Population ageing, together with urbanisation, has become one of the greatest challenges throughout the world in the 21st century. Approximately one million people turn 60 each month worldwide. By 2050, more than 20 per cent of the global population is predicted to be 60 years old or above. Thus, an increasing need is evident for age-friendly communities, services and structures. Numerous studies on age-friendly cities and communities (AFCCs) have been conducted over the past decade. The large volume literature makes it necessary to figure out key areas and the evolution trends of studies on AFCCs. Therefore, this paper aims to provide a comprehensive review of existing literature pertaining to AFCCs. A total of 231 collected publications are analysed and visualised by CiteSpace. According to the keywords and document co-citation networks that are generated, the foundation, hot topics and domains of AFCC research are grouped. Three major themes, namely the characteristics of AFCCs, the application of the World Health Organization's framework in urban and rural areas worldwide, and the measurement of cities’ and communities’ age-friendliness, are identified. In addition, a roadmap of AFCC research is developed. The results of this research will therefore benefit researchers and practitioners.

Purpose: This study aims to identify the stakeholders and critical factors (CFs) of promoting age-friendly communities (AFCs), discuss the relationship between the stakeholders and CFs and develop a preliminary framework for the briefing stage of promoting AFCs in urban China.Design/methodology/approach: Stakeholders and CFs were identified through literature review and document analysis. The Delphi method was used to screen the extracted stakeholders and CFs. The focus group methodology was applied to obtain evaluation matrices of relationships between stakeholders and CFs. A two-mode social network was formed to analyse the evaluation matrices generated.Findings: Results of the analyses indicate that local governments and policymaking institutions, together with project investors, obtained high prioritisations in the stakeholders' group, whilst senior citizens and caregivers appear to rank last. For CFs, communities' environmental factors receive the most attention from stakeholders.Research limitations/implications: Results of the analyses can only show similarities of the participating stakeholders' opinions on their concerns, and provide researchers and practitioners with initial ideas on analysing stakeholders and CFs at the briefing stage of promoting AFCs. For a specific project, the concerns and prioritisations would change. Diverse voices are necessary and case studies are in need.Practical implications: Challenges in promoting AFCs in urban China are discussed, and a preliminary framework of the briefing stage is developed for practitioners to follow when promoting AFCs.Originality/value: This study discusses which CFs should be considered priorities and what consensuses are generally reached by stakeholders. CFs are utilised to interpret stakeholders' relationships, influences and concerns on AFC projects when conducting the social network analysis (SNA).

Purpose: This study aims to identify senior citizens’ requirements related to “embedded retirement facilities (ERFs)”, which are small-scale, multi-functional and community-based care facilities for senior citizens in mainland China, and to discuss whether senior citizens’ perceptions are influenced by their backgrounds.Design/methodology/approach: A questionnaire type of research was administrated to gain senior citizens’ rankings of services that should be provided by ERFs. Non-parametric statistical models were applied to analyse the collected data.Findings: Results reveal that health care services for senior citizens are considered the most important. Requirements regarding rehabilitation and entertainment and daily life assistance are ranked second and third, respectively. Culture-related activities are the least important. Differences in the senior citizens’ background also influence their choices.Research limitations/implications: This research is based on a questionnaire survey completed in northeast China. Opinions from other areas of mainland China will be collected in the future study. Furthermore, the key items identified in this research, which was completed by participants from the built environment discipline, can be further elaborated by combining interdisciplinary feedback.Practical implications: This study explores services that are supposedly provided by ERFs. Findings will provide useful perceptions from senior citizens and will enable decision makers to prioritise services for senior citizens.Social implications: Although senior citizens are the end users of ERFs, their needs are easily overlooked. This study calls attention to their needs from ERFs, and the results are likely to serve as references for stakeholders in building improved facilities.Originality/value: ERFs have been provided in mainland China to cater to senior citizens’ needs since 2014. However, few studies have identified senior citizens’ requirements for provided services. The survey-based results of this work will serve as references for various stakeholders in making enhanced decisions.

Outdoor activity areas for embedded retirement facilities (ERFs) are essential for providing older adults with access to outdoor environments within communities. However, there is limited evidence on how these areas influence older adults’ spatial perceptions. This study investigated the impact of ERFs’ spatial characteristics on older adults’ physiological and psychological perceptions. Three kinds of outdoor activity areas in a coastal city in eastern China were investigated, and older adults’ physiological data were collected through real environments from wearable sensors. Their subjective perception data were collected through subjective satisfaction questionnaires. By combining them, the authors identified correlations between older adults’ spatial perceptions and the characteristics of outdoor activity areas, quantifying the impact of various spatial features on their satisfaction. The results showed that areas with high subjective satisfaction were linked to strong emotional arousal and increased visual comfort. Spaces with favourable sky view factors and spatial openness significantly enhanced spatial perception satisfaction. Key design elements can shape older adults’ spatial perceptions. This study highlights the positive relationship between outdoor activity areas for ERFs and older adults’ spatial experiences, offering insights for age-friendly renovations and site selection to create supportive environments for ageing populations.
