General population surveys — an overview of the data

Introduction

The general population surveys tables and graphics in the Statistical bulletin are organised by age group (all adults — 15–64 years, young adults — 15–34 years and youth-15–24 year olds), gender, type of prevalence (lifetime prevalence, last year prevalence and last month prevalence) and in case of graphics, also according to drug of use (cannabis, amphetamines, ecstasy, and cocaine).

Table GPS-121 provides detailed methodological information on the general population surveys, and Table GPS-0 provides the bibliographic references for additional information.

Tables GPS-1 to GPS-9 are organised according to age group and type of prevalence. Tables GPS-1 to GPS-6 are based on latest available data in each country, while GPS-7 to GPS-9 list data from all available surveys. Tables GPS-4 to GPS-6 have data based on the last survey available in each country broken down by gender.

The table below summarizes the data tables: the first table in each cell has only the latest data available, while the second one has all available data.

Age group/type of prevalence	Lifetime prevalence	Last 12 months prevalence	Last 30 days prevalence
15–64 (‘all adults’)	Table GPS-1 part (ii) and Table GPS-7 part (ii)	Table GPS-2 part (i) and Table GPS-8 part (i)	Table GPS-3 part (i) and Table GPS-9 part (i)
15–34 (‘young adults’)	Table GPS-1 part (iii) and Table GPS-7 part (iii)	Table GPS-2 part (ii) and Table GPS-8 part (ii)	Table GPS-3 part (ii) and Table GPS-9 part (ii)
15–24 ('youth')	Table GPS-1 part (iv) and Table GPS-7 part (iv)	Table GPS-2 part (iii) and Table GPS-8 part (iii)	Table GPS-3 part (iii) and Table GPS-9 part (iii)

Table GPS-10 provides data focused on indicators of more intensive cannabis use — last month prevalence of use and prevalence of daily or almost daily use (20 days or more/30) based on the most recent available data (part i), for the participating countries in the 2007 field trial (part (ii)), frequency of use in the past month (part (iii)), where data was available in the 2004 field trial and combined sources (part (iv)).

Figure GPS-17, GPS-18 and GPS-23 show comparative data for several drugs together, while other graphics are organised by drug type.

Cannabis-use prevalence is shown in Figures GPS-1, GPS-2, GPS-3, GPS-4, GPS-7, GPS-10 and GPS-12. Amphetamine use is shown in Figures GPS-5, GPS-6, GPS-8 and GPS-22. Ecstasy use data is displayed in Figures GPS-9, GPS-11 and GPS-21. Cocaine use prevalence can be found in Figures GPS-13, GPS-14, GPS-15, GPS-16 and GPS-20. Information on trends can be found in Figures GPS-4, GPS-8, GPS-10, GPS-14, GPS-21 and GPS-20.
