Economic growth means an economy produces more than before. It is a quantitative idea, shown as numbers. Gross Domestic Product (GDP) is the value of goods and services made inside a country in a year. If GDP rises over time, the economy is growing. Growth can be measured in tonnes of food, kilometres of road, or money value of output. It is a number that goes up or down. When output falls, economists call it 'negative growth'.

Sustainable development means growing the economy without harming future generations. It means improving lives today without stopping future people from doing the same. The Brundtland Report of 1987 gave the most used definition. It says development must meet present needs. But it must not stop future generations from meeting their own needs.

The demographic dividend is extra growth from a young workforce. It happens when working-age people outnumber dependants. Working age usually means ages 15 to 59, or 15 to 64. Non-working age means children and old people. They depend on others for support. More workers compared to dependants means more saving. It also means more output, so growth speeds up. This works only if these workers find good jobs.

Education and health are not ordinary market goods. They give benefits beyond the person who gets them. For example, an educated worker helps co-workers learn too. A healthy person does not spread disease to others. Economists call such goods merit goods. A merit good is something society wants for everyone to have. Markets under-supply merit goods because poor families cannot pay the full price. This is why governments invest in education and health. This spending builds human capital, not just welfare.
