(2) Caution should be applied when considering that a survey is said to be 'national' as this refers to its intended geographical coverage, but does not mean it is necessarily representative of the national situation, which would depend on any sampling procedures adopted. Note that the size of the prison population surveyed is not available for most of the studies displayed in this table, and sample sizes reflect different proportions of the population in different countries.(3) Results are provided for 4 different sub-groups of population: male remanded, male sentenced, female remanded, female sentenced. Women and men on remand represent a small proportion of the prison population, and thus these groups were over-sampled. Ranges reported here represent the minimum and maximum values obtained across the 4 sub-groups.See also 'General notes for interpreting data' on the <a href="../page055-en.html">Explanatory notes and help</a> page.<em>Sources:</em>For access to sources and bibliographic references, refer to <a href="duptab01-en.html">Table DUP-0</a>.
