Band 8 model answer

The shift of large populations from rural to urban areas has been one of the defining trends of the modern era. Although this movement brings genuine hardship, I believe it is on balance a positive development, both for the individuals involved and for broader economic progress.

The case for urban migration is rooted in opportunity. Cities concentrate jobs, healthcare, education and infrastructure in ways that dispersed rural communities simply cannot replicate. A farmer's child who moves to Nairobi, Jakarta or Mumbai gains access to schools, hospitals and a far wider range of livelihoods than would ever be available in a remote village. Historically, urbanisation has accompanied nearly every episode of sustained economic growth, from nineteenth-century Britain to twenty-first-century China, where hundreds of millions lifted themselves out of poverty by migrating to manufacturing cities.

The costs, however, cannot be dismissed. Rural depopulation can devastate agricultural communities, leaving ageing populations to maintain farms with dwindling labour. At the same time, rapid urban growth overwhelms city infrastructure, producing overcrowded slums, polluted air and inadequate sanitation for the poorest arrivals. These problems are real and demand policy attention.

Yet they are better understood as management challenges than as arguments against urbanisation itself. Governments that invest in affordable housing, public transport and basic services can accommodate urban growth sustainably, as shown by Curitiba in Brazil and Medellín in Colombia, where smart city planning transformed previously chaotic growth into functional, liveable urban environments.

In conclusion, while the rural exodus creates pressures at both ends of the migration journey, the expanded opportunities it gives individuals and the economic dynamism it generates for nations lead me to view it as a fundamentally positive development when properly managed.
