Why Does Limiting A Population Space Decreases The Carrying Capacity
The less space there was, the fewer amounts of individualssupported in the environment. Infer: Why do you think limiting a populations space decreases the carrying capacity? There is less space, food, and prey, so obviously the population decreases because therearent enough resources to support a larger amount.
Stage : Delayed Degenerative Diseases
Though degenerative diseases still exist for countries in this stage, medical advances and technology prolong the life expectancy further than countries in the third stage. Delayed degenerative diseases are reduced further as society makes lifestyle changes in health regarding diet, tobacco and alcohol consumption, and exercise.

Chapter 7 Population And Migration
R. Adam Dastrup
Understanding how the human population is organized geographically helps us make sense of cultural patterns, the political organization of space, food production issues, economic development concerns, natural resource use and decisions, and urban systems. Additionally, themes of location, space, place, the scale of analysis, and pattern can be emphasized when studying fundamental population issues such as crude birth rates, crude death rates, total fertility rate, infant mortality rates, doubling time, and natural increase.
Explanations of why the population is growing or declining in some places are based on patterns and trends in fertility, demographic mortality, and migration. Analyses of refugee flows, immigration, and internal migration help us understand the connections between population phenomena. For example, environmental degradation and natural hazards may prompt population redistribution at various scales, which in turn creates new pressures on the environment, culture, and political institutions.
This chapter will analyze population trends across space and time as ways to consider models of population growth and decline, including Malthusian demographic transition, and the epidemiological transition model.

Gender Age And Education
Ravenstein theorized that males were more likely to migrate than females, the longer the distance to relocate. The idea is that men are more likely to find employment than women. For much of human history, this was actually the case. But in the 1990s, gender patterns regarding migration began to change. Now, more women migrate to the United States than males.
Ravenstein also believed that long-distance migration occurred more with young adults, rather than children and elderly. In the United States, over 40 percent of immigrants are young adults. Children make up roughly 16 percent, and elderly make up less than 5 percent of immigration into the United States.
There is a growing concern of unaccompanied minors, between 12 to 17 years old in age, migrating to the United States. The majority of them are males, coming from Honduras and El Salvador because of gang violence.
How Do You Find The Carrying Capacity Of A Population

Where Is It Useful
A constant relative growth rate means simply that the increase per unit time is proportional to the current quantity, i.e. the addition rate per unit amount is constant. It naturally occurs when the existing material generates or is the main determinant of new material. For example, population growth in virgin territory, or fractional-reserve banking creating inflation. With unvarying growth the doubling calculation may be applied for many doubling periods or generations.
In practice eventually other constraints become important, exponential growth stops and the doubling time changes or becomes inapplicable. Limited food supply or other resources at high population densities will reduce growth, or needing a wheel-barrow full of notes to buy a loaf of bread will reduce the acceptance of paper money. While using doubling times is convenient and simple, we should not apply the idea without considering factors which may affect future growth. In the 1950s Canada’s population growth rate was over 3% per year, so extrapolating the current growth rate of 0.9% for many decades is unjustified unless we have examined the underlying causes of the growth and determined they will not be changing significantly over that period.
Structural Changes Of Populations
Before we look at the model used to analyze how populations change, it is essential to look at key factors that influence the structure of a population. A regions population will grow as long as their crude birth rates are greater than their crude death rates. A crude birth rate is the total number of live births for every 1,000 people in a given year. So a crude birth rate of 10 would mean ten babies are born every year for every 1,000 people in that region. Crude death rates are the total number of deaths per 1,000 people in a given year.
The total fertility rate is the average number of children a woman would be expected to have during the childbearing years . The global average for TFRs is about 2.5, but in developing countries, it is as high as 5.0 or higher, and in more developed countries it is as low as 2.0 or less. The total fertility rate is a direct expression of a nations health care system because it reflects a populations access to doctors, nurses, hospitals, and medicine.
The next important term to understand is the infant mortality rate . The IMR is determined by calculating how many children die before the age of 1 per 1,000 live births annually. The highest IMRs are in developing countries where rates can be as high as 80 or more. Conversely, in regions like Europe, it is as low as 5 per 1,000 live births annually.

