Statistics Poland celebrates its centenary this year. The history of the Office has been marked not only by a number of significant changes concerning the organisation and functioning, but also by the sustainability of its objectives and principles. Focusing on continuous development, for one hundred years Statistics Poland has been consistently implementing its mission by providing reliable information to its users. The momentous jubilee of the Office became an inspiration for the preparation of an album entitled “Statistics Poland. 100 Years on Photographs”. Selected facts from the life of the Institution, showing the changes in its activity, were presented on the basis of photographs. They are complemented by short biographies of successive presidents of Statistics Poland.
