What GDP rebasing will tell us about Nigeria today, By Ajumah Glory

In the engine room of any thriving nation, data is the fuel. Without accurate statistics, a country cannot honestly know itself, let alone grow. For Nigeria, the move to rebase its Gross Domestic Product (GDP) is more than a technical exercise; it is a crucial moment of recalibration, an opportunity to realign economic perception with current reality. It is a necessary, credible, and long-overdue move that will help reposition national planning and policy on a more reliable foundation.

For most people, GDP may sound like a term best left to economists. However, it plays a decisive role in determining how our lives unfold. The Gross Domestic Product is the value of everything we produce within our borders. goods and services, large and small. It serves as the national thermometer, gauging whether the economy is expanding or shrinking, and it is what governments, investors, and international bodies rely on to make decisions. When it rises, it suggests growth; when it dips, it signals trouble.

However, it is essential to note that GDP growth does not automatically equate to development. A country may record impressive GDP figures while large portions of its population remain poor, unemployed, or underserved. Development involves more than just output; it is about improving lives, ensuring equity, and protecting the environment. GDP can only tell part of the story, and even then, only if it is correctly measured.

This is why Nigeria’s decision to update its GDP base year is so vital. The base year serves as the benchmark for comparing economic activity over time. Nigeria has until now been using 2010 as its reference point. However, economies are not static. They evolve. New industries emerge, technology transforms the way people live and work, and consumer behaviour shifts dramatically. What mattered in 2010 may have changed entirely by 2024. Continuing to measure today’s economy with outdated tools would be like using a decade-old map to navigate a rapidly growing city; you are bound to miss your way.

Rebasing is the process of updating the base year. In Nigeria’s case, the new base year selected is 2019, a year deemed stable and data-rich, and crucially, just before the COVID-19 pandemic distorted global economies. By resetting the benchmark to 2019, Nigeria can better capture the current economic realities. The digital economy, tech startups, gig work, entertainment, and other modern sectors that were barely registered a decade ago now significantly feature in the national output. Their contributions must be properly counted.

The last time Nigeria undertook this exercise was in 2014, which revealed that the economy was significantly larger than previously thought, pushing Nigeria to the top of Africa’s economic rankings. This was not because people suddenly started producing more overnight, but because the lens through which we measured economic activity had become more precise and more accurate. This time, the rebasing will similarly offer a fresh perspective, one that incorporates previously uncounted sectors, better estimates sectoral contributions, and gives the government clearer direction on where to invest and intervene.

So, why hasn’t Nigeria rebased its GDP more frequently, as recommended by the United Nations Statistical Commission, which advises that countries update their GDP base year every five years? The answer lies in the sheer cost and complexity of the process. Rebasing is not just about changing numbers; it requires nationwide surveys, censuses, data collection, and rigorous statistical modelling. Instruments like the Nigeria Living Standards Survey, agricultural census, and enterprise data must all be updated. These require time, technical expertise, and, most significantly, funding, often in short supply.

Despite these challenges, the benefits of rebasing far outweigh the costs. A more accurate GDP framework gives policymakers the tools to target problem areas with precision. It reveals where jobs are being created, where productivity is lagging, and where government policy can make the most significant impact. For investors and international partners, a clearer picture of the economy enhances confidence and credibility. For citizens, it offers hope that policy will be better informed and more responsive to actual needs.

The data from the rebasing will almost certainly show shifts in Nigeria’s economic structure. Some sectors will be revealed as bigger and more influential than previously recorded. Others may shrink in relative importance. However, such revelations are not a cause for alarm. They are a welcome sign that our economy is being seen in its true light, not through outdated shadows.

Ultimately, GDP rebasing is about more than statistics. It is about vision, about a country willing to look in the mirror and measure itself honestly. It is about taking stock, correcting assumptions, and planning for a future grounded in facts. Nigeria’s rebased GDP will not solve all its economic problems, but it provides a sharper, more precise map with which to chart its course. Moreover, in a world where evidence-based policy is the gold standard, that clarity is priceless. Even for the layperson, the message is clear: a more accurately measured economy is a better understood economy, and a better understood economy is far more likely to deliver the prosperity Nigerians deserve.

The rebasing of Nigeria’s Gross Domestic Product is more than an exercise in statistical refinement; it is a bold declaration of intent. It signals that Nigeria is ready to confront its economic realities with clarity and precision, shedding outdated assumptions in favour of data that reflects today’s complexities. This recalibration offers a fresh opportunity for the government to pursue targeted interventions, for investors to make informed decisions, and for citizens to engage more confidently with conversations about national growth and development.

However, the actual test of this rebasing lies not in the numbers themselves, but in how we use them. The updated GDP figures must serve as a catalyst for more innovative policymaking, improved governance, and inclusive progress. Suppose Nigeria can sustain a culture of regular economic reflection through timely data and evidence-based planning. In that case, it will not only reposition itself on the global economic map but also chart a more purposeful and prosperous course for future generations.
