In today's world, most companies span several regions and sell across the world. As my Foolish colleague Morgan Housel notes, 10 years ago, less than a third of S&P 500 revenue growth came from abroad. Today, that area makes up half of the S&P 500's growth.

And that number is growing. The truth is, investors regularly underestimate how much demand comes from abroad. More importantly, for large, multinational corporations that have already established a presence in their home markets, much of their future growth comes from abroad.

With that in mind, today we're looking at Accenture (NYSE: ACN). We'll examine not only where its sales and earnings come from, but how its sales abroad have changed over time.

Where Accenture's sales were three years ago
Three years ago, Accenture produced 42% of its sales within the Americas. Its Europe, Middle East, and Africa segment was actually the company's largest geography with 49% of company sales.

Where Accenture's sales are today
Today, the Americas have taken over as Accenture's largest segment. Not only that, but Asia is becoming an important region for the company.

While the chart above might not make Asia's jump look particularly impressive, it's important to remember that Asia is growing off a small base. Its growth rate dwarfs the Americas in recent years, while Europe has actually seen sales sag.

Europe, the Middle East and Africa (EMEA)

Asia Pacific

58%

Accenture's profile isn't terribly different than global competitor IBM (NYSE: IBM). Big Blue continually trumpets sales growth in "Growth Markets" while major markets like the United States see lower growth rates and focus on earnings growth through margin expansion. As an example, last quarter, IBM saw sales grow 7% in Growth Markets (and 10% in BRIC countries) while major markets saw flat sales growth.

An interesting peer in the space is actually Cognizant (Nasdaq: CTSH). The company has seen sales soar 329% in the past five years. You'd expect a services company with that kind of growth to be seeing global growth, but Cognizant has seen its sales explode predominately in the U.S. and U.K. The two nations account for 90% of the company's sales.

In the end, while the Asia-Pacific region still accounts for just 13% of Accenture's sales, its future sales growth looks increasingly intertwined with its prospects in the region.
