The new law laying down the principles, rules and structure of the National Statistical System (SEN) was adopted in 2008. Article 4 (Statistical Authority) makes it compulsory to respond to surveys conducted by the National Institute of Statistics (INE), within the set deadlines. It also defines the penalties to be imposed in the event of non-compliance (no response, late response or incorrect response).
In Portugal, the main public agency for statistics is the National Institute of Statistics (INE). Its task is to produce and publish high-quality official statistical information.
The INE delegates some of the country’s statistical work to other national bodies (ministries, institutes, national bank, etc.). It coordinates these activities and publishes the information produced.
The statistical authorities can require any bodies, services, businesses or individuals to provide the data needed to produce national statistics.
Types of statistics
Businesses operating in Portugal must submit a series of data to the Ministry of Labour and Social Solidarity (MTSS).
The MTSS, through the Working Conditions Authority (ACT) and the Office for Strategy and Planning (GEP), has designed a Simplified Information System on Employment and Working Conditions, which is referred to as the Comprehensive Report.
Businesses must submit the annual Comprehensive Report for the previous year, between 16 March and 15 April.
The National Institute of Statistics (INE) conducts a series of compulsory surveys. Businesses can respond to these surveys on the Surveys page of the WebInq service, using a username and password.
The Law on the National Statistical System makes it compulsory to respond to surveys conducted by the INE and imposes penalties in the event of non-compliance.
Most surveys conducted by the INE involve a representative sample taken from the universe to be studied. As a result, a statistical unit located in a small region or belonging to a sector of activity with few operating units has more chance of being involved in multiple surveys, as is also the case with a large statistical unit.
The Ministry of Labour and Social Solidarity (MTSS) analyses statistical data and provides statistical information on industrial accidents, social reporting, working conditions, structured employment, vocational training, strikes, staff lists and pay.
The MTSS also publishes an on-line monthly Statistical Bulletin covering the main areas of business, as well as statistics based on information taken from staff lists.
