The Regions

In our annual Regional Leaders report, we rank the top firms in these economic ecosystems, but not the ecosystems themselves—that’s what this slide show is for. Here, ranked by the overall growth of their top firms in 2011, are the best regions in which to run an accounting firm. (For our Regional Leaders and Top 100 Firms report, visit our Rankings section -- see tab above.)

1. The Gulf Coast

Alabama, Florida, Louisiana and Mississippi

Growth: 19.22%

Top Firm: Carr, Riggs & Ingram (Enterprise, Ala.; $100.31 in 2011 revenue)

Fastest-Growing Firm: Warren Averett (Birmingham, Ala.; grew 127.9%)

The Gulf Coast's double-digit growth is largely down to the three-way merger of midsized firms that created the new Warren Averett, as well as M&A at the region's leader, CRI, but all of our firms here grew their revenues.

Growth:18.37%

Top Firm: Dixon Hughes Goodman (Charlotte, N.C.; $295 million in 2011 revenue)

Fastest-Growing Firm: DHG (grew 52.85%)

The Southeast's high level of growth is also due, in part, to some major mergers, led by the creation of Dixon Hughes Goodman from Dixon Hughes and Goodman & Co.

Home to a significant portion of our Top 100 Firms, the Mid-Atlantic Region also claims a large share of accounting revenue -- and most of the firms here display strong, consistent growth.

8. The Mountain Region

Colorado, Idaho, Montana, Utah and Wyoming

Growth: 2.27% 2.27%

Top Firm: Ehhardt Keefe Steiner & Hottman (Denver; $58.47 million in 2011 revenue)

9. The Southwest

Arizona, New Mexico, Oklahoma and Texas

Growth: 1.96%

Fastest-Growing Firm: Whitley Penn (Fort Worth; grew 16.82%)

10. The Midwest

Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota and South Dakota

Growth: 1.11%

Top Firm: BKD (Springfield, Mo.; $391.2 million in 2011 revenue)

Fastest-Growing Firm: RubinBrown (St. Louis; grew 13.73%)

The Midwest lagged the rest of the regions, and even managed to grow less in 2011 than it did in 2011. Growth rates at most firms were fairly meager -- St. Louis' RubinBrown broke the trend, but some of that is no doubt due to its aggressive expansion in Colorado.
