Nigeria Applies Advanced Geospatial Technology For Census Preparation

Published

on

For the First Time in Its History, the Country Plans to Use Digital Tools to Prepare an Accurate Population Count

Based on 2006 census data, the United Nations (UN) estimates that 224 million people now live in Nigeria. According to this estimate, Nigeria is Africa’s third-most populous country and the sixth-most populous country in the world. The UN predicts that by 2050, Nigeria will be the third-most populous country in the world, behind only China and India.

Having a more accurate count of how many Nigerians there are—and a better understanding of where they live—is critical for many reasons, including implementing health and education plans and discovering where housing may be in short supply. However, it’s been nearly 18 years since Nigeria conducted an official census..

In 2006, Nigeria’s census information was collected and recorded on paper. Now, Nigeria is preparing for its first digital census. Nigeria’s National Population Commission (NPC), which conducts the census, has embraced GIS technology—in particular, ArcGIS Online, ArcGIS Pro, and ArcGIS Enterprise—as it prepares to create a digital record of the country’s population and housing. The census will be essential for eventually determining where to invest the country’s resources and provide services to the people who live there.

Former Nigerian president Muhammadu Buhari has said that the country’s inability to conduct a census since 2006 had created an “information vacuum,” as the data had become out-of-date. Originally scheduled to take place in March 2023—less than a month after a presidential election—the census has been postponed twice as the country continues to wait (as of press time) for its new president to declare when it will be conducted.

USING GIS FOR AN ACCURATE COUNT

In the meantime, the NPC has spent years preparing, including conducting a trial census to test its operations. Its mission is focused on accurate and reliable data collection and analysis. That’s why the NPC turned to cutting-edge technology, said Foluke Yetunde Adebayo, coordinating director for the NPC’s GIS and data quality management.

“We developed a suite of customized geoprocessing tools designed to streamline and enhance critical aspects of our data management processes,” she said. The tools address several key functions in the NPC’s data management workflow, including data cleaning, editing, boundary delineation, geocoding, and data validation.

The NPC based the foundation of its mapping work on the Global Statistical Geospatial Framework, established by the UN.

“A fundamental aspect of this approach is the assignment of precise geospatial attributes to all new entities or records of persons, households, and buildings that are collected from the field,” Adebayo said. “These attributes are assigned based on the geographical location of the entities, enabling a robust geospatial dimension in the database.”

The NPC began introducing GIS into its census preparations in 2014 using ArcGIS technology. High-resolution satellite imagery was used to identify features on the ground, including buildings, roads, railways, water bodies, and boundaries of villages and towns. The identified features were then geocoded, resulting in a countrywide basemap. The basemap was then used to create enumeration areas, the geographic areas that census takers canvass.

TECHNOLOGY PLAYS A CRITICAL ROLE IN PREPARATIONS

ArcGIS Online serves as a central repository for the NPC’s large dataset, which includes millions of building records and the enumeration area frame. During an end-to-end test conducted in preparation for the census, ArcGIS Online also allowed for about 600,000 devices in the field to access the server simultaneously without any glitches or downtime, Adebayo said. This enabled workers to access and update data seamlessly, a critical aspect of a successful census operation.

The NPC’s GIS analysis team used ArcGIS Pro—and ArcPy in particular—to clean the dataset, identify and correct spatial topology errors, create thematic maps, and geocode.

In ArcGIS Enterprise, the commission used ArcGIS Server, ArcGIS Data Store, and ArcGIS Enterprise portal for tests and the trial census. So far, ArcGIS Enterprise has managed the results of field data collection, including household listing datasets. The NPC has also used ArcGIS Enterprise to create census dashboards for data visualization within a secure organizational environment. Eventually, ArcGIS Enterprise will play a vital role in managing and visualizing the resultant census data, Adebayo said.

Once the census is underway, the data collected by field enumerators will be cross-referenced with initial mapping data. This comparison helps identify any significant changes or discrepancies between the two datasets. The validation process will be automated using custom scripts in ArcGIS Enterprise. The scripts are designed to evaluate whether the observed level of change in the data falls within the expected range or if it exceeds the predetermined threshold, which prompts further review.

The commission plans to use a hybrid census mapping methodology to count people living in remote locations and areas of conflict. Aided by high-resolution satellite imagery and neighborhood analysis theory, the NPC demarcated all conflict areas that may be inaccessible. If the areas ultimately can’t be accessed by enumerators during the census, the NPC plans to estimate populations by using modeling techniques developed by spatial data solutions company GRID3.

LOOKING BEYOND THE CENSUS

Using the maps created for the census, the Nigerian Postal Service is developing a modern, digital postal code system. The NPC created custom tools in ArcGIS Pro to apply a set of well-defined rules and a coding system to meet the unique requirements of the project. “Its core function is to delineate the entire country into postcode areas, each of which was restricted to a size not exceeding two hectares [nearly five acres] and limited to containing no more than 99 postcode units,” Adebayo said.

