How does a city become one of the wealthiest in the world? Let's consider New York City. NYC has held the title of the wealthiest city in the world for many decades now, housing around 59 billionaires and a whopping 345,600 millionaires! It is also home to Wall Street, the financial capital of the US and the world. The Big Apple has historically been a hub for trade and investment, due to a buzzing port and its very well connected location, with rivers and canal systems reaching out to the midwest. It checks all the boxes when it comes to being an economically successful place: physical connectedness (ports, rivers, public transporatation), investment opportunities (access to venture capital), and attracting a crowd of skilled individuals from around the globe, nurturing a culture of innovation. It takes decades of consistency for these factors turn a place around in terms of success and richness; a city can not accumulate wealth overnight, and if it does, this wealth will most likely not stick around for long. Most of the cities in our list have a similar history in terms of long-standing economical power (Tokyo, Paris, London), while others seem to have gained most of their wealth in the past 2 to 3 decades (San Francisco.)

　　In an attempt to rank the cities of the world according to wealth, we will use the Purchasing Power Parity (PPP) as a means of comparison. The PPP is a way to meaure prices in different countries (and ultimate convert between currencies), based on the equal amount of goods and services that can be bought. The PPP value of a city (or country) is commonly used by macroeconomic analysts and economists, as its a popular metric to determine a city's standard of living and economic prosperity.
