In San Francisco, you really might be living next door to a billionaire.

While New York may have more billionaires total, the city boasts more per capita than any other city in the world including Dubai and Hong Kong.

With a booming tech industry in a city of less than a million, San Francisco has one billionaire for approximately every 11,600 residents, according to a new report from Wealth-X.

The research company's annual "Billionaire Census" takes a close look at the world's billionaire population, and the 2018 numbers and analysis reveals that while the global billionaire class is slumping, North America saw a modest 3-percent increase in its billionaire population.

The number of billionaires worldwide declined by 5.4 percent to 2,604 individuals and the report says everything from Brexit to global trade tensions are to blame.

Here are three more interesting facts related to billionaires in San Francisco from the report:

1) San Francisco has the third-highest number of billionaires total with 75. New York comes in No. 1 with 105 and Hong Kong at No. 2 with 87.

2) In the past decade San Francisco has seen huge jumps in its billionaire population but 2018 was less impressive. The city added one billionaire to its total from 2017 to 2018. The report says, "Although 2018 was a less auspicious year for tech stocks, amid slower demand and a modest push-back from the public and governments to the actions of certain high-profile firms, wealth creation was still supported by broadly favorable economic conditions in the US and the continuing growth of digitalization around the world."

3) San Francisco is the clear leader when it comes to billionaire density. New York, Dubai and Hong Kong follow in 2nd to 4th place respectively, with about one billionaire per 80,000-85,000 inhabitants.

The report doesn't name specific billionaires but a recent survey from Forbes did, and revealed four Bay Area billionaires made the top-50 ranking of the world's richest people, including Zuckerberg (net worth $62.3 billion), Oracle founder Larry Ellison ($62.5 billion) and Google co-founders Larry Page ($50.8 billion) and Sergey Brin ($49.8 billion).