In the future, the commission hopes to use geospatial artificial intelligence tools to assist in updating maps, processes, and estimates. “This will significantly enhance the accuracy, efficiency, and automation of geospatial data management and reduce the resources required to update the data,” Adebayo said.

The NPC also expects to develop more GIS tools and models for analysis. It won a Special Achievement in GIS Award at the 2022 Esri User Conference for its use of GIS technology in preparing for the census. By basing the census on a well-planned geospatial platform, the country will be able to standardize its procedures and more easily extract critical demographic data.

Presidency Refutes Afenifere’s Deceitful Statement on President Bola Tinubu’s Midterm:

Published

on

Chief Sunday Dare

The statement from a factional Afenifere group raises serious concerns about a penchant and deliberate attempt to find faults and trade in deceit instead of objectivity. The group has found it challenging to accept that under the Renewed Hope Agenda of President Bola Tinubu, Nigeria’s comeback story is firmly underway.

The rebellious Afenifere claims that President Bola Tinubu’s administration’s performance over the past two years has witnessed a regression in human development, economic mismanagement, and democratic backsliding.

This is a jaundiced view, echoing the view of opposition politicians, one of whom the group supported in the 2023 election.

A balanced assessment based on available data reveals a more objective and progressive picture, with significant achievements amid the challenges expected from a country like Nigeria with decades-old problems.

Beyond its confounding conclusions based on prejudice, the statement raises the following issues. With the ensuing point-by-point clarification, it will become clear that the group’s position is neither grounded in facts nor logic.

  1. Economic Reforms and Their Impact

The factional Afenifere’s claim that Tinubu’s economic reforms, particularly the removal of fuel subsidy and the floating of the naira, have led to “unmitigated sufferings” and “economic deforms” seeks to draw attention to some of the challenges but overlooks the macroeconomic gains. The removal of the fuel subsidy, announced on May 29, 2023, saved the government over $10 billion in 2023 alone, reducing fiscal strain and redirecting funds to other sectors. Unifying the foreign exchange market and the naira’s floatation aimed to address distortions in the currency market, boosted foreign reserves to $38.1 billion by 2024 and achieved a trade surplus of N18.86 trillion for the country.

Under the Tinubu administration, Nigeria’s annual inflation rate fell to 23.71% in April 2025 from 24.23% in the prior month. Food inflation, the most significant component of the inflation basket, remained elevated but moderated to 21.26% from 21.79%

While these figures indicate stabilisation, the immediate impact on ordinary Nigerians is not lost. The government’s cash transfer programme, which provides funds to the poorest households and benefits over 5.7 million households, is a credible outreach.

However, dismissing the twin policies as “unforced errors” ignores the unsustainable nature of the previous subsidy regime and multiple exchange rate systems, which were draining public finances. A more balanced critique would acknowledge the necessity of reform while emphasising the need for better-targeted social safety nets.

As of today, the Tinubu administration has recorded over 900,000 beneficiaries of the Presidential Loan and Grant Scheme, over 600,000 beneficiaries of the Students’ Loan Scheme, NELFUND, N70,000 minimum wage, NYSC monthly stipend increase from N33,000 to N77,000, Free CNG kits distributed to thousands of commercial drivers across Nigeria with CNG buses rolled out in partnership with state governments, leading to a significant drop in transport costs. The administration also recorded over $10 Billion FX debt cleared, Federal account allocation to states growing by 60%, enabling more local development projects, N50 billion released to end the perennial ASUU strikes, and over 1,000 PHCs revitalised nationwide with an additional 5,500 undergoing upgrades.

The administration also disbursed N75 Billion in palliative funds to states and LGs for food distribution and cash transfers, over 150,000 youths are being trained in software development, tech support and data analysis under the 3 Million Technical Talent (3MTT) project, over 20,000 affordable housing units under construction under the renewed Hope cities program launched across Nigeria, N200 Billion in Loans to farmers and agro-processors. Other gains: over two million Nigerians are now connected to new digital infrastructure and community broadband hubs and public WiFi projects, 3.84% GDP growth in Q4 2024 (highest in 3 years), over $50 Billion in new FDI Commitments, Net Foreign Exchange Reserves up from $3.99 Billion (2023) to $23.11 Billion (2024), over $8 Billion in new oil and gas investments unlocked, and over $800 million realised in processing investments in solid minerals in 2024 and inflation as at April was down to 23.17%.

It is now pertinent to inquire from opposition leaders about alternative strategies they would propose in contrast to this administration’s extensive list of significant achievements currently benefiting Nigerians in real-time.

  1. Cost of Governance and the Oronsaye Report

The assertion that the Tinubu administration has failed to implement the Oronsaye Report and instead increased governance costs is inaccurate. The Oronsaye Report, which recommends the merger or scrapping of government agencies to reduce expenditure, has not been fully implemented and has drawn criticisms; it must be noted, however, that the administration has made some efforts to improve fiscal discipline. The fiscal deficit was reduced from 5.4% of GDP in 2023 to 3.0% in 2024, and the debt service-to-revenue ratio dropped from nearly 100% in 2022 to under 40% by 2024. The government also recorded over N6 trillion in revenue in Q1 2025, partly due to removing Ways & Means financing and fuel subsidies. These steps demonstrate fiscal prudence and will eventually translate into immediate, tangible relief for citizens. The administration is working earnestly to address these optics and prioritise cost-cutting measures, including implementing the Oronsaye Report, to restore public trust.

