In 300 B.C., Carthage was one of the world’s largest cities with up to 700,000 people living within its walls. The Carthaginian republic was a force to be reckoned with, controlling inconceivable amounts of wealth and land all around the Mediterranean.
However, just over a century later in 146 B.C., Carthage was burnt to the ground by the Romans. The destruction of Carthage was so thorough that many things are still not known about their civilization today. Carthage went from being a major power to literally being wiped off of the map.
A few decades after the annihilation of Carthage, it was Rome’s turn to become the world’s largest city for close to 500 years. Of course, Rome itself would fall by 476 A.D. for a variety of reasons.
And so the title of the world’s largest city would transfer again, this time to Constantinople across the Mediterranean.
The World’s Largest Cities Throughout History
In the grand scheme of history, things change quite fast. One cataclysmic choice or event can turn even the greatest empire into a heap of rubble. Sometimes the decline of a world-class city is more gradual – and it is over time that it loses its title to another place in a far and distant land.
The following animated map from KPMG Demographics tracks the world’s largest cities from 4,000 BC to today, and it shows how temporary a city’s rise to prominence can be.
(Keep in mind that there is some disagreement by historians over which cities were the biggest in certain time periods.)
The power of industrialization and technology can be seen here. Up until the 1800s, it was almost unfathomable to have a city of more than a million inhabitants.
Sanitation was a major limiting factor, but other issues like transportation and a lack of density also made it a challenge. The Industrial Revolution changed that, and starting in the 1800s you see cities like London, New York, and Tokyo taking the title in an exponential fashion. It caps off with Delhi in 2050, expected to have a whopping 40 million inhabitants by that time.
However, it’s worth seeing this urban growth through a different lens. Instead of looking at the biggest cities overall, the below map from Max Galka’s Metrocosm blog looks at the founding of major cities to show the progress of urbanization from 3700 B.C. until today.
You can use the sliding bar to adjust the date. The real fireworks begin in the year 1200, with an explosion in cities between 1800 and today.
Here’s one final look at cities and their modern populations, this time an interactive 3d globe also from Metrocosm:
This gives an idea of where the largest concentrations of people live today. The globe also puts into perspective a small subsection of Asia, which holds more of the world’s population within a small circle than outside of it.
Ranked: The Best and Worst Pension Plans, by Country
As the global population ages, pension reform is more important than ever. Here’s a breakdown of how key countries rank in terms of pension plans.
Ranked: Countries with the Best and Worst Pension Plans
The global population is aging—by 2050, one in six people will be over the age of 65.
As our aging population nears retirement and gets closer to cashing in their pensions, countries need to ensure their pension systems can withstand the extra strain.
This graphic uses data from the Melbourne Mercer Global Pension Index (MMGPI) to showcase which countries are best equipped to support their older citizens, and which ones aren’t.
Each country’s pension system has been shaped by its own economic and historical context. This makes it difficult to draw precise comparisons between countries—yet there are certain universal elements that typically lead to adequate and stable support for older citizens.
MMGPI organized these universal elements into three sub-indexes:
- Adequacy: The base-level of income, as well as the design of a region’s private pension system.
- Sustainability: The state pension age, the level of advanced funding from government, and the level of government debt.
- Integrity: Regulations and governance put in place to protect plan members.
These three measures were used to rank the pension system of 37 different countries, representing over 63% of the world’s population.
Here’s how each country ranked:
The Importance of Sustainability
While all three sub-indexes are important to consider when ranking a country’s pension system, sustainability is particularly significant in the modern context. This is because our global population is increasingly skewing older, meaning an influx of people will soon be cashing in their retirement funds. As a consequence, countries need to ensure their pension systems are sustainable over the long-term.
There are several factors that affect a pension system’s sustainability, including a region’s private pension system, the state pension age, and the balance between workers and retirees.
The country with the most sustainable pension system is Denmark. Not only does the country have a strong basic pension plan—it also has a mandatory occupational scheme, which means employers are obligated by law to provide pension plans for their employees.