What Is The Population Doubling Time For A Constant Growth Rate Of 3% Per Annum
The correct answer is arithmetic density. This is because for a country, it is also known as real density and it’s defined as the number of people per unit area of total land in that country.
Thus, the population of a country divided by its area determines its arithmetic density

Stage : High Growth Rate
Around the mid-1700s, global populations began to grow ten times faster than in the past because of the Industrial Revolution. The Industrial Revolution brought with it a variety of technological improvements in agricultural production and food supply. Increased wealth in Europe, and later North America, because the Industrial Revolution meant that more money and resources could be devoted to medicine, medical technology, water sanitation, and personal hygiene. Sewer systems were installed in cities thus public health improved. All of this dramatically caused CDRs to drop around the world. At first, CBRs stayed high as CDRs dropped, this caused populations to increase in Europe and North America. Over time, this would change.
Africa, Asia, and Latin America moved into Stage 2 of the demographic transition model 200 years later for different reasons than their European and North American counterparts. The medicine created in Europe and North America was brought into these developing nations creating what is now called the medical revolution. This revolution or diffusion of medicine to this region caused death rates to drop quickly. While the medical revolution reduced death rates, it did not bring with it the wealth and improved living conditions, and development that the Industrial Revolution created. Global population growth is most significant in the regions that are still in Stage 2.

Doubling time is the amount of time it takes for a given quantity to double in size or value at a constant growth rate. We can find the doubling time for a population undergoing exponential growth by using the Rule of 70. To do this, we divide 70 by the growth rate .
The doubling time is time it takes for a population to double in size/value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time. When the relative growth rate is constant, the quantity undergoes exponential growth and has a constant doubling time or period, which can be calculated directly from the growth rate.
This time can be calculated by dividing the natural logarithm of 2 by the exponent of growth, or approximated by dividing 70 by the percentage growth rate .
The doubling time is a characteristic unit for the exponential growth equation, and its converse for exponential decay is the half-life.

The numbers tell us with a great deal of accuracy where we are now, and how we got here. And they tell us with pretty fair confidence where we’ll be in the near future, because all of the next generations parents have already been born. But the numbers cant tell us for certain where well end up in the long run, because the current trajectories may not remain constant .

Population In South Asia
South Asia has three of the ten most populous countries in the world. India is the second largest in the world, and Pakistan and Bangladesh are numbers five and six, respectively. Large populations are a product of large family sizes and a high fertility rate. The rural population of South Asia has traditionally had large families. Religious traditions do not necessarily support anything other than a high fertility rate. On the other hand, the least densely populated country in South Asia is the Kingdom of Bhutan. Bhutan has a population density of only fifty people per square mile. Bhutan is mountainous with little arable land. More than a third of the people in Bhutan live in an urban setting. Population overgrowth for the realm is a serious concern. An increase in population requires additional natural resources, energy, and food production, all of which are in short supply in many areas.

What Are The Positives And Negatives Of The One Child Policy
The policy has been beneficial in terms of curbing population growth, aiding economic growth, and improving the health and welfare of women and children. On the negative side there are concerns about demographic and sex imbalance and the psychological effects for a generation of only children in the cities.
Future Of Population Growth
As noted earlier, the United States Census Bureau estimates that the world population is roughly 7.57 billion people. Governments and other entities can dramatically influence population change as a way to increase or decrease population growth in a particular country. For example, some countries take dramatic steps to reduce their population. Chinas One-Child Policy dictated that each family could legally have only one child. Families that followed this policy were often given more money by the government or better housing. If a family illegally had another child, the family would be fined heavily. Children born illegally cannot attend school and have a difficult time finding jobs, getting government licenses, or even getting married. Some have reported that the government would force abortions on families with more than one child. One of the significant consequences of this policy was a dramatic increase in abortions and infanticides, especially of females. Female infanticide is linked directly to a global cultural trend that privileges males over femalesbaby boys are desired, especially if the family is only allowed, one child. This specific focus on eliminating women is called gendercide. Half the Sky, written by Nicholas Kristof and Sheryl WuDunn, documents global gendercide and what is being done to combat this problem.
