Step-by-step explanation:
The student's question seems to revolve around the area of e-commerce retail sales as a percentage of total retail sales in 2010. This topic falls under the category of Business or Economics, and considering the nature of the data, it would typically be addressed at the college level, particularly in courses that cover the fundamentals of business statistics, business administration, or economics.
When analyzing the e-commerce trends, it is important to observe that while e-commerce represented about 25% of total retail sales in 2010, other economic factors such as corporate income tax revenue and excise taxes have shown a decrease as a percentage of GDP over the decades. The information also indicates that international trade and U.S. exports as a percentage of real GDP have increased significantly from 1960 to 2007. On the other hand, consumer expenditure surveys showed a decline in certain categories like food spending, indicating shifts in consumer behavior and economic conditions.
Surveys and censuses like those described, including those conducted by the Bureau of the Census and the Census Bureau, are crucial in collecting the data necessary to understand consumer trends and economic shifts. Such data helps in comprehending the production and availability of goods to consumers, the balance of trade, and the overall health of the economy.
