Newly-published US Census information indicates that the number of self-employed small business owners rose by one million between 2006 and 2007.
According to the organisation, the total of non-employee businesses reached 21.7 million during this period.
Harvey Monk, associate director for economic programs at the US Census Bureau, commented: "Businesses can use this data to help analyze market potential, to measure the effectiveness of sales and advertising programs and to develop their budgets.
"These statistics allow users to track annual trends in non-employee businesses down to the local level."
The department went on to say real estate services, professional, technical and scientific services, and specialty trade contractors accounted for 40 per cent of the receipts among these firms.
Earlier this week, technology provider D&H Distributing stated that effective data classification is vital to ensure companies maximize their sales in the current economic climate.
The group added that data quality solutions can enable companies to market themselves, convey value and increase sales in the downturn.
