The Electronic Commerce — or e-commerce — industry is evolving very rapidly, so data collection and evaluation are particularly difficult. Consequently, one has to rely largely on surveys by both government and private agencies.
According to the U.S. Census Bureau, the manufacturing sector is relatively more reliant on e-commerce (51.9% of their total shipments), followed by merchant wholesalers (26.4% of their total sales). These two segments make up the business-to-business (B2B) category.
Retailers and service providers generated just 5.2% and 3.1%, respectively of their revenues online, with retailers growing faster than service providers. The Bureau categorizes these two segments as business-to-consumer (B2C).
All except the services segment grew around 5% over the prior year. Services grew 4%. [All the above data from the U.S. Census Bureau relate to 2012, as published in May 2014].
The U.S. Commerce Department estimates that ecommerce sales in the country grew 16.9% in 2013 to reach $263.3 billion.
