Measuring What Matters

Why consistent measurement is essential to guide investment, policy and innovation in the Space Economy

The space economy is becoming more important to everyday life. Satellite systems support communications, navigation, weather forecasting, environmental monitoring, national security, agriculture and global supply chains. Yet the economic structure behind these services remains difficult to observe as a single, connected system.

Launches, investment announcements and satellite deployments provide valuable information, but none of them alone can explain whether the space economy is becoming stronger, more productive or more sustainable.

To understand its development, the space economy needs consistent measurement.

The first challenge is definition

Before an economy can be measured, its boundaries must be defined.

The OECD describes the space economy broadly, covering the public and private activities that create value through the exploration, understanding and use of space. This includes launch vehicles and satellites, but also ground infrastructure, navigation equipment, telecommunications, meteorological services, research and space-enabled applications.

The United States Bureau of Economic Analysis uses a related statistical definition covering goods and services that are used in space, directly support space activity, require input from space to function or contribute to the study of space.

Both definitions reveal an important reality: the space economy extends far beyond rockets and spacecraft. Its economic value is distributed across manufacturing, communications, research, software, data services, construction, defence and many other industries.

Without a clear definition, estimates may include different activities and produce very different results. These differences do not necessarily mean that one estimate is incorrect. They often mean that institutions are measuring different parts of the same expanding system.

Consistency makes change visible

A single figure provides a snapshot. A consistent series reveals direction.

When definitions, sources and calculation methods remain stable, changes across time become more meaningful. Researchers can distinguish sustained development from temporary activity, while investors and policymakers can evaluate whether growth is broad or concentrated.

The importance of methodology is demonstrated by the BEA’s 2023 estimates. Under its standard definition, real GDP generated by the United States space economy grew by 0.6%. Under a narrower definition that excluded direct-to-home satellite television, satellite radio and educational services, real growth reached 2%.

Both calculations used valid data. The difference came from the boundaries of measurement.

This illustrates why economic indicators must disclose what they include, how they are calculated and when their methods change. Without that transparency, apparently comparable figures may describe different economic realities.

Measurement guides investment

Investment decisions depend on an understanding of demand, risk and the ability of a market to generate durable value.

Raw investment totals can show how much capital entered the sector, but they cannot show whether that capital was distributed across multiple industries or concentrated in a few large transactions. Launch totals may indicate operational activity, but they can be dominated by a single constellation. Revenue growth may appear strong in current prices while being much weaker after inflation is considered.

Reliable measurement helps investors examine the structure beneath headline figures:

• Which segments are generating recurring revenue?

• Where is demand becoming commercially sustainable?

• How dependent is growth on government procurement?

• Is investment creating diversified capacity or increasing concentration?

• Which parts of the supply chain face bottlenecks?

• Are expanding activities creating measurable economic value?

The BEA estimated that the U.S. space economy contributed $142.5 billion to GDP in 2023, generated $240.9 billion in gross output and supported approximately 373,000 private-sector jobs. Statistics of this kind give decision-makers more than a market-size estimate: they show how space activity connects to production, employment and the wider economy.

Measurement improves policy

Governments influence the space economy through research funding, procurement, regulation, infrastructure and international cooperation. Effective policy therefore depends on understanding where public intervention is necessary and what results it produces.

Consistent indicators can help policymakers assess whether public programmes are developing domestic capability, attracting private investment, supporting employment or improving access to critical services.

They can also reveal structural risks. Increasing launch activity may create economic opportunity while placing additional pressure on orbital capacity. Expanding defence demand may support commercial providers while increasing dependence on public contracts. A growing number of satellites may improve connectivity while intensifying debris and coordination risks.

Good measurement does not remove these trade-offs. It makes them visible.

Comparable international statistics are especially important because space activity operates across borders. ESA, Eurostat, the OECD, the European Commission’s Joint Research Centre and the U.S. BEA have worked on shared statistical classifications to improve the consistency of space-economy measurement between countries.

However, continuity remains a challenge. In March 2026, the BEA announced that it would no longer regularly produce its U.S. space-economy statistics. Existing data remain valuable, but the decision demonstrates how difficult it can be to maintain specialized economic measurement over time.

Measurement supports innovation

Innovation is often associated with technological breakthroughs, but measurement is what allows their economic effects to be evaluated.

A new launch system may reduce costs. A satellite constellation may improve connectivity. An Earth-observation platform may provide faster environmental intelligence. An in-orbit servicing technology may extend spacecraft life.

The innovation becomes economically meaningful when its effects can be measured through lower costs, wider adoption, greater reliability, new revenue, improved productivity or reduced risk.

Measurement also helps identify areas where innovation is still needed. Data may expose supply-chain constraints, infrastructure shortages, skills gaps, excessive market concentration or rising sustainability costs. These signals can guide research and capital toward problems with real economic significance.

No single indicator is enough

The space economy cannot be understood through one metric.

Market size explains scale, but not necessarily momentum. Launches show activity, but not the distribution of value. Investment reflects capital formation, but not commercial success. Research indicates future capacity, but its economic impact may take years to appear.

A more complete view requires several indicators to be considered together and over time.

This is the principle behind Etemion’s approach to the Space Economy Index. SEI is not intended to replace national accounts or calculate the absolute size of the industry. It is being developed to observe shorter-term direction and momentum through a consistent framework covering investment, launch activity, research and competition.

The objective is not to reduce the entire space economy to a perfect number. It is to create a structured reference point that can be tested, improved and interpreted transparently.

From information to understanding

The space economy already produces enormous amounts of information. The greater challenge is organizing that information into a form that supports understanding.

Consistent measurement creates a common reference for researchers, investors, companies and policymakers. It makes developments comparable, reveals patterns that individual events cannot and allows assumptions to be evaluated against evidence.

Every mature economy develops systems for understanding itself. As the space economy becomes larger, more connected and more consequential, its measurement infrastructure must develop with it.

Because better participation begins with better decisions—and better decisions begin with measuring what matters.
