The Rate Of Population Growth

The world population of 7.2 billion in mid-2013 is projected to increase by almost one billion people within the next twelve years. It is projected to reach 8.1 billion in 2025, and to further increase to 9.6 billion in 2050 and 10.9 billion by 2100. This assumes a decline of fertility for countries where large families are still prevalent as well as a slight increase of fertility in several countries with fewer than two children per woman on average.

Global population; it’s what has been mystifying and engaging our human geographers for centuries. In fact, the various stages of the demographic transition have shown what the population is acting as now, and how it will change in the future. Starting right here in the United States, we are having a very successful time maintaining a small growth population. Our 1.83 child per woman ratio is slightly below the zero growth 2.03, but our population continues to grow because of our governmental decision to approve immigration into the country. Because of this vital decision, it allows our population to continually grow. Now, back to the demographic transition stages. The United States is currently in Stage 4 along with many other Developed European

For many years it has been thought that the maximum human population would be determined by the amount of drinkable fresh water. Earth can only hold, manage, and support so many people. This is called carrying capacity. If we go over this carrying capacity it could cause worldwide issues with the environment along with many other issues. For example if the human population goes over the carrying capacity of the earth then problems like lack of clean drinkable water, lack of land that humans could live on or occupy, and lack of available jobs could become much more serious and have terrible effects on the system which everything works.

Over the past years, there has been an exceptionally large national increase which has caused several population issues. These issues include: homelessness, deforestation and more fields being used to make space for shops and houses disrupting the biodiversity growth. Problems like this are caused when there is an abnormal increase in the birth rate where more babies are born; this is also known as a ‘baby boom’. This can occur when nations have more children as a whole and events like this normally takes place after an achievement – an example being when we won the World War Two. The country was relieved that the fighting was over so their instantly celebrated which is why more children were born. In the last 50 years alone, the population has doubled showing just how fast the population is actually growing and even though it may seem fortunate that there are less recorded deaths, this makes the Economical

There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? Population changes are due to the relationship between births and deaths. If the number of births equals the number of deaths then the world’s population will remain the same, but if births exceed deaths, population growth will occur. Early in history, population was slowly growing because of high death rates related to wars, famines, and poor medical services. With advances in

In the status quo, population growth is inescapable. With the current population at seven billion and the estimated population to be ten billion in the year 2050, our basic needs will become harder to obtain. For example, water supplies are already scarce and countries in poverty do not even get clean water sources compared to the first world countries. In thirty years, water will suddenly not turn abundant because there is a limited amount of freshwater which is only three percent of the total amount of water. The demand for food is also going to

Birth rates worldwide have been falling. In 2000, the birth rate was twenty two births per one thousand people (Indexmundi.com). This number is the crude birth rate and is used to gauge population

In developed countries the birth and infant mortality rate is lower than developing countries. With the developing countries having a higher birth rate they also have a higher infant mortality rate. It is difficult to predict the earth’s population growth because of the different stages a country might be in, or how fast they move from one to another. Stage one is preindustrial, this is when the birth rate is high but so is the death rate so the population is low. Stage two is the transitional stage where the birth rate is still high but health care has gotten better so the death rate has decreased and the population is skyrocketing. Stage three is the industrial stage this is when the birth rate is still increasing even though the death rate has stayed the same making the population still increase. In the final stage postindustrial the birth rates are very low because of birth control and people desiring smaller families. The death rate is still how and the population slowly

As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.

Consider that Earth’s population is projected to rise to 10 billion by the year 2050. The current

The article by Dennis Dimick brings up some very good points about the increasing population. He states that with our current population of 7 billion people, we currently do not have enough food to eat. With the population increasing day-by-day, we will face more shortage in the future. He also brings up the issue of natural resources. We are currently using so much natural resources that we will run out very soon. The use of natural resources tend to increase with increase in social standing (wealth).

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.

According text one, Population Trends between the years 1700, to an estimated 2100 as the years go on, the global population size continues its rise. For example, in the data it can be seen that the global population went from .68 billion individuals in 1700, to a predicted 9.46 billion by 2100. Also, the life expectancy increased from 27 years in 1700, to a predicted 81 years by 2100. (Ronald Lee,

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).

One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will
