Study Notes

World Population Growth

  • World population has grown significantly from 1 AD to the present, showing a dynamic pattern.
  • Population growth accelerated during the Industrial Revolution, influenced by increased food production and advancements in science and healthcare.

Factors Driving Population Growth

  • Increased Food Production: Advances in agriculture (machinery, fertilizers, new crops) allowed for more food to sustain a larger population.
  • Scientific Developments: Scientific progress, disease control, and improved sanitation reduced mortality and increased overall health.
  • Improved Healthcare: Access to medical care, vaccinations, and treatments increased life expectancy and reduced death rates.

Birth and Death Rates

  • Birth Rates: The number of newborns in a specific area over a given time. High birth rates contribute to population growth.
  • Death Rates: The number of deaths in a particular region over a set period. Low death rates indicate a healthy population, while high rates may signify challenges.
  • Population Growth Rates: A positive growth rate means births exceed deaths, leading to an expanding population. A negative growth rate indicates more deaths than births, leading to a decline in population.
