---|---|---|---|---|---|---|---|---|
Numerator | Denominator | |||||||
Core | Outdoor Space and Buildings | Proportion of public restrooms that are kept clean and accessible. | Percentage of restrooms in parks and government facilities in a township or city that have accessible toilets and entrances and are regularly cleaned. | Number of public restrooms in parks and government facilities in a township or city that have accessible toilets and are regularly cleaned. | Total number of public restrooms in parks and government agencies in a township or city. | Corroborating evidence from surveys acquired by conducting field surveys in the township or city, recording data, and using demographic statistics, health statistics, and government open data websites for verification. | The provision of adequate, convenient, and accessible restrooms would encourage older adults and those with limited physical capacity to leave their homes, facilitate physical and mental recovery, improve physical and mental health, and reduce medical and social costs. | Among the daily life functions of older adults, the process of excretion (i.e., entering and exiting the restroom independently, maintaining posture, not soiling clothes, and putting on clothes) involves complicated and challenging physical coordination. Falls are the most common type of accident among older adults. The gap between the physical response and control expectations of older adults indirectly affects their willingness to use the restroom independently. To help older adults use toilets safely and confidently, adequate, convenient, safe, and accessible restrooms must be available. |
Core | Transporta tion | Availability of public transportation information. | Percentage of public transportation stations in a township and city, such as train stations, bus stations, mass rapid transit (MRT) stations, bus shelters, or bus stops that provide transportation information (e.g., paper pamphlets or Internet webpages) for people to consult. | Number of public transportation stations in a township or city (e.g., train stations, bus stations, MRT stations, bus shelters, or bus stops) that provide transportation information (portable pamphlets, Internet pages, and announcements). | Total number of public transportation stations in a township or city (train stations, bus stations, MRT stations, bus shelters, and bus stops). | Corroborating evidence from surveys acquired by conducting field surveys in the township or city, recording data, and using demographic statistics, health statistics, and government open data websites for verification. | Transportation information (timetables and routes) should be provided to older adults, and user-friendly public transportation systems should be developed to encourage older adults to move autonomously and increase their willingness to use public transportation. | Because older adults are more likely to fear or reject digital technology, they struggle to access transportation timetables in real time. When they must transfer at public transport stations, they usually need more time. Providing transportation information can help older adults use public transportation systems. |
Core | Transporta tion | Satisfaction with bus drivers’ attitudes. | Percentage of older adults surveyed who considered bus drivers to be friendly in the past year. | Number of survey respondents who reported that bus drivers were always or mostly friendly over the past year (non–bus riders were excluded). | Total number of people surveyed (non–bus riders are excluded). Suggested question: “Whenever you took a bus in the past year, did you find the driver friendly toward older passengers? Were they kind? Did they wait for older adults to get off and on safely before moving driving away? Did they remind passengers to stay safe, help others, and yield seats?” 0 = “Have not taken public transportation in the past year” 1 = “Always or mostly unfriendly”; 2 = “Sometimes unfriendly”; 3 = “Mostly friendly”; 4 = “Always friendly.” | Questionnaire | Other passengers should exhibit friendly attitudes toward older adults on buses. | When older adults take buses, they often feel that drivers are unfriendly because they require more time to move on and off the bus. This may discourage older adults from taking buses. |
Core | Social Participa tion | Proportion of age-friendly venues | Percentage of venues where older adults gather, such as community activity centers, community care centers, or health centers in the township or city that have adequate lighting, restrooms, and accessible facilities. | Number of venues with adequate lighting, restrooms, and accessible facilities in community activity centers, community care centers, or health centers where older adults gather in the township or city. | Total number of venues where the older adults gather, such as community activity centers, community care centers, or health centers, in the township or city. | Corroborating evidence from surveys acquired by conducting field surveys in the township or city, recording data, and using demographic statistics, health statistics, and government open data websites for verification. | Age-friendly venues (with adequate lighting and accessible facilities) should be created so that older adults have no safety concerns when participating in activities in the venues. | Places where older adults often gather for activities should be designed from the perspective of user safety and provide sufficient lighting, adequate, convenient, and safe restrooms and accessible facilities. Age-friendly venues should be created so that older adults have no safety concerns when participating in activities in the venues. |
Core | Communi cation and Infor mation | Satisfaction with age-friendly counter services at government agencies. | Percentage of survey respondents who are satisfied with age-friendly counter services with designated staff or simplified services provided at government agencies (for example, township or city offices and health centers). | Number of survey respondents who are satisfied or very satisfied with age-friendly counter services or assistance provided by volunteers at government agencies (such as township and city offices and health centers). | Total number of older adults surveyed. Suggested question: “Were you satisfied with the counter services specifically for older adults and the services provided by volunteers to assist older adults when you visited government agencies (for example, township or city offices and health centers)?” 0 = “No designated counter services or volunteer assistance for older adults”; 1 = “Very dissatisfied”; 2 = “Dissatisfied”; 3 = “Satisfied”; 4 = “Very satisfied.” | Questionnaire | To provide older adults with access to special assistance at government agencies and understand how older adults feel about the consulting services offered by government agencies. | Because of declines in comprehension and perception, older adults may require special assistance to obtain information and resources. |
