The publication entitled Wielkopolskie Voivodship. Subregions – Powiats – Gminas has been appearing for several years as a supplement to the Statistical Yearbook of the Wielkopolskie Voivodship. Published alongside the Yearbook, the publication provides an up-to-date overview of the Wielkopolskie Voivodship in the light of the socio-economic situation of its territorial units. Figures in this year’s edition reflect the state of gminas, powiats and subregions in 2012.

In terms of thematic contents, the publication Wielkopolskie Voivodship 2013. Subregions – Powiats – Gminas resembles the previous editions. The structure of the current edition, in contrast, is the result of standardisation efforts undertaken to unify the yearbooks. Work in this area was intended to standardize names of sections and table headings, update information contained in notes and footnotes, introduce a uniform set of variables, use the same scope and manner of data presentation and territorial cross-sectional cells, as well as developing more precise concept definitions.

The publication Wielkopolskie Voivodship 2013. Subregions – Powiats – Gminas starts with overview tables presenting selected data about the voivodship in 2000 and the period of 2005–2012, and providing information about the ranking of powiats and subregions in 2005 and 2012. The main part of the publication consists of thematic tables with data for 2012 at the lowest possible level of territorial division. In contrast to the previous editions, the general remarks are placed directly prior to each major topic group of tables, mirroring the convention adopted in the Statistical Yearbook of the Wielkopolskie Voivodship 2013.

Recommending the another volume of Wielkopolskie Voivodship 2013. Subregions – Powiats – Gminas with a new layout, I hope that it will meet readers’ expectations and provide a source of knowledge about the degree of internal diversification of the Wielkopolskie Voivodship and about the current socio-economic situation of its powiats and gminas.
