Final answer:
Food sales declined during the 2007–2009 recession while sales of electronics increased.
Step-by-step explanation:
During the 2007–2009 recession, food sales declined by 5% in the United States, as measured by the Bureau of Labor Statistics' Consumer Expenditure Survey. This indicates that people were not spending more on groceries despite the economic downturn. On the other hand, sales of electronics saw a universal increase, with an 18% uptick in the United States, specifically. People around the world tend to demand more electronics during tough economic times because they provide entertainment and are seen as essential for communication and staying connected.
