Unemployment rate is the ratio of unemployed people to the labour force.
Unemployment is useful and relevant to measuring sustainable development, especially if uniformly measured over time, and considered with other socioeconomic indicators. It should be noted, however, that it is common to find people working full-time but remaining poor due to the particular social conditions and type of industrial relations prevalent in their country, industry, or occupation. This indicator is linked to other socioeconomic indicators such as poverty measures and adult literacy. Some particular groups, such as the armed forces or other populations living in institutions, nomadic people, etc. may be excluded. In countries where compulsory schooling and legislation on the minimum age for admission to employment have broad coverage and are widely respected, the age specified in these regulations may be used as a basis for determining an appropriate minimum age limit for measuring the economically active population.
