Middle-Class Consumption Growth
The projected growth in middle-class populations within emerging superpower nations, which will drive increasing demand for resources including rare earths, oil, staple grains and water, with significant consequences for resource availability, cost and the physical environment.
Real World
India's middle class is projected to reach 1 billion people by 2047; rising incomes are already driving a surge in car ownership and meat consumption, increasing India's oil imports and placing strain on freshwater supplies used for livestock feed.
Exam Focus
Quantify the scale of demand growth with a statistic (e.g. projected middle-class size) — mark schemes reward precise data over vague claims about 'increasing consumption'.
