What does it mean for a society to “develop”? The answer depends entirely on when – and where – you ask the question. After World War II, the word development became one of the most used and most contested terms in the social sciences. Over the following decades, scholars, policymakers, and international organisations continuously reshaped its meaning, pushing it far beyond its original, narrow focus on economic output. Today, development is understood as a multidimensional process involving economic growth, structural social change, and modernisation – three concepts that are deeply intertwined yet each carry their own weight and implications.

The post-WWII starting point: equating development with growth
The end of World War II created an urgent need for reconstruction and stability. In this environment, economic growth quickly became the dominant definition of development. The logic was straightforward: a country that produces more, earns more, and invests more is, by definition, developing. GDP became the single most important yardstick of national progress.
For the first two decades after the war – the 1950s and 60s – the concept of development was synonymous with modernisation, functioning as what scholars called the “Dominant Paradigm.” The reasoning was that if poor countries wanted to develop, they needed to replicate the economic and social structures of Western Europe and North America. Industrialisation was championed over agriculture, urbanisation was seen as a sign of progress, and decisions were made top-down by governments and expert planners.
The clearest policy expression of this growth-first thinking was the Marshall Plan, which channelled billions of dollars into rebuilding Western European economies after the war. Its perceived success reinforced the belief among Western policymakers that economic aid and capital injection could transform any society.
Rostow’s five stages: a blueprint for every nation
No theorist did more to formalise the growth model of development than Walt W. Rostow. In 1960, he published The Stages of Economic Growth: A Non-Communist Manifesto, which laid out a linear path that every society supposedly needed to follow.
Rostow’s model categorises economic growth into five distinct stages: the Traditional Society, Preconditions for Take-Off, Take-Off, Drive to Maturity, and the Age of High Mass Consumption. Each stage represents a specific set of social and economic characteristics, with industrialisation and mass consumption as the ultimate destination.
Rostow was not writing in a political vacuum. The book was published in 1960, at the height of the Cold War, and with the subtitle “A Non-Communist Manifesto,” it was overtly political. Rostow was fiercely anti-communist and modelled his theory after Western capitalist countries that had industrialised and urbanised. The theory was as much a geopolitical tool as an academic argument.
The US promoted modernisation theory to ensure that newly independent countries would join the capitalist free-market system rather than fall to communism – pouring money and aid into developing nations not purely out of charity, but to secure political allies.
The theory’s key assumptions
Modernisation theorists argued that modernisation is inevitable, irreversible, and that the transformation from traditional to modern societies will occur in a linear way. Change could be achieved through the diffusion of modern economic and political institutions, technology, and culture through foreign investment, aid, education, and mass media.
The central argument of modernisation theory is that developing countries need to follow the same path as the West in order to develop – adapting to Western cultures, values, and industrialising their economies, though requiring support from Western governments and companies to do so.
The strength of modernisation theory coincided with the establishment and growth of many key global institutions of development, such as the World Bank in Washington and the United Nations Economic Commission for Latin America in Santiago, which became strongly framed by core modernisation ideas – particularly the perception that industrialisation has a close relationship with development.
Development as social change: beyond the economic
As the decades progressed, the growth-centric model began to show its limits. GDP was rising in several developing countries through the 1960s and early 1970s – but poverty, inequality, and unemployment were rising alongside it. It became increasingly clear that economic numbers could mask deep social dysfunction.
In many countries in Latin America, Asia, and Africa, the GDP was indeed rising, but so was poverty, inequality, and unemployment. The “trickle-down” theory – the idea that if a country gets rich, money will eventually find its way to the poor – proved to be a myth. The rich were getting richer, elite groups were capturing the benefits of aid, and the rural poor were being displaced by dams and factories.
This realisation pushed sociologists and development economists to reconceptualise development as a process of social transformation – not just economic expansion. Development, in this broader framing, had to involve changes in social structures, power relations, access to education, healthcare, and the overall quality of life for ordinary people.
During a key phase in post-war development thinking, the emphasis shifted to “redistribution with growth.” The issues of concern became employment, policies for the direct alleviation of poverty, improving the distribution of income, and the satisfaction of basic human needs.
Dependency theory: a structural critique
The most powerful intellectual challenge to the growth-equals-development equation came from dependency theory, which emerged mainly from Latin American scholars in the late 1960s and 1970s. Rather than seeing underdevelopment as a starting point on a universal ladder, dependency theorists argued it was a condition actively produced by the global economic system.
