Figures to January 2023 (published 23 March 2023)

Updated 21 March 2024

The Agricultural Price Index (API) is an index of the price of agricultural outputs and inputs for the UK used to track change over time. More details on the index, including how it is produced, are in the Background section at the end of this document.

Outputs

  • The price index for agricultural outputs increased by 17.1% in the 12 months to January 2023.
  • The largest upward contribution to the 12-month inflation rate for agricultural outputs was milk (8.0 percentage points), followed by pigs (2.4 percentage points), and wheat (2.3 percentage points).
  • The largest downward contribution to the 12-month inflation rate for agricultural outputs was sheep and lambs (-0.9 percentage points), followed by fresh fruit (-0.7 percentage points), and oilseed rape (-0.6 percentage points).

2. Summary charts for price indices

Figure 1: Monthly price indices for agricultural outputs and inputs, January 2015 to January 2023 (2015 = 100)

Figure 1 shows the monthly price indices for agricultural outputs and inputs from January 2015 to January 2023. Overall, the price index for agricultural outputs tends to be more volatile than that for agricultural inputs, though both series have displayed considerable volatility in recent times. The price index for agricultural outputs has seen a period of fluctuation in recent months, following a period of very strong inflation in the year prior to this. Agricultural inputs have seen very strong price inflation throughout 2021 and the first half of 2022, but prices have since decreased.

Figure 2: Annual average price indices for agricultural outputs and inputs to January 2023 (2015 = 100)

Figure 2 shows the annual average price indices for agricultural outputs and agricultural inputs since 2015. In 2022, the annual average price index was 19.8% higher for agricultural outputs and 27.7% higher for agricultural inputs than in 2021. In 2023 (to date), the average price index is 3.8% higher for agricultural outputs and 1.6% higher for agricultural inputs than the average for 2022. In recent months, the overall price index for inputs was higher than that for outputs, but this trend has now reversed.

4. Contributions to the annual agricultural outputs and inputs inflation rates

Figure 5: Contributions to the 12-month inflation rate in agricultural outputs, UK, January 2022 to January 2023

Figure 5 shows the extent to which different agricultural commodity categories have contributed to the 12-month inflation rate for all agricultural outputs over the last year. The inflation rate for agricultural outputs has fluctuated between 12.0% and 25.8% since January 2022, with the main contributors varying for different months. Most recently, the 12-month inflation rate in January 2023 saw upward contributions from all output commodity categories except industrial and other crops, which recorded a slight downward contribution. This was the fourth consecutive month to record a decrease in the agricultural outputs inflation rate.

Figure 5: Contributions to the 12-month inflation rate in agricultural outputs, UK, January 2022 to January 2023

Figure 6: Contributions to the 12-month inflation rate in agricultural inputs, UK, January 2022 to January 2023

Figure 6 shows the extent to which different agricultural inputs have contributed to the 12-month inflation rate for all agricultural inputs over the last year. The 12-month inflation rate for agricultural inputs has fluctuated between 15.1% and 33.7% in the last year. Agricultural inputs have seen exceptionally high inflation rates in the past year, but prices are stabilising amid large falls in wholesale gas prices and considerable price falls in the components of animal feed. In particular, fertilisers have seen very high inflation rates in the last year, and while prices remain considerably above 2021 levels, inflation rates have slowed considerably.

About these statistics

Revisions

  • Price index for eggs revised for January 2022 to December 2022.

Background

The output series reflects the price farmers receive for their products, also referred to as farm gate price. Information is collected for all major crops (for example wheat and potatoes) and livestock and animal products (for example sheep, milk and eggs).

The input series reflects the price farmers pay for goods and services. The series is in two groups: goods and services currently consumed; and goods and services contributing to investment. Goods and services currently consumed refer to items that are used up in the production process, for example fertiliser or seed. Goods and services contributing to investment relate to items that are required but not consumed in the production process, such as tractors or buildings.

Data uses

Farmers use the Agricultural Price Index to help set prices for their outputs and monitor the prices paid for inputs. Analysts in Government, industry specialists, consultants, economists and academics use the data to assess the impact that price changes have on industry and consumers.

The Office of National Statistics (ONS) uses API data in the production of the Producer Price Index (PPI), which is one of the key measures of inflation.

Methodology

Price data

Defra collect prices from a wide variety of sources to produce the monthly API. This includes data from our own surveys, information from the Horticultural Marketing Inspectorate (HMI), Agricultural and Horticultural Development Board (AHDB), and the ONS. For some items we only receive quarterly or annual data, for example, electricity prices. When no new data are available estimates are made based on previous values until new data becomes available. When new data become available, historical revisions are made and a note is added in the ‘What you need to know about this release’ section.

In order to maintain continuity in these statistics, the Agricultural Price Index is produced in accordance with the European Statistical System.

Weights

Each price point is assigned a weight which reflects its contribution to the overall index. The weights for each item represent their annual monetary value from the Agricultural Accounts. For example, if the annual value of animal feed purchased is three times more than fertilisers then the annual weight for animal feed will also be three times more than for fertiliser. Where monthly data is available, monthly and quarterly weights for outputs reflect the pattern of sales volumes across the year. For example, if the volume of sales for apples in October is double that in June, then the October weight for apples is double the weight for June. Monthly and quarterly weights for input items do not vary within the year. The weights are recalculated every five years to reflect more recent data. The April 2018 index was the first to be produced using weights based on 2015, replacing weights based on 2010.

Contributions

It is often of interest to estimate the effect of a group or item on the change in the agricultural outputs or inputs index. The contribution of a group or item to a change in the all items index over a given period of time is defined as the change that would have occurred in the all items index if that component had undergone its observed change but all other component indices had remained frozen at their values at the start of the period (and all weights are kept the same). The effect of each component depends on both the size of its change and its weight.

The formula for calculating the contributions to changes in the agricultural inputs inflation rate differs from the agricultural outputs inflation rate, reflecting the fact that monthly and quarterly weights for input items do not vary within the year. The formulas for calculating contributions to changes in all items index with seasonal and non-seasonal weights can be found in the 2007 Technical Manual on Consumer Price Indices published by the ONS.

The categories shown in Figure 5 and 6 were created by aggregating the following categories:

  • Fresh fruit, fresh vegetables, flowers and plants, and potatoes into horticulture.

  • Industrial crops, forage plants and other crop products into industrial and other crops.

  • Fertilisers and soil improvers, plant protection products and seeds into crop-related costs.

  • Animal feedingstuffs and veterinary services into livestock-related costs.

  • Maintenance of buildings, maintenance of materials, other goods and services, buildings and materials into other farm costs.
