Spending data from the Census shows that for the first time Americans spent more at restaurants than on buying food at grocery stores:

More than two decades ago, Americans spent $162 in groceries for every $100 they spent in restaurants. But this past January, they spent nearly equal amounts of money in both places: $50.475 billion in restaurants and bars, and $50.466 billion in grocery stores.

There are several social changes behind this:

Perry attributes the numbers to dropping gas prices, which have left many people with more disposable income. But it’s unlikely that a single factor is to thank for the trend. “I think it’s a combination of a recovering economy and changing eating habits,” he said, extrapolating that “the millennial generation [may be] more likely to eat out than cook at home.” Perry also noted that dining in restaurants simply isn’t the once-in-a-blue-moon event it used to be…

Martha Hoover, the founder of sprawling Indianapolis restaurant empire Patachou, goes one step further: Restaurants have earned a role in society that is equal to “work” or “home.”…

“We’ve seen a huge shift in San Francisco,” she told Yahoo Food. “I’ve seen people who treat restaurants like they do in New York City: as their kitchens.” Weinberg attributes the change to people working longer hours, leaving them with little time to prepare their own meals. Grocery shopping, too, can be a pricey proposition if one develops a predilection for organic and local fare.

In other words, home and family life has changed alongside different economic options. We might also see restaurants more as “third places” between work and home where people can socialize and pay for their meals in a comfortable in between space.
