Population with access to essential drugs 2000. The data on access to essential drugs are based on statistical estimates received from World Health Organization (WHO) country and regional offices and regional advisers and through the World Drug Situation Survey carried out in 1998-99. These estimates represent the best information available to the WHO Department of Essential Drugs and Medicines Policy to date and are currently being validated by WHO member states. The department assigns the estimates to four groupings: very low access (0-49%), low access (50-79%), medium access (80-94%) and good access (95-100%). These groupings, used here in presenting the data, are often employed by the WHO in interpreting the data, as the actual estimates may suggest a higher level of accuracy than the data afford. b.

Maternal mortality reported per 100,000 births 1985-1999. The maternal mortality data are those reported by national authorities. UNICEF and the World Health Organization periodically evaluate these data and make adjustments to account for the well-documented problems of under-reporting and misclassification of maternal deaths and to develop estimates for countries with no data (for details on the most recent estimates see Hill, AbouZahr and Wardlaw 2001). Data refer to the most recent year available during the period specified.

Percentage of total population who have a BMI (body mass index) greater than 30 Kg/sq.meters (Data for Australia, Austria and Portugal is from 2002. All other data is from 2003). Obesity rates are defined as the percentage of the population with a Body Mass Index (BMI) over 30. The BMI is a single number that evaluates an individual's weight status in relation to height (weight/height2, with weight in kilograms and height in metres). For Australia, the United Kingdom and the United States, figures are based on health examinations, rather than self-reported information. Obesity estimates derived from health examinations are generally higher and more reliable than those coming from self-reports, because they preclude any misreporting of people's height and weight. However, health examinations are only conducted regularly in a few countries (OECD).
