Dataset details: Aerospace and Electronic Cost Indices, August 2012 Dataset

Cost indices (purchase of materials and fuels, average weekly earnings, general expenses and combined costs) relating to four aerospace and electronics industries. The data are based on the Standard Industrial Classification SIC (2007) and are calculated on a base year of 2005=100. The indices are widely used by government and business as an authoritative source of information on inflation, cost adjusting and price variation in trading contracts.

Indices for the latest two months are always provisional and flagged with a "p" marker due to the level of imputation present for items where the latest prices are not available. This level of imputation reduces significantly for earlier months, allowing index data to be published as firm values.

Occasionally, new information produces a change in the value of an index already published as firm. Where change is significant, index values are recalculated and annotated with an "r" marker.
