The indicators are calculated using a chain index: industry-level volume indices are weighted by the structure of nominal investment in the previous year, meaning that the weights are updated annually; the cumulative indicator is obtained by multiplying the annual indices. The index reconstructed in this way across all 85 categories is +35.8%, slightly below the official figure of +37.9% due to Rosstat’s aggregation methodology and differences in industry-specific deflators. * The calculation excludes three OKVED groups with high exposure to military-industrial demand: manufacture of fabricated metal products (25), manufacture of computer, electronic and optical products (26), and manufacture of other transport equipment (30).
