GDP by expenditure category is calculated as the sum of the final use of goods and services through final consumption, capital formation and exports less imports.
GDP by sector data is based on data derived from a variety of sources such as annual or periodic censuses and surveys and administrative records. Ad hoc surveys or special studies are also used for benchmark estimates or for deriving parameters for indirect estimation.
