Online shopping has taken over many corners of the retail world, but not grocery.

Just 4 percent of Americans buy groceries online on at least a weekly basis, according to new Gallup survey data. And 84 percent of those polled said they never buy groceries online.

About 1 percent of shoppers buy groceries online more than once a week, 3 percent once a week, 5 percent once or twice a month, 3 percent a few times a year and 3 percent less often than a few times a year.

By contrast, according to Gallup, 83 percent of Americans go to a brick-and-mortar store at least once a week to buy groceries. Thirty-six percent go more than once a week, 47 percent once a week, 15 percent once or twice a month, 1 percent a few times a year and 1 percent never.

Younger people are more likely to buy groceries online. Fifteen percent of Americans aged 18 to 29 did so at least monthly, compared to 12 percent of those 30 to 49, 10 percent of those 50 to 64 and 2 percent of those 65 and older.

Those who live in the East and in cities also buy more groceries online. Sixteen percent of Easterners did so at least once a month, compared to 11 percent of Westerners, 8 percent of Southerners and 5 percent of Midwesterners. Fifteen percent of Americans who live in big or small cities bought groceries online; 8 percent of suburbanites and 6 percent of those in towns and rural areas did so.

The poll results are part of Gallup’s annual Consumption Habits survey, conducted July 5-9.