  1. Allegations of Prebendalism and Corruption

Afenifere’s claim that the administration favours “the privileged and connected” through corrupt palliative distribution and mega-project allocations is questionable. Reports of palliatives being mismanaged or distributed through unverified channels have no doubt surfaced, raising concerns about transparency.

The administration has taken steps against corruption, such as suspending Humanitarian Affairs Minister Betta Edu in January 2024 over alleged fund diversion, signalling some commitment to accountability. Critics may argue that more systemic action is needed, but dismissing all the efforts as propaganda overlooks these initial steps.

Without abusing Presidential powers, the administration is working on expediting action on all pending investigations and prosecution of corrupt practices. At the same time, critical agencies are collating credible evidence on ongoing corruption litigations. It must, however, be noted that in 2024, the Economic and Financial Crimes Commission (EFCC) secured a record-breaking 4,111 convictions, marking its most successful year since its inception. They recovered over N364 billion and significant amounts in foreign currencies, including $214.5 Million, $54,318.64, and 31,265 Euros.

The EFCC achieved its single most significant asset recovery in 2025, with the final forfeiture of an Abuja estate measuring 150,500 square meters and containing 725 units of duplexes and other apartments. The EFCC concluded the final forfeiture and handed the estate to the Ministry of Housing in May 2025.

  1. Democratic Concerns and Centralisation

Afenifere’s accusation that the Tinubu administration is pursuing a “one-party state totalitarianism” and undermining democratic institutions is unsupported and lacks merit. The claim of neutralising the legislature and judiciary is also a false alarm.

The public should note that the Supreme Court has upheld opposition victories in states like Kano, Plateau, and Abia, suggesting judicial independence. The Independent National Electoral Commission (INEC) has faced criticism for allegedly appointing individuals said to be ruling party affiliates, but no evidence confirms these appointees are card-carrying APC members.

The allegation that the Tinubu government cracks down on peaceful protesters is primarily unfounded. It is a regurgitated rhetoric deployed under previous administrations as a reflection of broader challenges in Nigeria’s democratic culture.

The issue of the State Police is more complex than the oversimplified approach of the factional Afenifere’s statement. Every administration policy is subject to security impact assessment before implementation, and there is a difference between the State Police being widely advocated and a Police State that critics may blame the Federal Government for if implemented without caution.

  1. Security and Social Welfare

Contrary to the impression created, the administration’s security record is impressive. Over 13,500 terrorists, bandits, and insurgents have been neutralised and 7,000 arrested in the past year, though there is still some news of abductions and violent attacks. The administration’s proactive response to security-related matters has paved the way for more farmers to return to their farms, impacting food production and supply.

The administration also embarked on agricultural initiatives, including tractor procurement, fertiliser distribution, and increased mechanisation.

The government has also not relented on its Regional Development drive as the administration succeeded in establishing Development Commissions across 6 Geopolitical zones (South West, North West, North Central. North East, South East and the Niger Delta) to empower communities and accelerate developments.

  1. Political Climate and 2027 Elections
    The claims of government-sponsored conflicts within opposition parties lack concrete evidence and should be ignored.

Economic reforms are undoubtedly laying the foundation for long-term stability, with GDP growth at 4.6% in Q4 2024 and a Fitch B credit rating upgrade as evidence. Moody’s Investors Service’s latest upgrade of Nigeria’s rating from Caa1 to B3, with a Stable Outlook, indicates that the Tinubu administration is on the right path.

The government is not oblivious to some discontent and difficult times among Nigerians. There is an urgency to deliver more tangible results, which is guaranteed given the impressive performance of the administration in just two years.

Afenifere’s statement saw the cup as half empty. On the contrary, it’s half full. Under President Tinubu’s administration, some of Nigeria’s hydra-headed problems are being tackled headlong.

The administration has achieved fiscal improvements, such as reduced deficits and increased revenues, which will eventually translate into meaningful microeconomic relief for most Nigerians in the short term, even as the government moves to address these issues with greater empathy and transparency.

The administration’s demonstrable priorities are securing the nation, fixing the economy, and improving human capital development.

Responsible citizens and political leaders must work collaboratively with the administration to address the challenges and counter disinformation, as highlighted in the admonition against fake news and deceptive AI videos.

Under President Tinubu’s leadership, Nigeria is turning the corner. From stabilising the naira and curbing inflation to reducing debt burdens and

expanding access to education and health, the administration delivers bold reforms with actual results. With improved security, regional inclusion, anti-corruption measures, and institutional rebuilding, Nigeria’s comeback story is not yet complete — but it is firmly underway.