Adequacy versus Sustainability
Several countries scored high on adequacy but ranked low when it came to sustainability. Here’s a comparison of both measures, and how each country scored:
Ireland took first place for adequacy, but scored relatively low on the sustainability front at 27th place. This can be partly explained by Ireland’s low level of occupational coverage. The country also has a rapidly aging population, which skews the ratio of workers to retirees. By 2050, Ireland’s worker to retiree ratio is estimated to go from 5:1 to 2:1.
Similar to Ireland, Spain ranks high in adequacy but places extremely low in sustainability.
There are several possible explanations for this—while occupational pension schemes exist, they are optional and participation is low. Spain also has a low fertility rate, which means their worker-to-retiree ratio is expected to decrease.
Steps Towards a Better System
All countries have room for improvement—even the highest-ranking ones. Some general recommendations from MMGPI on how to build a better pension system include:
- Increasing the age of retirement: Helps maintain a more balanced worker-to-retiree ratio.
- Enforcing mandatory occupational schemes: Makes employers obligated to provide pension plans for their employees.
- Limiting access to benefits: Prevents people from dipping into their savings preemptively, thus preserving funds until retirement.
- Establishing strong pension assets to fund future liabilities: Ideally, these assets are more than 100% of a country’s GDP.
Pension systems across the globe are under an increasing amount of pressure. It’s time for countries to take a hard look at their pension systems to make sure they’re ready to support their aging population.
Animated Map: The History of U.S. Counties
This video highlights the history of American counties, and how their boundaries have changed over the last 300 years.
Animated Video: The History of U.S Counties
Did you know that there are 3,142 different counties in the U.S. today?
Going as far back as the 1600s, English settlers arriving in the New World envisioned counties as a means of accessible government—a county seat was meant to be within a day’s buggy ride for every citizen.
While the role of counties in local government has remained significant in modern times, their boundaries have changed drastically over the years.
This animated map by Alexander Varlamov visualizes the history of U.S. county borders, and how these jurisdictions have evolved over time.
Before diving in, it’s important to note a few county-equivalents that function similarly but go by different names:
- Boroughs/Census areas: Alaska is made up of 19 boroughs, but the majority of its landmass is not included in them. Rather, it’s officially labeled by the Alaskan government as the unorganized borough.
- Parishes: Instead of counties, Louisiana uses the term parishes because of its French and Catholic heritage.
- Independent cities: These are cities that operate outside their surrounding county’s jurisdiction. There are 41 independent cities in the U.S. and 38 of them are in Virginia.
Over 300 Years of Growth
The number of counties in the U.S. has increased dramatically since the early days of American history. Here’s a look at their growth since 1790:
|Year||Number of Counties and Parishes|
The first county was established in 1634, over 100 years before the first Census was taken (and long before America gained independence). It was created in James City, Virginia—an interesting location, considering Virginia now has the highest concentration of independent cities.
Why does Virginia have so many independent cities? The state’s separation of counties and cities dates back to the early 1700s. With a rural population and low productivity, it was difficult to establish town centers. After several attempts, the General Assembly gave up. Independent cities were established instead.
Counties as a political organization have been around for hundreds of years, but some individual counties haven’t lasted long.
For instance, Bullfrog County in Nevada was established in 1987 and dissolved just two years later. During its brief existence, it had no population and no infrastructure—and its primary purpose was simply to prevent Yucca Mountain from becoming a nuclear waste dump.
While Bullfrog County has since been dissolved, the controversy around the nuclear waste site is ongoing as of 2020.
The latest official county, Broomfield Country, was established in Colorado in 2001.
Although it’s been decades since the last county was created, there have been continual boundary changes and status updates—sometimes for political reasons. For instance, the Supreme Court recently ruled that half of Oklahoma is within a Native American reservation. While this doesn’t necessarily change ownership, it does affect jurisdiction and county authority.
Though the lines on the map are more or less static now, the invisible lines of county jurisdiction will continue to change and evolve over time.
