Azerbaijan’s State Statistical Committee announced the new edition of its “Azerbaijan Industry 2026” yearbook on 1 October 2026. The yearbook contains multi-year tables on mining and quarrying, manufacturing, electricity, gas and steam production and distribution, and water and waste services. The figures discussed here cover calendar year 2025 and compare it with 2024; the 2026 publication date does not make them 2026 production results. The annual index table reports total industrial production at 99.1, meaning a 0.9% decline from the previous year at constant prices. For each annual comparison, the preceding year is set to 100.0; this is not a fixed index series with 2024 as the base for all years. An index movement in constant prices differs from a change in nominal production value measured in manats.

The fixed-price index aims to compare production volume by separating the effect of price change. Sectors have separated from each other. While the mining and quarrying index decreased by 2.4 percent, the index in crude oil and natural gas extraction decreased by 2.6 percent. The manufacturing index increased by 7.9 percent. These opposing aspects show that the country's industry does not consist of a single branch of activity. However, sector indices do not account for their contribution to the total index without being combined with weights.

Combining or averaging the percentage changes would add a calculation the source does not provide. The yearbook also includes information on industry’s place in the economy, production volumes, regional indicators and the physical output of selected products. The committee says its publication contains data suitable for cross-country comparisons. These are national and sector-level statistics, not company- or facility-level production reports. The product tables offer more detail, but the four indices summarized here do not support conclusions about individual companies. The 0.9% decline in total industry and the 7.9% increase in manufacturing cover the same period but different activities.

Manufacturing growth does not mean that total industry grew, and an overall index of 99.1 does not mean every manufactured product declined. The yearbook illustrates how aggregate results can conceal different movements among sub-sectors. Without the relevant weights, the precise contribution of each component cannot be calculated.

The index measures changes in the activity classes covered by the yearbook; it does not measure nominal manat values. Each figure is a separate year-on-year index: 99.1 for total industry, 97.6 for mining and quarrying, 97.4 for crude oil and natural-gas extraction, and 107.9 for manufacturing. These indices should not be added together or read as absolute output. Percentage changes alone also do not show each branch’s weight in total industry.
