Food stockpiling statistics show that keeping extra food at home varies sharply by the definition of an emergency reserve, the household’s location, and the disruption being measured. Recent UK data found that 85% of respondents had at least three days of non-perishable food that did not require cooking, while only 25% had at least seven days. During the COVID-19 pandemic, food-at-home retail sales in the United States briefly rose more than 50% above comparable 2019 weeks.

Household emergency food reserves
The UK Public Survey of Risk Perception, Resilience and Preparedness 2026 distinguishes between a short reserve and a larger stockpile. In 2026, 60% of UK respondents said their household had about three days of non-perishable food that did not require cooking. The same survey found that 85% reported at least three days of non-perishable food stored at home, while 25% reported at least seven days.
The measures are not identical: the three-day figure above includes food that does not require cooking, while the broader at-least-three-days measure concerns cupboard-storable non-perishable food without that no-cooking restriction. That definition difference matters when comparing preparedness claims.
At the shorter end of the range, 7% of UK respondents reported having one day of non-perishable food at home in 2026. The survey therefore describes a wide spread between households with a minimal reserve and those maintaining a week or more.
Households with babies showed a different pattern for formula. Among UK respondents with a formula-fed baby under 12 months, 57% reported having seven or more days of baby formula at home, while 2% reported one day’s worth. These estimates are based on 112 respondents, so they are small-sample descriptive statistics rather than a precise measure for all households.
Older US evidence provides a longer historical perspective, but it should not be treated as a current benchmark. In the USDA household pantry study, a 1964 survey asked how long stored food would last under a minimum-food scenario, not during normal meal consumption. About one-third of households said their stored food would last one week or less, and another one-third said it would last between one and two weeks.
The historical results also varied by community type. The USDA study estimated that 70% of downtown big-city households would run through their food supplies within two weeks or less, compared with 59% of suburban households and 39% of farm households. These figures describe the 1964 study population and its definitions; they are not independently verified modern estimates.
Water, drinks, and supporting supplies
Food reserves are only one part of household preparedness. In the UK 2026 survey, 40% of respondents said they had enough non-refrigerated drinks, excluding water and alcohol, for three days. Separately, 37% said they had enough bottled water for three days.
When the survey applied an allowance of 3 litres per person per day, only 4% of UK respondents had at least three days of bottled water for their household. A further 10% had one day of bottled water, while 82% had less than one day under that allowance. The difference between the general bottled-water answer and the calculated household allowance shows why reserve statistics need a clear quantity definition.
Other supplies were more common. In 2026, 19% of UK respondents reported having a camping stove at home and 17% reported growing fruit or vegetables themselves. Household hygiene and first-aid items were reported more often: 71% had hand sanitiser, 68% had wet wipes, and 63% had a first-aid supplies kit.
Medication reserves were also measured. Among UK respondents taking essential medicine for an ongoing condition, 76% said they had at least seven days of that medicine. This is a separate preparedness measure from food stockpiling, but it helps show how households’ reserves extend beyond pantry ingredients.
How households stockpiled during disruptions
Early-pandemic behavior in Great Britain shows how quickly stockpiling can become a shared expectation. In the Office for National Statistics report from 9 April 2020, covering 20–30 March 2020, 32.8% of adults said they had purchased extra supplies, groceries, and toiletries. Yet 98.5% thought other people had purchased extra groceries and toiletries.
Support networks also shaped how households approached disruption. During the same period, 50.6% of Great Britain adults said someone had offered to organise or bring food and essentials if they had to self-isolate or became unwell. Among adults aged 70 and over, the figure was 83.3%.
By 26–30 August 2020, 37% of Great Britain adults reported shopping around less than usual across different places when buying food and toiletries. Among those who shopped around less, 64% said feeling safer buying everything in one or fewer places was the most common reason.
