Map: Which Cities Hold Africa’s Wealth?

Mapping Africa’s Wealth

The Chart of the Week is a weekly Visual Capitalist feature on Fridays.

The economy in Africa is on the rise, and financial hubs are beginning to emerge.

While the resource-rich African continent has seen only 13% growth in total private wealth over the past 10 years, the 3% spike in the past year alone indicates the growth is just warming up. Africa will also be home to 13 out of the 20 of the world’s largest megacities by 2100.

In this week’s chart, we take a look at Africa’s wealthiest cities, courtesy of this recent 2018 report from New World Wealth and AfrAsia Bank.

Africa’s Evolving Economy

While Africa has traditionally played a minor role in the world market, the continent is coming into its own as a hub for financial services and entrepreneurship.

Africa’s growing elite has added 19,000 millionaires over the past decade, with total private wealth totaling $2.3 trillion. These figures are predicted to increase by 34% over the next decade, reaching $3.1 trillion by the end of 2027.

The five wealthiest cities hail from three countries:

1. Johannesburg, South Africa ($276 billion)
Founded in the Witwatersrand Gold Rush of 1886, South Africa’s City of Gold is a hub for financial services, professional services (law firms and consultancies), construction, telecommunications, and basic materials.

2. Cape Town, South Africa ($155 billion)
One of South Africa’s three capital cities, Cape Town’s major sectors include real estate, financial services, retail, and tourism. Cape Town has the highest prime residential rates on the continent at US$6,100 per square meter, similar to cities such as Washington, D.C., or Berlin.

3. Cairo, Egypt ($140 billion)
A hub for Africa and the Middle East, Cairo’s major sectors include real estate, construction, financial services, and basic materials.

4. Lagos, Nigeria ($108 billion)
The clearing house for 80% of Nigeria’s imports, major sectors include basic materials, real estate, construction, telecommunications, transport, and financial services.

5. Durban, South Africa ($55 billion)
Home to the biggest shopping center in Africa – complete with 350 stores, 70 restaurants, 18 movie theaters, an IMAX theater, an indoor climbing wall, and a skate park designed by Tony Hawk – Durban’s major sectors include real estate, finance, healthcare, construction, retail, and transport.

At Risk: The Geography of America’s Senior Population

The U.S. senior population is much more vulnerable to COVID-19. Which states and cities have the most people in this at-risk age group?

U.S. Senior Population

At Risk: The U.S. Senior Population

The U.S. now has the largest number of confirmed COVID-19 cases globally, and modelling predicts that the country could see about 100,000 to 200,000 total deaths. Unfortunately, adults aged 65 or older—about 16% of the U.S. population—are at much higher risk of both severe illness and death.

Today’s chart uses U.S. Census Bureau data to map the percentage of the population that is 65 years or older by state. It also outlines the urban areas that are most heavily skewed towards this older age group.

Proportion of Seniors by State

Below is the full breakdown of the U.S. senior population by state, using the latest available data from 2018.

Maine tops the list with 20.6% of its population comprising adults age 65 or older. At the other end of the scale, Utah’s seniors make up only 11.1% of its population.

Notably, Florida has the second highest percentage and number of seniors nationwide. Its governor just announced the state’s stay-at-home order on April 1st, after taking criticism for refusing to do so earlier.

New York, the current global hot spot of COVID-19, is close to the national average with 16.4% of its population aged 65 or older. However, with over 3.2 million seniors, the sheer volume of individuals needing hospitalization has already put a strain on the state’s healthcare system. Governor Andrew Cuomo says the state will run out of its current supply of ventilators in less than a week.

The Most Vulnerable Urban Areas

On a local level, which places have the highest proportion of seniors? Based on all urban areas* with a population of 250,000 or more, here’s how the top 50 looks:

*Urban areas consist of a downtown core and adjacent territories

With 6 areas in the top 10, Florida is quite vulnerable at the local level as well. Other states with multiple areas on the list include Ohio, Pennsylvania, and New York.

The Senior Population of Current U.S. Hotspots

To determine the vulnerability of current COVID-19 hotspots, we compared U.S. counties with a high number of cases per capita against their percentage of seniors.

