Countries differ in economic development because their ability to produce income and improve health, education and living standards depends on several connected factors. Each factor can be both a cause and a consequence, creating reinforcing development paths.
| Difference | Main causal connection to development | Important qualification |
|---|---|---|
| income | higher real income increases consumption and tax revenue, allowing more spending on health, education and infrastructure | an average may hide poverty or unequal distribution |
| productivity | more output per worker raises productive capacity, wages, profits and competitiveness | productivity depends on skills, health, capital and technology |
| population growth | slower growth can reduce pressure on services and raise resources per head; a growing working-age population can expand labour and markets | the effect depends on dependency, jobs and whether output grows faster than population |
| primary, secondary and tertiary sectors | secondary and tertiary activity often adds more value, pays more and is less weather-dependent than subsistence primary work | productive resource extraction can earn jobs and exports; overdependence brings price and depletion risks |
| saving and investment | saving can finance capital, infrastructure, education and technology → productivity and future income rise | very low income can restrict saving; investment must be productive and accessible |
| education | skills and qualifications improve employability, occupational mobility, productivity and earning power | quality, access, time lags and skilled emigration affect the gain |
| healthcare | healthier workers have fewer absences and can work and learn more productively; life expectancy and wellbeing rise | effective provision depends on income, access, staff and spending quality |
| natural resources | usable resources can supply inputs, exports, tax revenue and investment funds | resources do not guarantee development if prices fluctuate, ownership is narrow, governance is weak or stocks are depleted |
A positive chain may run: education and healthcare → higher productivity → higher income → more saving, tax revenue and investment → better capital and services → still higher productivity. The reverse can create a low-development cycle.
Do not classify a country from one indicator. A large primary sector or rapid population growth may constrain development in one setting and support it in another; use the full causal context and living-standard outcomes.
