How Many Family Offices Are There in the World?

Nobody knows the exact number, and any figure that claims to is overstating its certainty. Family offices are private, opaque and defined differently by everyone who counts them. But the estimates cluster usefully.

The number

Deloitte produces one of the more precise counts: roughly 8,030 single-family offices worldwide, up from about 6,130 in 2019, and projected to grow to more than 10,720 by 2030, a 75 percent increase in just over a decade. Broader estimates, which include informal, embedded and virtual arrangements, run as high as 20,000. The gap is not sloppiness; it is definition. Count only dedicated, staffed single-family offices and you get the lower number. Count every structure a wealthy family uses to manage its affairs and you approach the higher one.

The assets

Total assets under management are estimated between about 3.1 trillion dollars (Deloitte) and, on broader measures, 5 to 10 trillion. Deloitte projects the figure will reach 5.4 trillion by 2030. Individually, the average single-family office manages roughly 1 billion dollars, against an average family net worth of about 2.7 billion, according to the UBS Global Family Office Report 2026. The distribution is top-heavy: a handful of giant offices account for a large share of the total.

Where they are

By region, North America leads with about 3,180 offices, roughly 40 percent of the global total, followed by Asia-Pacific (about 2,290) and Europe (about 2,020), with the Middle East, South America and Africa making up the rest. The United States dominates as a single jurisdiction. But the momentum is in Asia-Pacific, now the fastest-growing region for new family-office formation, driven by a generation of newly created wealth.

Why the numbers keep rising

Behind the growth is the largest wealth transfer in history: an estimated 84 trillion dollars of US household wealth passing between generations by 2045 (Cerulli), with large sums also in motion elsewhere. As that wealth moves, and as more of it is newly created rather than inherited, the number of families building an office to manage and preserve it keeps climbing. Treat every specific figure as an order of magnitude, not a fact, but the direction is not in doubt.
