Economic growth: how do we measure it, and why does it matter?

Economic growth is a measure of how well a country is doing. When the economy grows, production, earnings and investment also grow. This has an impact on jobs, wages and public finances. Here you can read about what economic growth means, it is measured and what factors play a role.

What do we mean by economic growth?

A country’s economy grows when it adds more value through the production of goods and services during a given period than it did previously. This refers to the value adjusted for inflation, or the volume. We usually measure this growth on an annual basis and express it as a percentage.

Why is economic growth important?

Economic growth tends to lead to the creation of new jobs and higher incomes. The government collects more tax revenues and can spend more, for example on healthcare, education or defence. If growth stalls, jobs, public finances and investment will come under pressure.

What determines economic growth?

The most important measure is GDP (gross domestic product): the total value of everything a country produces in a year. If GDP rises, the economy is growing. If GDP falls, the economy is contracting. GDP provides an indication of the size of the economy, but says less about overall prosperity, inequality or the environment.

GDP can also be measured by adding up all of a country’s expenditures. This includes exports and investment and consumption by businesses, households and the government:

Foreign trade

The Netherlands has an open economy and many Dutch companies make their money abroad. Strong exports mean increased production, jobs and tax revenue. World trade and international uncertainty, such as trade tensions, therefore have a direct impact on our economic growth.

Investment

Investments in machinery and technology can boost productivity and encourage innovation. The economy then grows. When companies invest less – for example, due to uncertainty or high costs – innovation stagnates and growth slows down. The government also makes investments, for instance in new roads.

Consumption

Household consumption is a key driver of the economy. When people spend more, demand for goods and services rises. Companies then sell more. In times of uncertainty or a decline in purchasing power, the opposite happens. Government spending such as on healthcare is also regarded as consumption. If that spending rises, economic growth will increase.

Interrelated factors

Economic growth influences – and is influenced by – various interrelated factors:

Inflation

Economic growth affects prices. If demand for goods and services increases, inflation may rise. The prices of goods then rise more sharply, purchasing power falls and costs for businesses increase. This holds back consumption and investment. This is why central banks aim for an inflation rate of around 2%. At that rate, consumers continue to spend money and businesses are willing to invest. The economy continues to grow steadily.

We distinguish between nominal growth (including inflation) and real growth (excluding inflation).

Housing market

Developments in the housing market are linked to household consumption. Rising house prices can boost consumption, as homeowners feel more prosperous. At the same time, high house prices make homes less affordable for first-time buyers, which limits their financial scope for spending. Households also tend to become cautious with their money when house prices fall.

Labour market

The more people work, the more money they earn and spend. Both high unemployment and labour shortages can hamper growth. Productivity matters too: working more efficiently can drive growth without people having to work longer hours.

Public finances

Government spending stimulates the economy, which in turn boosts demand for goods, services and labour. If supply cannot keep pace, inflation may go up. Sound public finances ensure stability and give households and businesses a sense of confidence, which is positive for growth.

Our projections

Our economists monitor key economic developments and publish economic forecasts for the short and medium term. We publish these projections at various times throughout the year. 

You can find our most recent projections here

How do we prepare our projections?

We publish the spring and autumn projections in June and December. These are our official forecasts for the Dutch economy, covering the current year and the next two years. 
We use various tools to prepare our projections, including the DELFI economic model. We also use this model to assess the consequences of changes in economic policy or economic conditions. You can also check this yourself. You can find out, for example, what the consequences might be of higher energy prices or higher wages: Link to the DELFI model.

For short-term projections, we use:

  • the DFROG nowcasting model to estimate current developments in the Dutch economy.
  • the DNB business cycle indicator, which helps to identify transition points that signal a change in the economic cycle at an early stage.
