The conclusion will underline the need for participatory formulation of AAL technologies and applications with older adults and the need for advocacy to promote the AAL in association with the concept of the "silver economy." 19.2 The Smart Cities and Communities in the Context of the Population Ageing: An Overview of the Concept At the beginning of the 21st century, the discourse on the revitalization of urban spaces is particularly important. Local administration, especially in urban areas, must meet the growing expectations of different groups of people (stakeholders) both as citizens and, among others, consumers, workers, entrepreneurs, investors, and members of families and communities. Furthermore, in the context of demographic change, urban renewal must include, among others, issues such as the population ageing, increasing the life expectancy, increasing pressure on the needs of people with disabilities regarding the elimination of architectural barriers and accessibility of public infrastructure, depopulation of some districts as well as unfavourable changes in birth rates, fertility, and mortality. According to the United Nations (UN), particularly noticeable is the process of "double ageing" of the population that is the rapid increase of old-old (75-84 years) and oldest-old (over 85 years) age groups in the population. The population of people over 80 years old is expected to grow worldwide from 120 million in 2013 to 392 million in 2050 [73]. In urban areas, these changes will be reflected primarily in the increased demand for care services, health services, and social services [17, 53, 54]. However, it should be noted that the population ageing not only significantly reduces the potential for the informal care provided mainly by families. This process also leads to the emergence of the "sandwich generation," that is defined mostly as people in middle age (40-59 years), who must reconcile their caring responsibilities towards their children and parents with maintaining a professional activity [1, 50]. The population ageing entails many consequences (social, economic, political, and cultural), but it is also a challenge to create new solutions so that societies can function better in the future. Attention, in particular, should be paid to older generations because the rate of population growth in the retirement age in CEE according to demographic projections will vigorously increase [85]. Poland, the Czech Republic, Hungary, and Slovakia (the countries of the Visegrad Group) in particular in recent years started to feel the effects of demographic changes through phenomena such as depopulation of large cities. This process is occurring mainly in centres, which concentrated industry during the period of real socialism, e.g., in Poland in the years 1995-2013 only six cities were characterised by an increase of population: Kraków, Olsztyn, Rzeszów, Warsaw, Zielona Góra, and Białystok [65]. However, the progressive urbanisation in CEE enforces implementation of new socio-technical solutions in the local ur...
