hello, this is the investigations team at More or Less. Please leave your statistical query after the tone and we'll investigate. Hello and welcome to More or less on the BBC World Service. I'm Ruth Alexander.
C
And I'm Charlotte MacDonald.
A
We recently dedicated a whole programme to answering a handful of questions from listeners around the world. This week's program is inspired by two questions from listeners in Africa.
C
One asks whether Nigeria really could be the biggest economy in Africa. The other wants to know, is Nigeria extremely poor? So is Nigeria rich poor or both? It's time we delved into the details.
D
My name is Odongo Pol and I'm from Kampala, Uganda. I saw a tweet which said Nigeria is about to overtake South Africa as Africa's biggest economy.
E
Would you please shed more light on
D
how they arrived at that?
A
So people have been saying for some time now that Nigeria is about to become Africa's biggest economy? Well, yes, now it has happened. The most widely recognized measure of the size of a country's economy is gdp, gross domestic product. And if you'd asked us at the beginning of April which economy was bigger, Nigeria or South Africa, we'd have said that Nigeria's GDP was about $260 billion and South Africa's 3,370 billion. So South Africa then was the biggest.
C
But recently, in the space of just one weekend, the size of Nigeria's economy almost doubled to $510 billion, making it much bigger than South Africa's.
A
So how did that happen? Well, Nigeria didn't have a huge growth spurt over a weekend. Instead, its National Bureau of Statistics carried out a major overhaul of how the country's GDP figures are calcul. The technical name for this is rebasing. And Rathia Khan, head of Africa Global Research at Standard Chartered bank, says it was about time it happened.
F
Nigerian GDP statistics had not been re based since 1990. Now, GDP statistics tend to be updated roughly every five years or so because price structures change, the composition of economies change. So essentially what we've seen from Nigeria is, is an attempt to introduce statistics that now take into account the growth that we've seen in sectors such as telecoms, such as Nollywood, and the broader entertainment industry in Nigeria.
C
Now, both these industries barely existed back in 1990, so until this week, they simply weren't being included in Nigeria's official GDP figures. But Razia Khan and others were surprised by the huge leap in the figure.
F
The consensus expectation amongst analysts was around the $400 billion mark. For GDP to have come out at $510 billion was really beyond even the top end of expectations.
A
So why is the new official GDP figure for Nigeria so much bigger than expected? It's because there were some big unknowns. Much of Nigeria's economic activity is informal and goes unrecorded. As Morten Y, author of Porn How We Are Misled by African Development Statistics and what to Do about it explains,
D
informal economy is not recorded. And for an economy like Nigeria, the informal sector is very, very important, particularly in sectors such as small time manufacturing, most of the construction sector, almost all of retail, wholesale and transporting sector. We're talking about operations that are done by businesses that are not registered, that are not delivering tax reports and that are only in few instances actually providing value added taxes and so forth. And therefore the Nigerian Bureau of Statistics has to resort to making qualified guesses, shortcuts and proxies.
A
Now Razia Khan says the Nigerian national statisticians did manage to survey more businesses than ever before to collect data. So although to some extent Nigeria's GDP is made up of educated guesswork, we have a much better idea of what's going on in the economy than we ever did before.
C
So Nigeria's GDP is almost double what we thought it was. But why does it matter? Morten Yervan Again with the new numbers,
D
then all these kinds of discussion resurface. Is it time to include Nigeria in the G20 group? Is now Nigeria? Should it be reclassified from a poor economy to a middle income country? Should Nigeria be not eligible for concessional lending from IMF and the World bank and so forth? But what we often forget to ask is, are these measurements meaningful? And as we just saw, when they changed the base year for GDP in Nigeria, then the GDP doubled. That means that we cannot and under no circumstance should we compare now the GDP of Nigeria with that of neighboring countries that might be operating on a completely different base here.
A
So Morten Yervin says you can't reliably compare country with country. There are too many differences and uncertainties in how GDP figures are calculated in each nation.
C
What's more, if you divide GDP by each person in the population, South Africans are much richer than Nigerians. So GDP on its own doesn't tell the whole story.
A
But of course Nigerians have been celebrating and feeling positive about their country's newly enhanced economic status. And you would, wouldn't you, if you just leapt up the world's economic rankings? But while they may be dream of joining the G20, the president of the World Bank, Jim Yong Kim, recently put Nigeria in a much less desirable club.
B
The fact is that 2/3 of the world's extreme poor are concentrated in just five India, China, Nigeria, Bangladesh and the Democratic Republic of Congo.
A
Did I hear right? Did the World bank just call Nigeria the biggest economy in Africa, an extremely poor country?
C
Yeah, well, sort of. And one of our listeners in Nigeria, Bundy Albert, got in touch to ask can that really be true? Are 2/3 of the world's poorest people in just five countries? And what proportion are in each? The World bank came up with a statistic to illustrate the problems with extreme poverty around the world.
A
But let's be clear. The World bank isn't saying that everyone in these five countries is extremely poor. Rather that they have a large number of people who are.
C
The figures it uses are based on data from household budget surveys carried out by national governments. And it says you're in extreme poverty if you live on less than $1.25 a.
A
Now this $1.25 a day measure has been criticised and that's something we've covered here on more or less before. And the World bank says itself that the quality of the surveys varies from country to country. But on the whole it does think the numbers are useful.
C
So of the 1.2 billion people in the world who are estimated to live on less than $1.25 a day, here's what proportion are in each of the five countries with the largest share. India 33% China 13% Nigeria 7% Bangladesh
A
6% Democratic Republic of Congo 5%. In Nigeria in particular, this hit a raw nerve. The Finance Minister was quick to point out that Nigeria's a middle income country which has a large number of poor people. And that's not unusual for developing countries. It's certainly not surprising that large developing countries with large populations have large numbers of poor people.
C
But an economist who writes for the Nigerian newspaper this Day, Waziri Adyo, says Nigeria mustn't be complacent.
E
The size of our GDP is bigger, exchange rate is stable, inflation rate is coming down. All those are very good. Fantastic. But how does that impact, you know, on people? What meaning does that have for somebody who doesn't have a job, who cannot feed himself or who cannot pay his bills? So that is what we need to see in Nigeria. We need to see this growth, translate to jobs, translate to reduce poverty, to reduce inequality. And we need to see the growth, you know, translate to things that will make life easier for people.
C
So is Nigeria a rich country or a poor country? Well, the numbers tell us it's both.

Podcast Summary: More or Less - "Nigeria: Rich or Poor?"
Date: April 12, 2014
Host: Ruth Alexander and Charlotte McDonald, BBC Radio 4
Main Theme:
The episode investigates the apparent paradox in Nigeria's economic status: following a change in GDP calculation, Nigeria suddenly became Africa's largest economy—yet it remains home to millions living in extreme poverty. The hosts delve into how GDP is calculated, the limitations of such statistics, and what these numbers really mean for the Nigerian people.

[07:46-08:58]
Conclusion:
The episode compellingly demonstrates that Nigeria's statistical promotion to Africa’s largest economy doesn’t mean most Nigerians are wealthy. GDP can leap through recalculations, but the reality of millions living on less than $1.25/day remains unchanged. The numbers, as the hosts suggest, show both richness and poverty—a reminder to look beyond headline statistics when judging a country’s wellbeing.
