An Essay on the Principle of Population

Life expectancy

Population growth

Thomas Robert Malthus

Period 1, Chapter 2 Important Topics Arithmetic and Physiologic Population Density Population Distribution (Dot Maps) Population Data (Census) Population Growth at Different Scales Thomas Malthus RNI, BR, DR, Immigration, Emigration, TFR DTM Population Pyramids Influence of Health Conditions on Population Diseases (Infectious, Chronic, Genetic, Endemic/Epidemic/Pandemic) Government Instituted Policies to Control Population (Expansive, Eugenic, Restrictive) Multiple Choice Explanations B: Japan, none of the other countries have as long of a life expectancy. B: Guatemala because it is a peripheral country in the tropics, which means that the birth rate is high and the average life expectancy is short.

Key Issues Where is the world population distributed? Why is global population increasing? Why does population growth vary among regions? Why do some regions face health threats? Learning Outcomes 2.1.1: Describe regions where population is clustered and where it is sparse. 2.1.2: Define three types of density used in population geography. 2.2.1: Understand how to measure population growth through the nature increase rate. 2.2.2: Understand how to measure births and deaths through CBR and CDR. 2.2.3: Understand how to read a population pyramid. Learning Outcomes 2.3.1: Describe the four stages of the demographic transition. 2.3.2: Summarize two approaches to reducing birth rates. 2.3.3: Summarize Malthus?s argument about the relationship between population and resources.

Population Biology Population Dynamics Principles of Population Growth Exponential growth: as a population gets larger, it also grows at a faster rate (makes a J-shaped curve on a graph) A population cannot grow indefinitely; eventually, factors such as lack of food, disease, etc. will slow population growth (makes an S-shaped curve on a graph) Carrying capacity: the number of organisms of one species that an environment can support indefinitely When a population overshoots the carrying capacity, limiting factors may come into effect Reproduction Patterns Populations are always naturally fluctuating Life-history pattern: an organism?s reproductive pattern Rapid life-history patterns are common among organisms from changeable or unpredictable environments

Chapter 2 Population 1 Population: A Critical Issue A study of population is important in understanding a number of issues in human geography. So our first main issue is a study of population. The Key Issues your book mentions are: 1. Where is the world?s population distributed? 2. Where has the world?s population increased? 3. Why is population increasing at different rates in different countries? 4. Why might the world face an overpopulation problem? 2 Study of Population The study of population is critically important for three reasons: The world?s population increased at a faster rate during the second half of the twentieth century than ever before in history. Virtually all global population growth is concentrated in less developed countries.

4) Define each of the following terms: Demographic transition- Hypothesis that countries, as they become industrialized, have declines in death rates followed by declines in birth rates Demography-the application of principles from population ecology to the study of statistical change in human populations Industrial stage-3rd stage of demographic transition. Birth rates fall b/c children lose their economic value, women have employment opportunities outside of the home and access to birth control. Population growth is reduced Life expectancy-the average # of years an individual in a particular age group is likely to continue to live Natural rate of population change-change due to birth and death rates alone, excluding migration

Population Connection

Overpopulation: The World's Problem by Vince Busam English 12 Period 2 Bradburn 11 December, 1995 The world's population will soon reach a level where there will not be enough resources to sustain life as we know it. Growth must be checked to avoid this catastrophe. Many environmental, social, and economic problems either stem from or are increased in magnitude by the overpopulation problem. With an exponentially increasing population, the problems created by overpopulation grow correspondingly. To ensure population stability not only in the increasingly wealthy third-world areas, but also in the industrialized areas, countries and individuals must work together to achieve zero population growth.
