2. Summary charts for price indices

Figure 1: Monthly price indices for agricultural outputs and inputs to December 2023 (2020 = 100)

Figure 1 illustrates monthly price indices for agricultural outputs and inputs since January 2020. The price indices for both agricultural outputs and inputs began rising steeply around autumn 2021.

The index for output prices peaked a few months after that for input prices, towards the end of 2022, and has remained below the input prices since mid-2021. Despite recent declines in the indices for outputs and inputs, both remain considerably higher than the 2020 baseline.

Figure 2: Annual average price indices for agricultural outputs and inputs to December 2023 (2020 = 100)

Figure 2 shows the annual average price indices for agricultural outputs and agricultural inputs since 2020. In 2023 (to date), the annual average price index increased by 1.4% for agricultural outputs and decreased by 5.3% for agricultural inputs. The year with the largest difference between the agricultural outputs and agricultural inputs was 2022, with 2023 showing the second largest difference.

Year	All agricultural outputs	All agricultural inputs
2020	100.0	100.0
2021	109.9	111.4
2022	130.6	143.2
2023	132.4	135.6

• improved weighting methodology.

About these statistics

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 March 2023 index was the first to be produced using weights based on 2020, replacing weights based on 2015.

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.
