World Billionaires (2026)
A 2026 snapshot of the world's billionaires — name, net worth, industry, and citizenship. Great for rankings, group-bys, and skeptical questions about wealth data.
One row per billionaire: name, estimated net worth, source of wealth, industry, and country of citizenship, compiled from public 2026 rankings.
In class it powers grouping and aggregation exercises — and a healthy discussion about how estimated a “net worth estimate” really is. A dirtier sibling of this file appears in data-cleaning exercises.

Course style guide rule: cite the dataset name, provider, and the date you accessed it — e.g. "World Billionaires (2026). Course data catalog, courses.langd0n.com. Accessed [date]." If the entry names an upstream source (a city portal, a public agency), cite that too.
