How is the calculation of the GDP carried out?

The GDP, Gross Domestic Product, is the set of all goods and services produced by a country in a given period: from agricultural products to cars, from ships to services provided by banks, insurance companies and public companies. "In short, this is a gigantic sum, " explains Alessandra Agostinelli of the Istat National Accounting Directorate.

In our country, the calculation of GDP is entrusted to Istat: it is a complex process, involving over 100 people. In fact, statisticians produce around 88, 000 intermediate numbers to reach the final result.

The sum includes everything that is produced in the country for over 100 different economic activities in which the production units are classified and for over 100 different types of goods and services.

The starting figures are the balance sheets of all the Italian industrial and service companies, deposited with the Chambers of Commerce or communicated to ISTAT in statistical surveys, Istat data on the agricultural sector, those of the Bank of Italy on banks and other institutions financial, the budgets of the insurance companies collected by ISVAP, the budgets of the Public Administrations, as well as a series of detailed information coming from some large companies or from trade associations.

To all this we must add the value of goods and services imported from abroad and an estimate of all the activities that, due to avoidance or evasion, are not declared.

This gives the total of the goods and services offered.

This value must be equal to the demand, that is to everything that is used or consumed within the country or exported: they are the costs of the enterprises (for example for the raw materials), the consumption of the families, the investments, the expense of the Public administrations.

These values ​​are estimated starting from the financial statements of companies and administrations, from ISTAT household surveys, from those on vehicle registrations or construction activities.

The GDP is therefore the result of the balance between supply and demand for goods and services.

Here's how it has evolved over the years (in US dollars at today's rate. Data not adequate to take inflation into account)
