The NIESR GDP Estimate is measured by the National Institute of Economic and Social Research. It is an informal monthly measurement of gross domestic products based on published data and statistical model. It measures the adjustment in the projected value of all goods and services manufactured in the United Kingdom during the previous three months.
The calculations cover the main five conditional sectors of the United Kingdom economy, agriculture, industry, construction, public services (health, education, administration, and defence) and private services. The monthly index of GDP estimate is based on these five sectors.
The NIESR GDP Estimate is released three weeks earlier the approved quarterly statics release and is interpreted by experts as an initial alternative gross domestic product forecast. However, the indicator does have a substantial influence on the quotes of the pound sterling, since it frequently works as an initial guide for traders before the release of official quarterly statistics.
