Staying at home as much as possible to help flatten the curve of the novel coronavirus, people are relying on food and grocery deliveries more than ever.

A new FitRated survey shows how much people have come to rely on those services — and just how much it’s costing.

After surveying more than 1,000 people who used and didn’t use food delivery services, FitRated uncovered some data about American food delivery habits.

Here are some of the findings:

  • Baby Boomers are most likely to have their groceries delivered.
  • Millennials are more likely to have food from a restaurant delivered.
  • Out of the 73% of respondents who used delivery services, the average ordered food from a restaurant eight times a month, and groceries five times a month.
  • The most popular food delivery app was GrubHub, which 66% of the respondents used.
  • DoorDash came in second with 60%, and UberEats followed closely behind with 59%.
  • The most popular grocery service was Amazon Fresh, which 31% of the people surveyed used. Instacart was second with 27%.
  • While using a food delivery app helped free up time for family, work, exercise and household chores, the study found that the free time came with a cost — an average of $242 per month.
  • App users took fewer trips to the grocery store each month than those who didn’t use food or grocery delivery, but only 28% of delivery app users said it was easy for them to find healthy options to order.

In the next five years, the online food delivery industry is expected to grow to $200 billion, according to Forbes.
