What Does Economic Growth Really Mean?

Economists usually start with a simple picture: the Production Possibility Frontier, or PPF, which shows the maximum amount a country can produce given its current resources and technology. When that frontier shifts outward, output has gone up. The traditional way of telling growth and development apart was almost mechanical. If output rose on its own, through the normal workings of a market economy, that was called economic growth, the kind usually associated with already developed economies. If the increase came through deliberate government action and structural reform, that was labeled economic development, more typical of the policy challenges developing economies face.

That distinction is a useful starting point, but it treats a rising GDP as the whole story, and over time economists have pushed back on that. The newer notion of growth treats a GDP increase as a means rather than an end. What actually matters is what that increase does to people's daily lives. A country can report growth of three or four percent one year and seven percent a few years later, and still leave its citizens feeling like their standard of living has gone backward. A high growth rate is necessary, but it is not sufficient. The real objective was always the quality of people's lives, and growth is only useful insofar as it gets us there.

Five kinds of growth worth refusing

Once quality of life becomes the actual goal, it becomes possible to describe growth that technically happened but still failed people. Development economists, following Mahbub ul Haq and the thinking that shaped the United Nations Human Development Programme, describe five patterns of growth that should be rejected even when the headline number looks good.

• Jobless growth. Growth that does not create enough jobs. A country should generally prefer a lower growth rate that creates more employment over a higher one that does not. This depends heavily on which sectors are expanding: labor intensive industries create far more jobs per unit of output than capital intensive ones such as steel or high technology manufacturing.
• Ruthless growth. Growth that widens the income gap rather than closing it, where most of the new income is captured by a small elite while the distribution across the rest of society stays unfair.
• Voiceless growth. Growth achieved without the participation of ordinary people in the decisions that shape it. A lower growth rate reached with genuine representation is preferable to a higher one imposed from above.
• Rootless growth. Growth pursued through a model that is poorly suited to a country's own culture, traditions, and social structure. A policy that worked well in one setting can fail elsewhere if it was never adapted to local conditions in the first place. Population and family planning policy is a commonly cited, and genuinely contested, example of this: models that reduced fertility rates in one cultural context have provoked serious ethical objections, including over coercion, when applied rigidly elsewhere. The lesson is less about any single policy and more about the general point, that growth strategies travel badly when they ignore local context.
• Futureless growth. Growth achieved in a way that cannot be sustained, most visibly in countries that lean heavily on a non renewable resource such as oil to drive GDP upward. The resource eventually runs out, and the generations that inherit the depleted asset, or a damaged environment, pay the price for a previous generation's growth.

That last point is really about sustainability, and it connects to one of the most widely used definitions in development economics, the one set out by the World Commission on Environment and Development in its 1987 report Our Common Future: development that meets the needs of the present without compromising the ability of future generations to meet their own needs. A country that grows today by depleting the resources or the environment that future citizens will depend on is not really developing, even if the GDP figures look strong in the meantime.

Put together, these five refusals are a useful checklist. Before accepting a growth number at face value, it is worth asking who got jobs from it, who captured the income, who had a say in it, whether it fits the society that produced it, and whether it can last.