The financial context was significant. In that August 2020 period, 22% of Great Britain adults said the pandemic was affecting their household finances. Among adults whose finances were affected, 66% cited reduced income, and 25% expected their household financial position to get a little or a lot worse over the following 12 months. These figures help put extra purchasing in context: the ability to build reserves was not distributed evenly.
Food shortages and changes to shopping
Shortage experience changed across two Great Britain survey periods in autumn 2021. The figures below come from the ONS reports for 8–19 September 2021 and 6–17 October 2021.
| Food-shopping experience | 8–19 Sep 2021 | 6–17 Oct 2021 |
|---|---|---|
| Could not buy essential food because it was unavailable | 18% | 16% |
| Could not buy other non-essential food because it was unavailable | 25% | 23% |
| Everything needed was available | 61% | 47% |
| Experienced some difference from usual | 58% | 61% |
| Reported less variety in shops | 40% | 43% |
| Found a replacement for unavailable food | 20% | 21% |
In the September period, 20% said needed food items were unavailable and they could not find a replacement, while 13% had to visit more shops than usual to get what they needed. In October, 85% reported that their food-shopping habits had not changed in the two weeks ending 17 October. The shortage questions can overlap because respondents could select more than one experience, so the percentages should not be added together.
The pattern is useful for pantry planning: an unavailable item does not always mean a complete inability to shop. Some households found replacements, some encountered less variety, and some needed additional store visits. Stockpiling statistics therefore capture both the quantity held at home and the flexibility available when a preferred product is missing.
Retail food purchasing surges and normalization
US retail data recorded a sharp early-pandemic shift toward food purchased for consumption at home. According to the USDA Economic Research Service’s Food and Consumers series, US food-at-home retail sales were 57.5% higher than in the same weeks of 2019 during 9–15 March 2020. During 16–22 March 2020, sales were 56.2% higher than the comparable 2019 weeks.
The later data separates sales value from the number of units purchased. By the week ending 7 May 2023, US food retail sales value was 29.6% above the same week in 2019, but the quantity of food retail units purchased was 0.8% below the same week in 2019. Higher sales value and nearly unchanged unit volume are different signals; the figures do not establish that households were buying 29.6% more food.
Public food assistance also represented a larger share of food-at-home spending during the pandemic. The USDA ERS SNAP and P-EBT analysis reports that SNAP redemptions represented 6.8% of total US food-at-home expenditures in January and February 2020. SNAP and Pandemic Electronic Benefit Transfer together represented 11.7% from April through September 2020, nearly 5 percentage points higher than SNAP’s share in the same months of 2019.
The shift toward groceries was not permanent at its peak level. The USDA ERS food-at-home spending series found that inflation-adjusted US food-at-home spending in November 2023 was 2.7% higher than in November 2019. By comparison, inflation-adjusted food-away-from-home spending was 14.6% higher. Food-at-home spending averaged 7.2% above corresponding 2019 months during 2021 and 2022, while food-away-from-home spending averaged 8.7% above corresponding 2019 months from June 2021 through December 2022.
Pantry storage practices and barriers
Where food is stored can affect whether a reserve remains usable. In a 2022 UK Food Standards Agency university-student kitchen survey, 34% of respondents said they stored non-perishable food in a bedroom or another non-kitchen area. The same survey found that 9% stored chilled food at room temperature in a non-kitchen area and 6% stored frozen food at room temperature in a non-kitchen area.
The survey also measured food obtained from supermarket or shop bins or waste areas. Thirty-seven percent of respondents reported getting food this way, and 28% did so once a week or more often. These are university-student survey results from 2022, so they should not be generalized to every household or treated as a national pantry-storage estimate.
A practical barrier to building emergency reserves appeared in the UK 2026 preparedness survey: 25% of respondents said concern that products would go out of date and be thrown away prevented them from taking further emergency-preparedness steps. This helps explain why stockpiling is not simply a question of wanting more food at home. Storage location, temperature, household finances, product shelf life, and confidence in using supplies all shape the size and usefulness of a pantry reserve.
