Population, Migration, and Demography

An exploration of how population growth, aging, and human migration, from ancient trade diasporas to today's labor corridors and climate displacement, are reshaping societies and economies across the globe.

60-Second Review

Express review

A condensed, point-by-point summary of the module, for reviewing right before a test or exam.

  1. World Population Growth and Distribution. World population is nearing its peak, unevenly distributed and shaped by density and the demographic transition.
  2. Fertility, Mortality, and Life Expectancy. Fertility collapse, falling mortality, and a widening longevity divide define global demographic change.
  3. Aging, Policy, and Population Theory. Aging societies, pension strain, and population theory from Malthus to Boserup shape policy debates.
  4. Urbanization and Historic Migration Waves. Urbanization and history's great migrations, from the slave trade to Partition, redrew the human map.
  5. Contemporary Labor Migration and Displacement. Labor migration and forced displacement, from the Gulf to Ukraine, define today's human movement.
  6. Remittances, Policy, and Diaspora. Remittances, skilled migration, and diaspora networks tie sending and receiving countries together.
  7. Demographic Shifts and Food Security. Shifting demographics, census politics, depopulation, and Sahelian food security shape the future.

This is the starting point of Population and Cities of the World: you don't need any prior knowledge of this subject to begin.
