Data sources and methodology


This is a sample survey.


In preparing estimates of an industry's production, all activities of establishments classified to the industry are included, that is, the "total activity" concept is used. In addition to GDP estimates, gross output and intermediate input estimates are prepared by industry. No attempt is made to eliminate transactions between establishments within the same industry, that is, to derive "net sector" estimates. The current price estimates of GDP at factor cost (or value added) by industry can be measured directly by summing the factor incomes and depreciation or indirectly by deducting the cost of the intermediate goods and services used in the production process from the value of gross production or output. The method adopted for any particular industry is determined by the availability of data. If possible, estimates based on both methods are prepared. Gross output is frequently estimated as the sum of sales and inventory change for finished goods and work-in-progress. Because the System of National Accounts uses an accrual method of valuation, typically the reported value of inventory change must be adjusted by the amount of the change which can be attributed to changes in prices (this is called the "inventory valuation adjustment"). The revalued inventory change is called "the value of the physical change" in inventories. Similarly, intermediate inputs must be adjusted to take into account the extent to which raw materials used in production during the current period were purchased in a previous period. For any industry, gross output can be described as the total of all costs, intermediate and factor. In some cases, particularly for the non-commercial industries, data on gross output are not available and must be estimated indirectly as the sum of total costs. In many of these industries data on intermediate inputs are not available on an establishment basis so that GDP has been used as a proxy for gross output. It should be noted that for trade, the gross output is the total value of sales, rather than the gross margin. This applies also to secondary trading activity in other industries. Constant price series represent the revaluation of quantities of production using prices of a base period. In principle constant price data should be derived by deflating current price data by a currently weighted (Paasche) price index to yield a base-weighted (Laspeyres) quantum series. Constant dollar data for individual commodities may also be derived by multiplying current period quantities of production by their price in the base year. The constant dollar data for gross output or intermediate inputs is the sum of the values for the individual commodities. The constant price series for GDP is derived as the difference between gross output and intermediate inputs in constant prices. This technique is called "double deflation". For some industries, data limitations do not permit the use of the double deflation technique. In these cases, the constant price estimates of GDP may be based on the movement of gross output or intermediate inputs by assuming a fixed relationship between gross output and intermediate inputs.
