Flashcards

Population Aging

A growing proportion of people in a population are 65 years or older. This is due to increasing life expectancy, improved healthcare, and declining birth rates.

Fertility Rate

The number of births that women have in their lifetime. It's a key indicator of future population growth and is influenced by factors like education, access to family planning, and cultural norms.

Population Momentum

The continued growth of a population even when fertility rates decline. This happens when there's a large number of young women who will go on to have children.

Rapid Population Growth

A population pyramid with a wide base, indicating a large proportion of young people and rapid population growth.

Study Notes

Global Population, Growth, Age Structure, and Urbanization

  • Global population is currently 8.067 billion
  • UN projections for 2050 are 9.7 billion (with a 95% confidence interval of 9.4-10.1 billion)
  • However, it's expected to peak and slow down
  • The largest population growth is in developing countries
  • There is a global aging trend; the proportion of people aged 65+ is increasing
  • Urbanization is increasing, with the rise of megacities
  • Hans Rosling (1948-2017), a Swedish physician and statistician, is known for debunking myths about population growth
  • He co-founded the Gapminder Foundation and was a professor of international health at the Karolinska Institute
  • Population growth was relatively stable until the 17th century but increased rapidly in subsequent centuries
  • Population growth rates are trending downward, and it is expected that in the future they will be below 0%
  • The UN projects the end of population growth around the year 2100
  • Most of the world's population lives in Asia, with significant growth projected in Africa

Size and Growth

  • Historically, the global population growth rate was low, rapidly increasing in the last two centuries, and showing a downward trend
  • Populations of developed countries are expected to start declining
  • China, for a while, was considered the country with the largest population, but now India is reaching that point.
  • The trend shows a possible deceleration in growth rates in several parts of the world

Life Expectancy

  • Life expectancy has increased in the past few decades globally.
  • Belgium, for example, has an average life expectancy of about 80 years.
  • The highest life expectancy is in Japan, reaching about 85 years.
  • Life expectancy in developing countries is significantly lower
  • There was a decrease in life expectancy around 2020-2021 due to the Covid-19 Pandemic

Age Structure

  • Most countries are undergoing an aging process
  • Many countries now see a higher proportion of older individuals than younger
  • The proportion of the population that is 65 years old or older is increasing, and younger demographics are decreasing in proportion.

Fertility

  • The fertility rate measures the average number of births per woman over a lifetime
  • In countries with stable populations, the replacement rate is around 2.1 births per woman.
  • The world fertility rate is currently above 2.1 on average
  • While the rate of births is declining, the number of women of child-bearing age is still increasing globally

Urbanization

  • Urban populations are experiencing significant growth.
  • In many countries, the majority of the population lives in cities, with substantial urban populations in developing regions
  • Large urban areas are growing rapidly (e.g. Tokyo, Delhi, Shanghai), while some areas in Africa have rural majority populations

Impact of the Pandemic

  • The global pandemic of 2020-2021 contributed to a decrease in the life expectancy rates in several countries, and birth rates were temporarily lowered.
  • This is expected to have longer-term consequences on population growth rates
  • A reduction in the size of younger populations is also observed in several regions

Population Policies

  • Policies controlling population growth, such as the one-child policy in China, can have significant consequences on population structure and social/economic factors.
  • They can sometimes lead to an increase in the rate of crime to the neglect of laws, or infanticide

Future Outlook

  • The concept of Carrying Capacity is discussed on the need to understand the sustainable population limits of the Earth
  • The world's population's age and demographic distribution patterns are discussed
  • It's difficult to predict the future of population growth definitively.
