Study Notes
- Population growth remained at approximately 0.002% annually for most of human existence, and was often interrupted by wars, plagues, famines, and natural disasters.
- Population growth rates have accelerated since about 8000 BCE.
- The world population reached one billion in the early 19th century.
- The second billion was added by 1930.
- Subsequent billions were added more rapidly: the third by 1960, the fourth by 1975, the fifth by 1986, the sixth by 1998, and the seventh was expected by 2013.
- 81% of the world’s population lives in Less Developed Countries (LDCs).
- Developed countries and transitional countries have crude birth rates no more than 16 per 1,000, while most developing countries have rates of at least 25 per 1,000.
World Population Growth
- The world population today is 1,860 times the size of what it was 12,000 years ago.
- Around the year 1800, the world population was approximately 1 billion people.
- From 10,000 BCE to 1700, the population grew by approximately 0.04% annually.
- Since 1800, the world population has increased sevenfold.
- Approximately 108 billion people have ever lived on Earth.
- Today’s population makes up 6.5% of the total number of people ever born.
- Data from the UN Population Division provides consistent estimates and projections over the last century.
The Demographic Transition
- A preindustrial, stable population changes to a modern, stable population.
- The transition is a period of rapid population growth between high and low fertility/mortality rates.
- Rapid natural increase occurs in the early transitional stage when fertility is high and mortality declines. Each stage is characterized by birth and death rates.
- Social and economic forces influence the progression of a country from one stage to the next.
- Every country can be placed within the Demographic Transition Model (DTM), but not every stage has a country that meets its specific definition.
Stage 1: High Fertility and Mortality
- Birth rates and death rates are high, resulting in a fairly constant population size.
- This stage applied to most of the world before the Industrial Revolution.
- High mortality rates were inevitable due to lack of modern sanitation, medicine, and industry.
- Socioeconomic groups were small and self-sufficient.
- Food shortages caused by floods, droughts, and warfare were serious due to inadequate transportation.
- Fertility must match mortality for populations to survive.
- Ideology, values, religion, and social structure supported high birth rates.
- Large families were considered a blessing.
- Values and institutions supporting high fertility changed slowly as mortality rates declined.
Stage 2: Declining Mortality
- Modern medicine lowers death rates, especially among children, while birth rates remain high, resulting in rapid population growth.
- Many of the least developed countries today are in Stage 2.
- This stage began in 19th-century Europe.
- Food production increased as agricultural techniques improved.
- Corn and the potato were important crops at this time.
- Improvements in trade, transportation, and communication reduced vulnerability to food shortages.
- Death rates from infectious diseases declined as nutrition and medical science improved.
- Better personal hygiene also helped lower death rates.
- Drainage and land reclamation reduced the incidence of malaria and respiratory diseases.
- Mortality rates decreased about a century earlier in developed countries than in developing countries.
- Today’s LDCs have lowered their mortality rates much more rapidly.
- Low death rates are possible because birth rates create a more youthful population than exists in a stable population.
Stage 3: Declining Fertility
- Birth rates gradually decrease due to improved economic conditions, an increase in women’s status, and access to contraception.
- Population growth continues, but at a lower rate.
- Most developing countries are in Stage 3.
- Stage 3 began in Europe several decades or a century after the beginning of declining mortality in Stage 2.
- In developing countries, stage 3 has followed much more rapidly after stage 2.
- The two primary factors of fertility decline are: organized family-planning programs, and motivating birth control through education, urbanization, modernization, and economic development.
- From the 1960s to the 1990s, the world’s Total Fertility Rate (TFR) decreased.
- In the early 1960s, a number of developing countries began major family-planning programs.
- Fertility also decreases with economic development, modernization, urbanization, and industrialization.
- Low income is associated with high fertility rates.
Beyond Stage 4: A Stationary Population
- Most developing countries will not reach an exact replacement rate before 2020 to 2040.
- Population growth continues after replacement-level fertility has been reached.
- Most developing countries will not have a stationary population until 2075 to 2175.
