1.Introduction

Official statistics is currently facing a number of challenges, some of which are to do with the creation of a comprehensive system of information about cities and towns that could meet the needs of various users. Some of these challenges include the best possible exploitation of administrative registers and the use of smart data as alternative1 sources of data, a more flexible perception of the city as an important spatial element and the use of modern methods and tools of analysis.

As a part of the specialisation strategy, implemented in Polish official statistics at the start of 2009, the existing unit dealing with urban statistics in the Statistical Office in Poznań which became the Centre for Urban Statistics. The main idea of the specialisation strategy was to make each regional office responsible for conducting tasks for the whole country within specific fields. In other words, the regional offices were no longer limited to collecting data from a single province. Since its creation, the tasks of the Centre for Urban Statistics have focused on initiating surveys and formulating new methodological proposals for the statistical observation of cities and towns as well as conducting methodological studies aimed at delimiting and surveying areas that do not overlap with the country's administrative division.

The following paper addresses the challenges associated with the use of a more flexible approach to the perception of the city as an important spatial element in relation to the one based on the administrative division consisting of TERYT units (Szmytkie, 2018). The purpose of the paper is to compare the statistical picture of the aging process of the urban population of the Wielkopolskie Province using two typologies. One of them is based on the definition of a town in the Act of 29 August 2003 on official names of localities and physiographic objects (cf. Ustawa z dnia 29 sierpnia 2003 r. o urz&ecedil;dowych nazwach miejscowości i obiektów fizjograficznych, Article 2, Item 3). The second typology used in this study is the European classification of administrative units based on the degree of urbanisation - DEGURBA (Dijkstra & Poelman, 2014). The statistical picture of the aging process of the urban population of the Wielkopolskie Province has been created on the basis of six demographic measures of population aging: median age, parent support ratio, aging index, elderly dependency ratio, proportion of population aged 65 and over (% of total), total dependency ratio. The selection of these demographic measures was motivated by previous studies on this topic (GUS, 2015). In order to track changes over time, the data for 2016 are compared with those for 2010, which, in both cases, come from the Local Data Bank maintained by Statistics Poland.

Research motivations are at least threefold. The first of these results from the experience of cooperation on many national and international projects in which an attempt was made to relax the rigid treatment of the city only within its administrative boundaries, but a wider impact of a city was also considered, e.g. under the concept of the so-called larger urban zones (LUZ). The second motivation is related to taking up research problems related to the statistical activity of the Centre for Urban Statistics, and such undoubtedly includes the aging of the population which affects cities more than rural areas. Finally, there is also motivation related to the research interests of one of the authors, whose works devoted to comparing the TERYT and DEGURBA typology are one of the first in Poland.

The paper consists of six parts. After the introductory part, to show a wider perspective, in the section on the literature review, the key challenges facing official statistics in the context of urban analyses were presented including the use of administrative registers, alternative space divisions and the use of the kilometre grid concept. …
