If there was a category above the ultra-wealthy, what would you name it? Maybe something like the “spaceship-owning-super-rich”? It's something to ponder as you peruse the latest list of the world's wealthiest people, released by Forbes earlier this week.

The report not only names the who's who of the billionaire club — all 1,826 of them — but also denotes different trends of wealth acquisition and distribution. For example, billionaires' aggregate net worth went up from $6.4 trillion in 2014 to $7.05 trillion this year. There are 46 billionaires under the age of 40, and of the 290 newly minted billionaires, 71 are from China. However, most of the ultra rich are from the United States or are first generation Americans.

How does Forbes compile this huge list? Their team of reporters gathers net worth, values individuals' assets such as stakes in public and private companies, real estate, yachts, art and cash, and take into account billionaire's estimated debt. They also reach out to billionaires to make sure their numbers are correct and, as their article says, “some cooperate; others don't.” Another important thing to note is that this Forbes list only ranks individuals rather than “multi-generational families who share large fortunes,” and so you will see that members of the same family are tied or outrank each other on the list.
