The unemployed are people of working age who are without work, are available for work, and have taken specific steps to find work. The uniform application of this definition results in estimates of unemployment rates that are more internationally comparable than estimates based on national definitions of unemployment. Unemployment rates are shown for two age groups: people aged 15 to 24 (those just entering the labour market following education); and people aged 25 and over. This indicator is measured in numbers of unemployed people as a percentage of the labour force and it is seasonally adjusted. The labour force is defined as the total number of unemployed people plus those in civilian employment. Data are based on labour force surveys (LFS).  For European Union countries where monthly LFS information is not available, the monthly unemployed figures are estimated by Eurostat.
