Population Geography

Population geography examines the spatial distribution, composition and dynamics of human populations and the interaction of these patterns with economic, social and environmental processes. It encompasses the study of fertility, mortality and migration across scales—from neighbourhoods and cities to regions and the globe. Key themes include the formation of urban systems, the impacts of demographic change on resource use and landscape transformations, and the role of mobility in shaping social and economic networks. Contemporary research highlights the uneven distribution of population growth, the mounting influence of ageing societies, and the environmental consequences of human movements. By integrating demographic data with geospatial analysis, population geographers reveal how patterns of settlement, mobility and change influence planning, policy-making and sustainable development in a rapidly evolving world.

Studies of intercity flows during China’s Spring Festival have uncovered a nonlinear relationship between distance and migration intensity. Using machine-learning algorithms on mobile big-data, research identifies three distance-decay regimes—plateau, drop and rebound—showing that coastal regions exhibit weaker decay and more inclusive mobility patterns, while inland areas concentrate flows more locally. These insights challenge traditional monotonic decay assumptions and call for transport and land-use policies that reflect regional heterogeneity.

Analyses of daily mobility and longer-term relocations during the COVID-19 pandemic in Santiago, Chile, demonstrate distinct socioeconomic responses. Mobile-phone data reveal that lower-income areas experienced relative increases in daily movements, whereas relocations rose mainly among higher-income groups. Contrary to expectations of counter-urbanisation, no clear preference for rural destinations emerged, emphasising the need for nuanced policy responses to mobility shocks that account for income differentials and urban resilience.

Global migration flows have been linked to carbon transfers through complex-network analysis and regression on demographic, affluence and technology variables. Estimates show that a 1 per cent rise in migration correlates with a 0.12 per cent increase in embodied carbon flows, with male migrants tending to generate higher impacts via intermediate products. This work underscores the importance of migration policy in carbon-management strategies.

Domestic migration in China has been quantified in terms of carbon footprints and aligned with 1.5 °C climate pathways. Consumption patterns of rural-to-urban migrants average 2.3–2.6 tonnes CO₂e per person annually. Under shared socioeconomic projections, high-emitting migrants must reduce emissions substantially to stay within carbon budgets, highlighting the need to integrate migrant lifestyles into mitigation plans.

In eastern Africa, refugee-hosting communities experience intensified deforestation and pollution due to increased reliance on firewood, charcoal and coal. Cointegration and causality analyses demonstrate unidirectional links from rising refugee populations and traditional energy use to environmental degradation. These findings call for long-term environmental policies that address energy needs in humanitarian settings.