Counties at the bottom left have low readings on both metrics. Conversely, counties in the top right have a dangerous combination: a high concentration of cases and vulnerable seniors.

senior population vs covid-19 outbreak

Multiple counties in New York occupy the top right quadrant, with Yonkers being the worst off. Los Angeles county, which has a similar population to all counties in New York City, has fewer cases and a smaller proportion of seniors.

To date, outbreaks have been mostly focused in urban areas where populations tend to be younger. However, as COVID-19 begins infiltrating rural areas, healthcare systems will need to contend with both older age groups and fewer resources.

Global Shutdown: Visualizing Commuter Activity in the World’s Cities

Amid the COVID-19 crisis, cities are dramatically slowing down. Today’s chart demonstrates the impact of lockdowns on commuter activity worldwide.

Published

Staying Put: The COVID-19 Commuter Decline

Every day, millions of people worldwide rely on public transport networks to get around. But in times of crisis, bustling cities with high volumes of commuter traffic can come to a dramatic halt.

Today’s chart breaks down daily data from Citymapper’s Mobility Index, according to trips planned on the transport app across 41 select cities.

The results paint a unique picture of how social distancing and lockdown measures are impacting commuter and economic activity in major urban hubs.

Cities With the Biggest Drops in Activity

As the government response to the COVID-19 pandemic intensifies and people are urged to stay home, transit activity is dropping everywhere.

However, some areas are seeing more of a reduction in activity than others. Where has activity declined the most over the month?

RankCityCountry04-Mar11-Mar18-Mar25-MarTotal Change (%)
#1Vienna🇦🇹 Austria128%92%9%6%-122%
#2Lisbon🇵🇹 Portugal128%108%24%12%-116%

#9Los Angeles🇺🇸 USA108%81%23%13%-95%
#10Melbourne🇦🇺 Australia113%110%53%20%-93%

*Note: Data measures the % of city moving compared to 100% baseline.

Overall, Vienna and Lisbon are the cities with the biggest average drop in commuter activity over the past few weeks. This decline in mobility is correlated with a spike in the proportion of COVID-19 cases in the population:

  • Austria
    March 4: 2.6 per million
    March 25: 586 per million
  • Portugal
    March 4: 0.4 per million
    March 25: 232 per million

That said, not every city is seeing a precipitous decline in activity — let’s look at those next.

Standing Still, or On Guard

Cities that saw lower decreases in commuter activity over recent weeks can generally be slotted into three categories:

  1. Cities that were already on or near shutdown (Seoul, Milan)
  2. Cities that have so far avoided major impacts from the virus (St. Petersburg)
  3. Cities that successfully mitigated spread (Singapore)

Here are the 10 cities on the list that saw the lowest changes in activity:

RankCityCountry04-Mar11-Mar18-Mar25-MarTotal Change (%)

#10Lyon🇫🇷 France75%97%6%4%-71%

*Note: Data measures the % of city moving compared to 100% baseline.

St. Petersburg is still seeing commuter activity at 69% of normal levels as of March 25th, as the proportion of confirmed COVID-19 cases in Russia remains low, at roughly 3.4 per million.

Milan has the lowest activity of any city at 3%, and has been in shutdown for most of the month.

Although Singapore’s total COVID-19 cases grew from 18.8 to 95.4 per million, it still has 62% commuter activity. Interestingly, Singapore is one of the few countries that has been able to properly control and manage its COVID-19 outbreak.

Biggest Weekly Declines

As the month progressed, various cities showed stark one-week declines in commuter activity based on official healthcare recommendations and growing case numbers.

After a government lockdown announced on March 9, Rome experienced the sharpest decline of -75% commuter activity in the week from March 4 to March 11. Currently, there is only 5% activity compared to usual, similar to Milan.

In the second week of March, COVID-19 cases in France jumped fourfold, from 27.3 per million to 118.4 per million people. As a result, Lyon saw a whopping -91% drop in commuter activity—going from 97% on March 11 to 6% on March 18.

Over the past week, as cases in Australia reached 95 per million, Sydney and Melbourne exhibited the highest average declines at -36% and -33% in commuter activity respectively.

The COVID-19 pandemic is affecting everything from the stock market to the environment. With cities actively working to keep populations in isolation and healthy during this time, it may take a while before commuter activity returns to normal.
