No. The statistical information produced by Statistics Portugal is generally aimed at being released to the public. However, there are statistical operations (on the basis of which information is published) that may be aimed at obtaining indicators that support other statistical operations. In these cases, information may be used to produce other statistical operations, but it should not be published, given that it must be interpreted with caution. In addition, there is also information classified as confidential, which, although produced, must not be published, under the terms of the law. However, it may be used in the production of other statistics.
