The dataset is provided by OECD (The Organization for Economic Co-operation and Development) whose mission is to promote policies that will improve the economic and social well-being of people around the world. OECD’s work is based on continued monitoring of events in member countries as well as outside OECD area, and includes regular projections of short and medium-term economic developments. The OECD Secretariat collects and analyses data, after which committees discuss policy regarding this information, the Council makes decisions, and then governments implement recommendations. The OECD Health Datasets offers the most comprehensive source of comparable statistics on health and health systems across OECD countries. It is an essential tool to carry out comparative analyses and draw lessons from international comparisons of diverse health systems. The Eurostat database is the main data source for all European countries. Time series are also completed with national data for selected years.
There is not yet full standardization of the measurement of perceived health status across OECD countries. In Europe, a standard health interview survey instrument has been recommended to measure this variable. The recommendation is described in the publication: “Health Interview Surveys: Towards International Harmonization of Methods and Instruments,” World Health Organization (WHO) Regional Office for Europe, 1996. The question for perceived health status is “How is your health in general?” and answer options are: very good, good, fair, bad or very bad. In dataset it is specified where there is a difference from methodology. At the same time the primary data sources for perceived health status by income level The data sources are generally health or household surveys. Starting from this the perceived health status is the percentage (crude rate) of population of 15 years old or older who report their health to be good or very good (excellent, or all positive response categories), fair (not good, not bad), bad or very bad (all negative response categories). For the perceived health status according to age and gender or according to socioeconomic characteristics (education or income level) is the percentage (crude rate) of population of 15 years old or older who report their health to be good or very good (excellent, or all positive response categories).
Education level is expressed by the highest completed level of education, defined according to the latest International Standard Classification of Education, ISCED-2011. Low education means: early childhood education (ISCED 0), primary education (ISCED 1) and lower secondary education (ISCED 2). The medium education level comprises upper secondary education (ISCED 3), post-secondary non-tertiary education (ISCED 4). High education means: short-cycle tertiary education (ISCED 5), bachelor’s or equivalent level (ISCED 6), master’s or equivalent level (ISCED 7), doctoral or equivalent level (ISCED 8). If the income primary data comes from health survey the individuals’ income will be used to assign them to income quintiles. If data come from household surveys and relate to household income equivalisation of income for persons within households should take place. A common method divides household income by the square root of the household size.
Breaks in the time-related continuity of data on which the calculated indicators values are based are specified in the content of the dataset.