Development and underdevelopment were understood not as autonomous, separate stages mapping onto the modern-tradition dualism of modernisation theory, but as structurally interrelated and co-produced by the emergence and spread of capitalism across the world. The periphery – the global South – was poor not because it was “backward,” but because it had been systematically impoverished through colonial extraction and ongoing unequal trade relationships.
Dependency theory rejected the view that underdeveloped countries are merely primitive versions of developed countries – arguing instead that they have unique features and structures of their own, and are the weaker members in a world market economy.
Modernisation: transformation of society’s structures and values
Alongside the economic debate, modernisation was also understood as a sociological process – one that reshapes institutions, values, and daily life. Modernisation theory examines the transition of societies from “traditional” to “modern” states, positing that this transformation is both inevitable and linear, drawing on various disciplines including economics, sociology, and political science to understand social change and its implications for development.
Weber’s approach later constituted the foundation for the paradigm of modernisation developed by Harvard sociologist Talcott Parsons. Parsons sought to develop an approach for poor nations to overcome what he thought impeded their development. He argued that traditional values – strong kinship ties, communal obligations, ritual practices – functioned as barriers to economic progress and needed to be replaced by modern, individualistic, and achievement-oriented values.
This framing had serious consequences. Post-development thinkers point out that assuming outside forces are needed to help a country develop negatively affects local practices, initiatives, and beliefs – a demeaning approach toward local populations. In many post-colonial societies, modernisation programmes eroded indigenous cultures and practices that had been framed as obstacles to progress, rather than as legitimate ways of organising social life.
Modernisation theory’s core problems
The theory has faced substantial criticism for being Eurocentric, overly deterministic, and for failing to account for external influences such as colonialism and global economic structures that contribute to inequality between nations. Critics argue that development does not follow a singular path and that traditional societies can have distinct trajectories shaped by their unique cultural heritages.
Critics have also noted that not all countries develop in such a linear fashion – some skip steps or take different paths. Rostow also assumes that all countries share a desire to develop in the same way, with the end goal of high mass consumption, disregarding the diversity of priorities that each society holds.
From growth to human development: the paradigm shift
The most significant reorientation in development thinking came in 1990, when the United Nations Development Programme introduced the Human Development Index (HDI). Developed under the intellectual leadership of economists Mahbub ul Haq and Amartya Sen, the HDI fundamentally challenged the idea that development could be reduced to income alone.
Despite decades of work on sustainable development, GDP still dominates development policy as a goalpost. While useful as a measure of economic activity, its use as a proxy for development can narrow what we aim to achieve, crowding out the social and environmental dimensions that underpin human wellbeing and sustain life.
The HDI combined three dimensions – health (life expectancy), education (years of schooling), and income (gross national income per capita) – into a single composite measure. This meant that a country with high GDP but poor healthcare and limited education could no longer claim to be “developed” in any meaningful sense.
For the first time, countries with similar income levels ranked very differently under the HDI. Some countries with high oil revenues found themselves ranked lower because they had not invested wealth into schools or hospitals – conversely, some countries with modest economies ranked surprisingly high because of excellent public health and education systems.
Sustainable development: integrating the environment
By the late 20th century, a third dimension entered the development conversation: environmental sustainability. The industrial model of the 1950s treated nature as an infinite resource to be exploited. By the 1980s, holes in the ozone layer, deforestation, and pollution made it clear that this path was dangerous – both for current populations and future generations.
The United Nations’ Sustainable Development Goals (SDGs), adopted in 2015, represent the most comprehensive contemporary attempt to integrate all three pillars of development. They link economic growth, social inclusion, and environmental protection into a single global framework – acknowledging that none of these dimensions can be pursued in isolation.
What development means in a contemporary context
The evolution of development thinking from post-WWII to today reflects a broader intellectual and moral maturation. The journey from GDP to HDI and beyond represents a shift from viewing humans as tools for economic production to viewing the economy as a tool for human flourishing.
Growth, change, and modernisation are not three separate theories – they are three lenses through which different eras have tried to answer the same question: what constitutes a better society? Economic growth remains essential; without material resources, social progress is constrained. But growth alone – as history has demonstrated – neither guarantees social equity nor human dignity. Social transformation that addresses structural inequalities, and modernisation that respects cultural diversity rather than erasing it, are equally indispensable components of any credible development agenda.
Development can no longer be credibly understood or measured without updating our understanding of what it means to be human – now inseparable from our relationships with the natural world, technology, and one another.
What do you think? If Rostow’s five stages were written today rather than in 1960, what new stage might need to be added to reflect the realities of climate change and digital inequality? And does framing development as “modernisation” still risk imposing one society’s values onto another – or has the concept evolved enough to avoid that trap?
