- The wealth of Africans is projected to grow by a third over the next decade
- The continent's wealth is agglomerating in a number of urban clusters, in the south, east and west
- Wealth is collected in a few other places - isolated capitals and mini-clusters stretching from Morocco down to Angola
Over the past decade, 19,000 Africans have become dollar millionaires. Africa's combined wealth has grown by 13% - 3% just in the last year alone. The combined individual wealth of all Africans is $2.3 trillion today – by the end of 2027, it will have increased by a third to $3.1 trillion. Clearly, it's boom time in Africa.
This map offers a revealing perspective on the wealth of the continent. The African subsoil may be resource-rich in many places, but as elsewhere in the world, it's in the great urban centres that money accumulates. And people too: by 2100, 13 of the world's 20 biggest megacities will be in Africa.

And this overview of Africa's richest cities, based on the The AfrAsia Bank Africa Wealth Report 2018, indicates where clusters of wealthy cities are developing across the continent, as well as showing a few more isolated locations of money aggregation.
- Long the most developed nation on the continent, South Africa – with four of Africa's ten richest cities – continues to be the economic engine of Africa's southern half. With a total GDP of $722 billion, South Africa as a whole continues to be the continent's wealthiest country, but on a per-capita basis it comes second after the tiny island nation of Mauritius ($32,700).
- The East African economy is dominated by a string of wealthy cities, from Uganda's capital Kampala via Nairobi and Mombasa in Kenya to Dar es Salaam, Tanzania's biggest city.
- In West Africa, a similar transnational conglomeration runs from Abidjan in Ivory Coast over Ghana's Accra to Lagos and Abidjan in Nigeria.
- In Morocco, Casablanca's wealth is flanked by that of Tangier and Marrakesh. In Egypt, Cairo dwarfs but not completely outshines Alexandria.
- The 'isolates', in descending order, are four capitals: Luanda (Angola), Addis Ababa (Ethiopia), Windhoek (Namibia) and Lusaka (Zambia).
Here are Africa's 10 wealthiest cities:
1. Johannesburg (South Africa): $276 billion

Fittingly, Africa's richest city was built on gold – on the Witwatersrand Gold Rush of 1886, to be exact. It's the commercial capital of South Africa and the wider region.
2. Cape Town (South Africa): $155 billion

The city with Africa's highest prime residential rates, at around $6,100 per square metre (similar to DC or Berlin) also is an important hub for financial services, retail and tourism.
3. Cairo (Egypt): $140 billion

Real estate, financial services and construction are some of the key sectors in this city of 9 million, the biggest metropolis in the Middle East.
4. Lagos (Nigeria): $108 billion

It may no longer be the country's capital, Lagos still is the gateway for 80% of Nigeria's exports – and the centre of the burgeoning film industry, a.k.a. Nollywood. At 21 million inhabitants (2016 est.), it's Africa's largest metropolis, as well as one of the world's fastest-growing cities.
5. Durban (South Africa): $55 billion

Subtropical Durban is South Africa's third-biggest city (after Johannesburg and Cape Town), second-biggest manufacturing hub and biggest port, as well as a major tourist destination. Durban's Gateway Theatre of Shopping is Africa's biggest mall. It has 12,000 parking slots, 390 stores, 90 restaurants, more than a dozen movie theatres (including an IMAX theatre), a skate park designed by Tony Hawk, and the highest fountain in Africa.
6. Nairobi (Kenya): $54 billion

Kenya's capital and largest city (metro area: 7 million) Nairobi is also known as the Green City in the Sun. Founded in 1899 by the British as a rail depot, the city today is home to thousands of Kenyan businesses, as well as the Nairobi Securities Exchange, Africa's 4th-largest stock exchange; and regional hub for hundreds of multinationals.
7. Luanda (Angola): $49 billion

Luanda is the biggest city, major port and capital of Angola – and its metro area is home to one in three Angolans. While the majority of Luandans live in poverty, the booming oil and gas industry has created huge wealth for a minority (as well as a boom in banking and building). Luanda is one of the world's most expensive cities for ex-pats, in part because of high import tariffs imposed to help pay for diversifying the economy.
8. Pretoria (South Africa): $48 billion

The administrative capital of South Africa and the hub of the wider Tshwane metro area, Pretoria is also a centre for academia and R&D, as well as commerce and industry, including metalworks to car factories.
9. Casablanca (Morocco): $42 billion

