Population Growth
Population growth is the increase in the number of individuals in a population over time. It is influenced by factors such as births, deaths, immigration, and emigration.
Case Studies
For example, the population of India has been steadily increasing over the years, leading to concerns about resource scarcity and sustainability. In contrast, Japan’s population is declining due to low fertility rates and an aging population.
Population Density
Population density is the number of individuals per unit area, such as people per square kilometer. It impacts social infrastructure, resource allocation, and environmental sustainability.
Statistics
According to the United Nations, the world population is projected to reach 9.7 billion by 2050, with significant growth in Africa and Asia.
