Rostow's Stages of Economic Growth
Rostow's model says every country develops through the same five stages, from traditional society to mass consumption, driven by a key leading sector that triggers takeoff into self-sustaining growth.
Walt Rostow published this model in 1960, arguing that development is a ladder every country climbs in the same order. Stage one is traditional society: subsistence farming, little trade, no formal industry. Stage two, preconditions for takeoff, brings early infrastructure, commercial agriculture, and outside investment or ideas that start loosening the old traditional economy. Stage three is takeoff itself, the short, sharp stage where growth becomes normal rather than exceptional. Stage four is the drive to maturity, where industry diversifies beyond that original sector and spreads through the whole economy. Stage five is mass consumption, where people buy goods well beyond basic needs and services dominate.
Takeoff depends on a leading sector: one industry that grows fast, attracts investment, and pulls related industries along with it. Textiles did this for Britain, steel and rail did it for the United States. The leading sector creates jobs, demand for raw materials, and profits that get reinvested elsewhere in the economy, so growth stops depending on one spark and starts feeding itself.
The model sits in Unit 7 next to Wallerstein's core-periphery model, which pushes back hard on Rostow's assumption that every country climbs alone. Wallerstein argues periphery countries stay poor partly because core countries benefit from that arrangement, through trade terms, resource extraction, and dependency, not just because they haven't hit takeoff yet. Rostow also struggles with resource-exported growth: a country that gets rich selling one commodity, like oil, can look like it is in takeoff without ever building the diversified industry that stage four requires, leaving it exposed if that one export collapses.
Key terms
- Takeoff
- The stage where growth becomes self-sustaining instead of occasional, usually within 20 to 30 years.
- Leading sector
- The single fast-growing industry that pulls investment and jobs into the rest of the economy during takeoff.
- Drive to maturity
- The stage where industry diversifies beyond the original leading sector and spreads through the economy.
- Core-periphery model
- Wallerstein's alternative theory that wealthy core countries benefit from unequal trade with poorer periphery countries.
Watch it explained
- How it worksWalk me through Rostow's five stages from traditional society to mass consumption.
- How it worksHow does the takeoff stage need one leading sector to pull the whole economy along?
- Worked exampleShow me where South Korea, Brazil, and Chad sit on Rostow's stages today.
- Common mistakeWhy isn't Rostow's model able to explain countries that never take off at all?
- Going furtherWhat happens to Rostow's ladder when a country's growth comes from one exported resource?
