Where are the top destinations for millionaires and billionaires worldwide?

Today, the richest cities in the world are finance and tech hubs, drawing affluent residents to thriving metropolitans. Given the flow of wealth and high demand for prime property, it’s no surprise that these cities have some of the most exclusive residential markets globally.

The above graphic shows the world’s wealthiest cities by the number of millionaires and billionaires, based on data from Henley & Partners annual World’s Wealthiest Cities Report.

Cities with the Most Millionaires and Billionaires

Below, we order the richest cities globally, based on their millionaire population in 2023 (net worth of $1 million USD or more) along with each city’s billionaire population (net worth of $1 billion USD or more):

With 340,000 millionaires and 58 billionaires, New York City stands as the world’s wealthiest metropolitan area.

Between 2012 and 2022, the number of high net worth individuals living in the Big Apple increased by 40%, even as the pandemic drove an exodus of wealthy people from the city. Overall, the wealth of New York City’s residents is roughly $3 trillion, more than the GDP of Canada.

Falling in second is Tokyo, boasting a millionaire population of 290,300 residents. Roughly a fifth of the country’s millionaires live in the city.

With one of the fastest growing millionaire populations across this list, The Bay Area ranks in third. Driven by

Wildfires have become a summer specter in North America, looming on the horizon as parts of the country warm and dry out.

We chart the total wildfire area burned in 2023 in the U.S., categorized by state, based on figures from the National Interagency Coordination Center.

Which U.S. States Saw the Most Area Burned by Wildfires?

Wildfires in California and Alaska together account for one-fourth of all land burned in the U.S. in 2023. Both states saw wildfire damage to more than 300,000 acres.

Zooming out, nearly half of the 2.7 million acres affected by wildfires in 2023 were concentrated in only five states.

Due to hot, dry summers, Western states in particular see more wildfires. The New York Times notes that the American West has a Mediterranean climate where precipitation is concentrated around winter months. Thus the region’s hottest and driest months coincide.

A complex interplay of factors are leading to North America’s long wildfire season: increasing summer temperatures, erratic precipitation patterns, changing land use, and ironically, fire suppression practices.

But what does the data say? We visualize the millions of acres burned by U.S. wildfires from 1983 to May 2024, per statistics from the National Interagency Fire Center.

2010 and 2015 Saw Record Land Burned by Wildfires

From glancing at the chart, it’s apparent that U.S. wildfires are burning significantly more acres on average in the 2010s than they did in the 1980s. Interestingly, the World Economic Forum points out that while the number of fires itself has fallen since 2005, the land burned has increased, indicating wildfire intensity has grown.

In 2015, wildfires burned more than 10 million acres in the country, a first since these records began. Five years later saw a repeat, thanks to four Californian fires that together burned more than 2.3 million acres in the state.

For comparison, U.S. wildfires burned approximately 2.7 million acres in total in 2023, the lowest amount recorded since 1998. An unusually wet Californian summer helped

According to the World Health Organization, air pollution is responsible for 7 million deaths annually, and could cost the global economy between $18–25 trillion by 2060 in annual welfare costs, or roughly 4–6% of world GDP.

And with predictions that 7 in 10 people will make their homes in urban centers by mid-century, cities are fast becoming one of the frontlines in the global effort to clear the air.

In this visualization, we use 2024 data from the State of the Air report from the American Lung Association to show the most polluted cities in the United States.

What is Air Pollution?

Air pollution is a complex mixture of gases, particles, and liquid droplets and can have a variety of sources, including wildfires and cookstoves in rural areas, and road dust and diesel exhaust in cities. 

There are a few kinds of air pollution that are especially bad for human health, including ozone and carbon monoxide, but here we’re concerned with fine particulate matter that is smaller than 2.5 microns, or PM2.5 for short. 

The reason for the focus is because at that small size, particulate matter can penetrate the bloodstream and cause all manner of havoc, including cardiovascular disease, lung cancer, and chronic pulmonary disease. 

The American Lung Association has set an annual average guideline of 9 µg/m³ for PM2.5, however, the World Health Organization has set a much more stringent limit of 5 µg/m³.

The 21 Worst Polluted Cities in the U.S.

Here are the top 21 most polluted cities in the U.S., according to their annual average PM2.5 concentrations:

Over 80% of the American population lives in an “urban area” according to the U.S. Census Bureau. But where are all of the country’s largest cities, and what patterns can we see from their state locations?

This map shows U.S. states by their number of incorporated areas (i.e. cities or towns) that have more than 250,000 residents. Data for this map comes from 2024 estimates made by World Population Review, which were based on the latest U.S. Census Bureau figures.

California and Texas—also the most populous U.S. states—each have more than 10 cities with at least a quarter of a million inhabitants.
