The Statistical Yearbook of Poznań City is the publication, which has its source in the twenties of the 20th century. Since 1999 it is released regularly in a two-year cycle. Every time this elaboration provides the data necessary for presenting the current numerical portrait of the capital of the Wielkopolskie Voivodship. This edition of the Yearbook contains information from the years 2010–2012. Everywhere, if possible, this time period was extended to data from 2005. In review tables a longer retrospection was applied, i.e. data for years 1980–2012 were presented. As regards substantial content of its merits, The Statistical Yearbook of Poznań City 2013 is a continuation of its previous editions. The domain tables, similarly as before, were grouped into twenty two subject matter chapters, and indices describing socio-economic situation of Poznań City were presented against the background of cities with 300 thous. or more inhabitants and in relation to relevant quantities for the voivodship and the country. The structure of The Statistical Yearbook of Poznań City 2013 refers to its counterpart for the voivodship. The changes resulting from an attempt to achieve consistency of publications of a yearbook type taken by all statistical offices were accomodated (they concerned, among others, uniformisation of names of chapters and titles of tables and updating information contained in remarks and footnotes).

NOTE: On 23/07/2015 the data in the table "Poznan against the background the towns with 300 thous. and more inhabitants" have been changed from the previously published.