Optional | Outdoor Space and Buildings | Proportion of public buildings that have accessible entrances and exits | Percentage of public buildings, hospitals, public markets, and activity centers in the township or city that have passages with sufficient clearance (for example, ground access, horizontal entrances, wheelchair ramps, automatic doors, and spacious passageways). | Number of public buildings, hospitals, public markets, and activity centers in the township or city that have accessibility features (such as ground access, horizontal entrances, wheelchair ramps, automatic doors, and spacious passageways) | Total number of public buildings, hospitals, public markets, and activity centers in the township or city. | Corroborating evidence from surveys acquired by conducting field surveys in the township or city, recording data, and using demographic statistics, health statistics, and government open data websites for verification. | Buildings with horizontal entrances and wheelchair ramps facilitate access for older people and those with functional disabilities. | An accessible environment removes restrictions to reduce inconvenience for individuals of all ages and enable every person to be universally respected. Public space should enable older adults and people with functional disabilities to enter and exit independently. |
Optional | Transporta tion | Timely removal of road obstacles. | Percentage of road obstacles that can be removed within a reasonable amount of time after being reported by a community leader or resident. | Number of survey respondents who believe that reported road obstructions or street lighting problems (excluding those due to construction work) can be addressed within 4 weeks. Note: The 4-week criterion can be adjusted to local conditions. | Total number of people who took the survey. Suggested question: “How long does it usually take for your community to address the absence of streetlights, broken streetlights, uneven roads, or potholes (excluding problems due to road construction)?” 1 = 1–2 weeks; 2 = 2–4 weeks; 3 = 1–3 months; 4 = 3–6 months; 5 = half a year or more. | Questionnaire | Pedestrian-friendly passages or roads are flat, safe, and free of obstacles and have sufficient lighting for older adults to walk safely. | Because of the gradual deterioration of the visual and auditory functions of older adults, low-lit environments and road obstacles may cause accidents, specifically among some seniors who require mobility assistance. Pedestrian environments must enable older adults to live independently. Friendly, safe, convenient, and flat sidewalks can help older adults live independently. |
Optional | Commu nity and Health Services | Proportion of care services provided at community care centers. | Percentage of community development associations, community care centers, or community leaders’ offices in the township or city that offer contact care services for those at risk of isolation. | Number of community service centers, such as community development associations, community care centers, and community leaders’ offices, in the township or city that regularly (on a fixed schedule) provide care and assistance to isolated or disabled older adults in the community. | Total number of community service organizations, such as community development associations, community care centers, and community leaders’ offices, in the township or city. | Corroborating evidence from surveys acquired by conducting field surveys in the township or city, recording data, and using demographic statistics, health statistics, and government open data websites for verification. | Community development associations, community care centers, and community leaders’ elder-care service networks help older adults leave their houses to participate in community activities. | To prevent social isolation among older adults confined to their homes, community development associations and centers and community leaders’ care service networks can help older adults establish interpersonal relationships in the community, ensure their physical and mental health, and reduce medical and social costs. |
Optional | Communi cation and Infor mation | Visual friendliness satisfaction with government agencies. | Percentage of government agencies (such as township and city offices and health centers) that provide information required by the older adults clearly in large font. | Survey respondents agree or strongly agree that government agencies (such as township and city offices and health centers) provide information required by the older adults clearly in large font (those who do not visit government agencies are excluded). | Total number of older adults surveyed (excluding those who did not visit government agencies). Suggested question: “When you went to a government agency (e.g., township or city offices or health centers) to run errands in the past year, the font on the forms, documents, and indoor signage was legible.” 0 = “Haven’t been to a government agency in the past year”; 1 = “Strongly agree”; 2 = “Agree”; 3 = “Disagree”; 4 = “Strongly disagree”. | Questionnaire | Government agencies should consider older adults’ visual acuity when publishing documents so that older adults can understand them. | Older adults’ preferences and visual acuity should be accounted for to make them feel comfortable and welcome when they acquire information. |
Optional | Communi cation and Infor mation | Amount of information disseminated to older adults through channels. | Percentage of health centers, community care centers, and community leaders’ offices in the township or city that disseminate health and social service information (e.g., mask purchasing and vaccination guidance) through channels such as paper pamphlets and the LINE app. | Number of health centers, community care centers, and community leaders’ offices in the township or city that disseminate health and social service information (e.g., mask purchasing and vaccination guidance) through channels such as paper pamphlets and the LINE app. | Total number of health centers, community care centers, and community leaders’ offices in the township or city. | Corroborating evidence from surveys acquired by conducting field surveys in the township or city, recording data, and using demographic statistics, health statistics, and government open data websites for verification. | Because the channels for older adults to access information vary depending on their area, multiple channels (e.g., broadcasts, telephone, and the Internet) and forms of communication (e.g., oral and written) should be used to help older adults access information. | The Internet has increased access to information and social interaction. However, older adults may fear losing sources of information and being rejected by mainstream society. Quick access to information and communication technology help older adults integrate into society. |