Officially ad-Dar al-Bayda in Arabic but informally known as Kaza, Casablanca is the largest city in the entire Maghreb region (metro area: 7 million), and its economic hub. It is important both as port city and financial centre. Major Moroccan and multinational companies are headquartered here rather than in the political capital Rabat.
10. Accra (Ghana): $38 billion

A merger of coastal settlements around British, Dutch and Danish coastal forts, Accra in 1957 became the capital of sub-Saharan Africa's first independent nation. Today, it is a centre for manufacturing, marketing, finance, insurance, and transportation.
Over the next decade, the AfrAsia Bank's report expects growth to remain strong in South Africa, Angola, Morocco, Egypt, Ivory Coast, Tanzania and Nigeria – not coincidentally countries hosting many of the hubs shown on this map.
But the strongest growth projections apply to some of the smaller countries in Africa: Uganda, Rwanda, Ghana and Mauritius.

Arches of chaos in space manifolds.
Humanity could be making its way through the Solar System much faster thanks to the discovery of a new superhighway network among space manifolds. Don't get your engines roaring along this "celestial autobahn" just yet, but the researchers believe the new pathways can eventually be used by spacecraft to get to the outer reaches of our Solar System with relative haste.
The celestial highway could get comets and asteroids from Jupiter to Neptune in less than a decade. Compare that to hundreds of thousands or even millions of years it might ordinarily take for space objects to traverse the Solar System. In a century of travel along the new routes, a 100 astronomical units could be covered, project the scientists. For reference, an astronomical unit is the average distance from the Earth to the Sun or about 93 million miles.
The international research team included Nataša Todorović, Di Wu, and Aaron Rosengren from the Belgrade Astronomical Observatory in Serbia, the University of Arizona, and UC San Diego. Their new paper proposes a dynamic route, going along connected series of arches within so-called space manifolds. These structures, coming into existence from gravitational effects between the Sun and the planets, stretch from the asteroid belt to past Uranus.
The most pronounced of these structures are linked to Jupiter by its strong gravitational pull, explained UC San Diego's press release. They influence the comets around the gas giant as well as smaller space objects called "centaurs," with are like asteroids in size but exhibit the composition of comets.

"Space manifolds act as the boundaries of dynamical channels enabling fast transportation into the inner- and outermost reaches of the Solar System," write the researchers. "Besides being an important element in spacecraft navigation and mission design, these manifolds can also explain the apparent erratic nature of comets and their eventual demise."

The researchers discovered the structures by analyzing collected numerical data on the millions of orbits in the Solar System. The scientists figured out how these orbits were contained within known space manifolds. To detect the presences and structure of the space manifolds, the team employed the fast Lyapunov indicator (FLI), used to detect chaos. The scientists ran simulations to compute how the trajectories of particles approaching different planets like Jupiter, Uranus and Neptune would be affected by possible collisions and the manifolds.
While the results are encouraging, the next step is to figure out how these arches can be used by spacecraft for much speedier travel. It's also not clear how similar manifolds work near Earth. Also unclear is how they impact our planet's run-ins with asteroids and meteorites or any of the man-made objects floating up in space near us.

How Apple and Nike have branded your brain | Your Brain on Money | Big Think youtu.be
Brands can manipulate our brains in surprisingly profound ways. They can change how we conceptualize ourselves and how we broadcast our identities out to the social world. They can make us feel emotions that have nothing to do with the functions of their products. And they can even sort us into tribes.
To grasp the power of brands, look to Apple. In the 1990s, the company was struggling to compete with Microsoft over the personal computer market. Despite flirting with bankruptcy in the mid-1990s, Apple turned itself around to eventually become the most valuable company in the world.
That early-stage success wasn't due to superior products.
"People talk about technology, but Apple was a marketing company," John Sculley, a former Apple marketing executive, told The Guardian in 1997. "It was the marketing company of the decade."
So, how exactly does branding make people willing to wait hours in line to buy a $1,000 smartphone, or pay exorbitant prices for a pair of sneakers?
Branding and the brain
For more than a century, brands have capitalized on the fact that effective marketing is much more than simply touting the merits of a product. Some ads have nothing to do with the product at all. In 1871, for example, Pearl Tobacco started advertising their cigarettes through branded posters and trading cards that featured exposed women, a trend that continues to this day.
It's crude, sure. But research shows that it's also remarkably effective, even on monkeys. Why? The answer seems to center on how our brains pay special attention to information from the social world.
"In theory, ads that associate sex or status with specific brands or products activate the brain mechanisms that prioritize social information, and turning on this switch may bias us toward the product," wrote neuroscience professor Michael Platt for Scientific American.
Brands can burrow themselves deep into our subconscious. Through ad campaigns, brands can form a web of associations and memories in our brains. When these connections are robust and positive, it can change our behavior, nudging us to make "no-brainer" purchases when we encounter the brand at the store.

