Price data may differ from data as reported due to conversions made by UNODC. Prices are collected in local currency but are presented here in US dollars for the purposes of comparability among countries. The conversion into US dollars is based on official UN rates. However, comparisons of prices from different years need to be made with caution as they are influenced by changes in the exchange rates and may not necessarily reflect changes in the local markets. While the same price can be meaningfully expressed in various units (e.g. per kilogram, per gram), the purchase unit as presented here (and as requested in the ARQ) is intended to approximate, to the extent allowed by the availability of information, the level at which transactions occur; thus a retail price, for example, would normally be expressed per gram even if reported per kilogram. On the other hand, the reporting unit is not converted if it is believed to represent the actual transaction level, except that non-standard units are converted when possible to the nearest available metric unit.

The indicator measures the share of the population aged 16 and over reporting unmet needs for medical care due to one of the following reasons: ‘Financial reasons’, ‘Waiting list’ and ‘Too far to travel’ (all three categories are cumulated). Self-reported unmet needs concern a person’s own assessment of whether he or she needed medical examination or treatment (dental care excluded), but did not have it or did not seek it. The data stem from the EU Statistics on Income and Living Conditions (EU SILC). Note on the interpretation: The indicator is derived from self-reported data so it is, to a certain extent, affected by respondents’ subjective perception as well as by their social and cultural background. Another factor playing a role is the different organisation of health care services, be that nationally or locally. All these factors should be taken into account when analysing the data and interpreting the results.
