Latest Census Data Show Hope for Small BizIt's no surprise that during America's protracted recession, business closures and layoffs have been most severe in construction, finance and manufacturing. The U.S. Census Bureau released its 2010 business data at the end of June 2012,confirming this and more. The information offers a granular look into the particulars of what has happened to American business in this most recent documented period of economic stress.

That being said, you'll find more than the devil in the census details. With deeper analysis, some useful regional and local insights -- and even a few surprises -- emerge.

For instance, while the overall number of businesses nationwide declined from 2009 to 2010, the count of businesses in seven states and the District of Columbia actually grew by 8,000 -- while 43 states contracted by 45,000.

Industry by industry, state by state, and county by county, these fresh census figures offer business owners an in-depth look into what has transpired in their market area, including some useful clues about trends still underway.

The big picture
In this third year of decline (2009-2010), 36,837 businesses with paid employees shut down and more than 2.5 million jobs were lost nationally, leaving 7.4 million businesses standing. As severe as this might seem, it represents a marked slowdown from the decline experienced at the height of the recession (2008-2009). During that time, more than four times as many businesses (nearly 168,000) closed their doors, and more than twice the number of employees (6.4 million) were let go.

This accounts for all businesses, big and small. But small businesses, often closer to the brink, tend to face the most casualties in a recession. Businesses with fewer than 100 employees in the 2009-10 period accounted for 90 percent of closures -- a rate essentially unchanged from the prior year when 91 percent of closures were small businesses. The good news is that the rate of closures is down from the first year of the recession, when 97 percent of failures were small businesses.

The industry view
The 2010 data show that construction businesses experienced the largest decline, a year-over-year drop of 4.2 percent, followed by finance and insurance with a 3.2 percent decline, manufacturing (2.9 percent decline), management of companies and enterprises (1.4 percent decline) and wholesale trade (1.2 percent decline).

But the number of business establishments in certain sectors actually grew. Utility businesses saw an increase of 1.7 percent, as did health and social assistance firms. Numbers of businesses also grew in educational services (1.5 percent), accommodation and food services (1.4 percent) and professional, scientific and technical services (1.1 percent).

A tale of two states
The larger the area examined -- for example, major state economies such as California, Texas and New York -- the more its trends tended to look like the national averages, with slight but interesting variations. Natural resources, such as petroleum in the southern states, and legacy industries, such as automotive manufacturing in Michigan and Ohio, typically played a role in expansion and contraction.

However, population and resource diversity meant that changes were far from uniform when looking at smaller subsets of the data. To get an idea of some of the starker differences, here's a look at what happened to small business in Idaho, the state that lost the greatest percentage of businesses from 2009 to 2010, and in North Dakota, the state with the fastest rate of growth that year.

Idaho: 4 times the national small-business loss rate

One in 50 of Idaho's businesses with fewer than 100 employees shut their doors in 2010. Idaho's greatest contraction involved the construction sector, with closures running at 8.6 percent, twice the national average. The second-greatest drop was in the mining, quarrying, and oil and gas extraction sector, with a decline of 6 percent. Nationwide, however, businesses in this sector grew slightly.

In contrast, Idaho saw modest growth in the health care and social assistance sector, along with the arts, entertainment and recreation sector, and the accommodation and food services sector, businesses that support both a growing and an aging population. This parallels growth sectors seen throughout much of the U.S.

North Dakota -- growing on top of petroleum reserves
Increasing recoverable petroleum reserves and a national drive for energy independence helped North Dakota buck the U.S. trend of business decline in 2010. Indeed, at 1.9 percent growth, this Plains state won the small-business growth rate sweepstakes in the U.S. that year.

Small businesses in the mining, quarrying, and oil and gas extraction sector grew at a breakneck 13.5 percent pace, supported by transportation and warehousing businesses at 5 percent. Areas of decline were few and limited. With the lowest unemployment rate in the U.S. at 3 percent, North Dakota overall is an oasis of relative prosperity, albeit a limited one.
