Population Growth

Abstract: In 1900, the world's population was approximately 1.5 billion. Since 1960, world population has grown by approximately 5.5 billion people. Given current fertility levels and growth rates, global population is expected to reach 9.7 billion people by 2050. Historical processes of global population growth also need to be understood in relation to regional differences in population growth and the prospects for future population change. Changing patterns of population growth have also been the subject of considerab… Show more

“…Beyond explanations based on aggregate individual‐level characteristics, recent scholarship has increasingly noticed the role of context in demographic processes. After all, population geography studies the location and spatial processes on demographic outcomes (Newbold, 2021), but little is known about how one's spatial location in the ethnic context may influence her fertility behaviours. The current study argues that the formative causes of fertility is context contingent and cannot come into effect via individual behaviours alone.…”

“…It is increasingly realized that technical skills alone are insufficient to tackle the complex issues and challenges we face in the 21st century. The global population is expected to reach 9.7 billion by 2050 (Newbold, 2016), a 61% increase in only 50 years, putting greater pressure on freshwater resources. Many parts of the world are already experiencing water scarcity, and the situation is expected to worsen in the coming decades due to climate change and water quality degradation.…”
