Population growth- refers to the change refers to a change in population size. It can be a positive or a negative change
When there is no change in population numbers, it is known as Zero population growth.
1) Better medical and heath care
2) More births than death
3) Increased food supply with help of technology
Birth rate- Number of live births per 1000 people per year
Death rate-Number of deaths per 1000 people per year
Natural increase- Birth rate-death rate
Population distribution
(Kaya spread analogy)- the way people are distributed over an area of land- people/square kilometer
FACTORS
1) Physical environment
• People tend to live in areas with fertile sol and non-extreme climate.
Eg. River deltas because sediments can make soil

2) Higher demand for housing
• Competition for housing, especially in cities of less developed countries which do not have sufficient housing for its growing population
• People resorting to living in slums and temporary shelters (squatter settlements)
• Such settlements have overcrowded living conditions and do not have electricity, clean water & sanitation which will result in spread of diseases
Eg. India (cardboard houses and huts) or Mexico
3) Higher demand for education
• With more babies born each year there needs to be sufficient schools to provide a basic education
• Less developed countries may lack the funds to build schools or hire teachers to educate the young
• Thus, not many people are able to attend school and get an education
• Without education, it is difficult to get out of the cycle of poverty
Eg. Nigeria 4) Higher demand for jobs
• Stiff competition for jobs as there are only a limited number of jobs available and this results in high unemployment rates and crime rates such as robberies as jobs are
As a result, the community growth intensifies to a point where the income per capita will be so low that its maintenance would turn into untenable; hence the population suffers and contracts, occasioning a new cycle again. Therefore, the theory emphasizes a rigid dependence of population growth upon the food supply.
Population continues to grow and is expected to reach an all time high in future years. There are tons of different reasons for why population is rising so quickly. In document d, it says, "Every second 5 people are born and 2 people die, a net gain of 3 people. This fact from document d shows one reason why population growth is at all time high. Document d, also states "At this rate, the world population will double every 40 years and would be 12 billion in 40 years, 24 billion in 80 years, and more than 48 billion in 120 years." This will create tons of difficulties, like the amount of food and supplies needed for the world, which will make it nearly impossible for supplies to keep pace with the population growth. Document a shows
There are three main factors that fuel rapid population growth in the world. Firstly, the increased production and distribution of food has now enabled more people to live longer lives. Initially, starvation caused high death rates, therefore inhibiting population growth. In our modern society, there is an abundance of food to feed the population. Improved distribution channels have enabled food to reach into dry places, thereby eliminating the risk of starvation. Secondly, there is an overall improvement of public health care. Poor sanitation and lack of clean water were the main causes of deadly diseases like malaria. These diseases often wiped
Have you ever considered how your mother birthed you, going on you in her paunch for nine months in progression, losing her flawlessness even to the point wherein her always breaking points are continually up in context of you. in any case, in the mediating time always welcoming the main thing that she is passing specifically in the judicious world. That is not how China longings it 's mothers to be. China has dependably been one of the extraordinary nations as of late as its standing huge inconveniences in later years is overpopulation. China 's human advancement has been a vital trouble. In China, all nationals are being learned that them are influenced to the measure of kids they may convey. The office made a way of development called "one
“An Essay on the Principle of Population” is written by Thomas Malthus where he outlines his theory on population growth. He thought that if population continued to grow, food production wouldn’t be able to keep up with demand and he believed that many people would die due to famine. Either people would have to use more contraception to drop the birth rate, or the death rate would increase due to wars, disease or
Low- income children 's school districts often lack the money to provide these children with resources, and therefore the children will not get these resources any other way. Devarics (2011) stated, "Only 22 percent of local districts reported offering pre-kindergarten or other early learning programs for low-income children" (para.8). Denying this resource affects the many children who reside where that 78 percent of local districts do not offer pre-kindergarten, because many go to kindergarten not knowing minimal skills required. As a consequence, this postpones their education even further. Moreover, Davarics (2011) also stated, "Many schools aren 't educationally where they need to be, which ultimately means many students won 't graduate ready to succeed in a career or in higher education," (para.11). Many low-income schools do not offer activities such as, art, music or sports, because of the lack of money, facilities, or staff. They are not supplied with the right tools and have poor access to computers and Internet. They also do not offer rigorous courses at many of these schools, and have less qualified, trained, and less experienced staff that cannot proficiently teach such courses. Going to school with these disadvantages, can make these children unmotivated to continue an education where there will be little educational progress.
Today, in American society, many people believe that being overweight is unhealthy, but back in the 1700’s, being overweight was what every person wanted to be. In the 1700’s, having a little extra weight showed that that person had good food and was therefore more likely to survive. Before the 1700’s, many people in Europe died from starvation and disease, resulting in little population growth. During the 1700’s was when that all changed. The population increase in the 1700s to 1800s was due to a declined mortality rate caused by changes in Europe’s economy, society, and culture.
The lack of fundings for schools plays a huge factor in children 's education. In my
Housing in inner city areas was poor quality and in a 1991 census it was found that over 1 million homes in the inner cities still lacked the basic amenities of bathrooms, WC’s and hot water. The occupants have low incomes and are often elderly, young

With Australia’s population rapidly nearing 23.5 million people, the issue of sustainability and the number of people Australia can allow to live comfortably without significant damage to the surrounding environment is extremely important. The misconception that Australia is underpopulated with plenty of room to accommodate the worlds rising population is widespread. With the majority of Australian land being arid and inhospitable, finding available land and resources to accommodate a rising population is placing a huge amount of pressure on the Australian environment. Australia’s population growth consists of two main components; births minus deaths and net migration. While Australia’s birth rate sits at 1.9, lower than the 2.1 needed to replace our aging population, our expanding population comes from overseas migration accounting for around 60 per cent of our growth (Department of Immigration and Border Protection). Currently the total migration rate is set at 210,000 people per year making Australia’s population quickly on the rise. This poses an important discussion regarding the impacts of such a rise and if there is a specific number that constitutes a sustainable Australia regarding population. The issues that may come to pass as a result of overpopulation are great and varied. These include and are not limited to; resource shortages, social conflict, overcrowding, pollution, habitat and biodiversity loss and a lowering in national health standards. The Australian Conservation Foundation (ACF) has put forward arguments opposing a rising population due to the predicted environmental damage we would face as an outcome. A few of the main problems associated with an unconstrained population are outlined in this essay.

An increase in human population can influence our economy. Some of the factors that are affected are unemployment, poverty and the restriction of economic expansion. When the population increases, the cost of health, education, and other areas of urban growth are affected. Unempl...
Seven and a half billion. Enough steps to walk around the globe a hundred and sixty times. Our planet is trying to provide and sustain for a colossal number of people which is expanding every single second. Now the concern that has been put forth by scholars come from the idea that the consumption and effects to our planet by our current society is an international security risk that greatly compromises the future generations. Confucius even mentions this at the earliest start of civilization by saying:
Economic growth is one of the most important fields in economics. In current generation economic is developing well. Economic growth is really important to country and for the world as well. Economic are one of the identity for country because it shows a country development and attraction for other countries (F, Peter. 2014). For example well economic develop such as Singapore, Dubai, New York, and Japan. These countries are well develop and maintaining their economic growths. Economic growths are really important because higher average incomes enables consumers to enjoy more goods and services. Then, lower unemployment with higher output and positive economic growth firms tend to utilize more workers creating more employment. Enhanced public
