Methods of calculation and presentation of unemployment rate vary from country to country. Some countries count insured unemployed only, some count those in receipt of welfare benefit only, some count the disabled and other permanently unemployable people, some countries count those who choose (and are financially able) not to work, supported by their spouses and caring for a family, some count students at college and so on.
For purposes of comparison, harmonized values are published by International Labour Organization (ILO) and by OECD. The ILO harmonized unemployment rate refers to those who are currently not working but are willing and able to work for pay, currently available to work, and have actively searched for work. The OECD harmonized unemployment rate gives the number of unemployed persons as a percentage of the labour force.
