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 number of daily smokers is defined as the percentage of the population aged 15 years old or over who report that they are daily smokers. International comparability is limited due to the lack of standardization in the measurement of smoking habits in health interview surveys across OECD countries. There is variation in the wording of the question, the response categories and the related administrative methods. The data for the percents of daily smokers are based on national level statistics.
The percent of daily vegetables consumers represents the proportion of the population aged 15 years and above, eating vegetables (excluding potatoes and juice) at least once per day. The percent of daily fruits consumers is proportion of the population aged 15 years and above, eating fruits (excluding juice) at least once per day. The main data sources are national health surveys. A number of European countries have implemented the relevant module recommended in the European Health Interview Survey. Although most countries asked questions of the type “How often do you eat fruits/vegetables”, which provided information on frequency of consumption, some countries (such as Australia, Korea and New Zealand) asked question of the type “How many serves of fruit/vegetables do you usually eat each day”, which provided information on quantity of consumption.
The proportion of overweight or obese population 15 years and above are based on self-reported data (qualitative) and on measured data (quantitative) for body mass index.
Breaks in the time-related continuity of data on which the calculated indicators values are based are specified in the content of dataset. There are also specified the cases were the methodology used for data collection was different or if the values are estimated.
