The chart illustrates the total valuation of household expenditures in the USA in billions across three categories: groceries, electricity, and internet. From 2000 to 2007, households spent the most on groceries, followed by electricity and internet.
In 2000, over 70 billion US dollars was spent on groceries. For the next few years, this number grew gradually until it peaked in 2004 at 90 billion. The amount spent on groceries would decrease until 2007, where roughly 70 billion was spent. Therefore, groceries showed a parabolic trend, starting and ending at the same point and reaching its climax at the halfway mark.
Ranking second throughout the years, electricity showed an upwards trend. In 2000, under 40 billion was spent. This figure reached 50 billion in 2004, and surpassed 60 billion in 2007. Lastly, the amount spent on internet also showed an upwards trend, though its growth was more significant than that of electricity. In 2000, less than 5 billion dollars was spent on internet. The number grew slowly until it spiked to above 20 billion in 2006 and nearly 50 billion in 2008.
