito survival. Mosquito’s vectors require suitable habitants (temperature, precipitation, vegetation and human population density) in order for the vector to be present. Such habitant differs among countries and affects the mosquito

When there’s too many people living in one place it causes things to become troublesome. If there is too many people in one country, then crime will go up. “There's a big increase in crime as density

All over the world, the human population fluctuates throughout each country due to several different factors. Some of the factors that can lead to an increase or decrease in population include industrialization, economic instability, poverty, laws, disease, resource destruction, sanitation, natural disasters, birth control, and access to education (Class notes). Although population decline is possible and relevant in some countries, the more important issue facing many countries today is overpopulation. Some over population problems include decreases in food sources, housing needs, land, increase in distribution problems, decrease in job availability, and poor health care environment (HowMany.org, 2014). One important question related to controlling

Stretching over 2,500 miles form east to west and 2,700 miles from north to south, Brazil is the world’s largest tropical country. The only nations that are larger are the lands of Russia, Canada, China and the United States. Brazil has more then 150 million people spread unevenly over its huge land area, making it the fifth most populated country in the world. (Encyclopedia.com) More then two thirds of Brazil’s people live in the cities and towns and more then 29 percent of them are in the ten cities with more then a million people. These include the metropolitan area of Sao Paulo with more then 15 million people and Rio de Janeiro with more then 9 million people. The rural population is mostly concentrated on the East Coast or
