908 ITU‐T's Technical Reports and Specifications End‐of‐life care Ranking of countries according to their provision of end‐of‐life care. The Quality of Death Index scores countries across four categories: Basic End‐of‐Life Healthcare Environment; Availability of End‐of‐Life Care; Cost of End of‐Life Care; and Quality of End‐of‐Life Care. These indicator categories are composed of 27 variables, including quantitative, qualitative and \"status\" (whether or not something is the case) data. The indicator data are aggregated, normalized, and weighted to create the total index score. Entrepreneurial environment Measurement of the entrepreneurial attitudes, entrepreneurial activity and entrepreneurial aspirations in a country. The Global Entrepreneurship Index integrates 31 variables, including quantitative and qualitative measures and individual‐level data. Financial and business services employment Proportion of employees working in businesses located within a city in the financial and business services sectors to the total employed workforce in the city. Where industry data were disaggregated, the equivalents of \"finance and insurance\" and \"real estate and rental and leasing\" were included in financial services; and the equivalents of \"professional and technical services\" and \"management of companies and enterprises\" were included in business services. Flexibility of visa travel Ranking based on the number of visa waivers available for tourist or business visits and the length of time for which the visa waiver is granted. Ranking is based on the number of those countries that can stay for at least 90 days, excluding those countries whose residents can enter only without a visa if they have a biometric, diplomatic or official passport. Foreign embassies or consulates Number of countries that are represented by a consulate or embassy in each city. Green space as a percent of city area Proportion of a city's land area designated as recreational and green spaces to the total land area. Excludes undeveloped rugged terrain or wilderness that is either not easily accessible or not conducive to use as public open space. Health system performance Measurement of a country's health system performance made by comparing healthy life expectancy with health care expenditures per capita in that country, adjusted for average years of education (years of education is strongly associated with the health of populations in both developed and developing countries). Methodology adapted from the 2001 report \"Comparative efficiency of national health systems: cross‐national econometric analysis\". Hospitals Ratio of all hospitals within each city accessible to international visitors to every 100,000 members of the total population. Hotel rooms Count of all hotel rooms within each city. Housing Measure of availability, diversity, cost and quality of housing, household appliances and furniture, as well as household maintenance and repair. Incoming/outgoing passenger flows Total number of incoming and outgoing passengers, including originating, terminating, transfer and transit passengers in each of the major airports servicing a city. Transfer and transit passengers are counted twice. Transit passengers are defined as air travellers coming from different ports of departure who stay at the airport for brief periods, usually one hour, with the intention of proceeding to their first port of destination (includes sea, air and other transport hubs).