It's a marketing principle that's related to the work of Daniel Kahneman, a psychologist and economist who won the 2002 Nobel Memorial Prize in Economic Sciences. In his book "Thinking Fast and Slow", Kahneman separates thinking into two broad categories, or systems:
- System 1 is fast and automatic, requiring little effort or voluntary control.
- System 2 is slow and requires subjective deliberation and logic.
Brands that tap into "system 1" are likely to dominate the competition. After all, it's far easier for us as consumers to automatically reach for a familiar brand than it is to analyze all of the available information and make an informed choice. Still, the most successful brands can have an even deeper impact on our psychology, one that causes us to conceptualize them as something like a family member.
A peculiar relationship with brands
Apple has one of the most loyal customer bases in the world, with its brand loyalty hitting an all-time high earlier this year, according to a SellCell survey of more than 5,000 U.S.-based smartphone users.
Qualitatively, how does that loyalty compare to Samsung users? To find out, Platt and his team conducted a study in which functional magnetic resonance imaging scanned the brains of Samsung and Apple users as they viewed positive, negative, and neutral news about each company. The results revealed stark differences between the two groups, as Platt wrote in "The Leader's Brain":
"Apple users showed empathy for their own brand: The reward-related areas of the brain were activated by good news about Apple, and the pain and negative feeling parts of the brain were activated by bad news. They were neutral about any kind of Samsung news. This is exactly what we see when people empathize with other people—particularly their family and friends—but don't feel the joy and pain of people they don't know."
Meanwhile, Samsung users didn't show any significant pain- or pleasure-related brain activity when they saw good or bad news about the company.
"Interestingly, though, the pain areas were activated by good news about Apple, and the reward areas were activated by bad news about the rival company—some serious schadenfreude, or "reverse empathy," Platt wrote.
The results suggest a fundamental difference between the brands: Apple has formed strong emotional and social connections with consumers, Samsung has not.
Brands and the self
Does having a strong connection with a brand justify paying higher prices for their products? Maybe. You could have a strong connection with Apple or Nike and simultaneously think the quality of their products justifies the price.
But beyond product quality lies identity. People have long used objects and clothing to express themselves and signal their affiliation with groups. From prehistoric seashell jewelry to Air Jordans, the things people wear and associate with signal a lot of information about how they conceptualize themselves.
Since the 1950s, researchers have examined the relationship between self-image and brand preferences. This body of research has generally found that consumers tend to prefer brands whose products fit well with their self-image, a concept known as self-image congruity.
By choosing brands that don't disrupt their self-image, consumers are able not only to express themselves personally, but also broadcast a specific version of themselves into the social world. That might sound self-involved. But on the other hand, humans are social creatures who use information from the social world to make decisions, so it's virtually impossible for us not to make inferences about people based on how they present themselves.
Americus Reed II, a marketing professor at the University of Pennsylvania, told Big Think:
"When I make choices about different brands, I'm choosing to create an identity. When I put that shirt on, when I put that shirt on — those jeans, that hat — someone is going to form an impression about what I'm about. So, if I'm choosing Nike over Under Armour, I'm choosing a kind of different way to express affiliation with sport. The Nike thing is about performance. The Under Armour thing is about the underdog. I have to choose which of these different conceptual pathways is most consistent with where I am in my life."
Making smarter decisions
Brands may have some power over us when we're facing a purchasing decision. So, considering brands aren't going away, what can we do to make better choices? The best strategy might be to slow down and try to avoid making "automatic" purchasing decisions that are characteristic of Kahneman's fast "system 1" mode of thinking.
"I think it's important to always pause and think a little bit about, "Okay, why am I buying this product?" Platt said.
As for getting out of the brand game altogether? Good luck.
"I've heard lots of people push back and say, "I'm not into brands,"" Reed II said. "I take a very different view. In some senses, they're not doing anything different than what someone who affiliates with a brand is doing. They have a brand. It's just an anti-brand brand."
