The statistical picture of population aging in towns of Wielkopolskie Province: TERYT and DE-GURBA perspectives

Abstract

Aim/purpose-The aim of the paper is to compare the statistical picture of aging of the urban population of the Wielkopolskie Province in terms of two typologies: TERYT and DEGURBA. Design/methodology/approach-Selected demographic aging measures for years 2010 and 2016 were calculated for 112 towns according to TERYT typology and for 53 urban areas according to DEGURBA classification. The demographic aging measures were the following: median age, parent support ratio, aging index, elderly dependency ratio, proportion of population aged 65 and over and total dependency ratio. Findings-TERYT classification using the formal and legal status of the city gives a slightly different picture in relation to urban areas defined based on the DEGURBA classification. The results obtained showed that the population aging process was slightly less intense in urban areas in 2016 according to the DEGURBA typology, compared with the indicators for the city group separated on the basis of the TERYT register identifier. Research implications/limitations-The results obtained are promising. The implications of the approach presented are at least twofold. At the methodological level, the paper presents an alternative possibility of distinguishing urban areas based on the DEGURBA classification in relation to the TERYT classification. However, in the cognitive layer, it shows differences in the aging of urban areas distinguished on the basis of these two classifications. These implications are limited only to the so-called traditional demographic aging measures and to urban population in the Wielkopolskie Province. To overcome these limitations further analysis should include, first of all, extending the research to the whole country.

What Is Urban after All? A Critical Review of Measuring and Mapping Urban Typologies in Portugal

“…The usefulness of these administrative units is undeniable since they allow their inhabitants to benefit from a local administration and budgetary facility associated with their territory [60]. However, as seen throughout the research and supported by other studies [61], parishes are far from being homogeneous units; their own internal differences are often expressed through many essential aspects, such as a wide range of situations that vary from densely artificialized to natural landscapes, thus providing distinct land uses, degrees of occupation, population densities and, accordingly, urban or rural characters. In large cities and compact urban areas, parishes naturally tend to be homogeneous (in terms of urban land uses) since they constitute a part of the city's fabric.…”

“…For several decades, European society, including that of Poland, has been accompanied by the phenomenon of population ageing [1][2][3][4][5][6][7][8]. This process is manifested by changes in the age structure of the overall population as a continuous increase in the proportion of older people and a decrease in the proportion of people of working age.…”
