The unemployment rate announced by United States Department of Labor does not include those too discouraged to look for work any longer or those part-time workers who are working fewer hours than they would like.
 By adding these two groups to the unemployment rate, the rate becomes the effective unemployment rate.
Full employment, in macroeconomics, is the level of employment rates where there is no cyclical or 。deficient-demand unemployment.
 It is defined by the majority of mainstream economists as being an acceptable level of unemployment somewhere above 0%.
 The discrepancy from 0% arises due to non-cyclical types of unemployment, such as frictional unemployment (there will always be people who have quit or have lost a seasonal job and are in the process of getting a new job) and structural unemployment (mismatch between worker skills and job requirements).
 Unemployment above 0% is seen as necessary to control inflation in capitalist economies, to keep inflation from "accelerating", i.e., from rising from year to year.
 This view is based on a theory centering on the concept of the Non-Accelerating Inflation Rate of Unemployment (NAIRU); in the current era, the majority of mainstream economists mean NAIRU when speaking of "full" employment.
 The NAIRU has also been described by Milton Friedman, among others, as the "natural" rate of unemployment.
 Having many names, it has also been called the structural unemployment rate.
The list of Canadian provinces by unemployment rate are statistics that directly refer to the nation's seasonally adjusted unemployment rate.
 Below is a comparison of the seasonally adjusted unemployment rates by province/territory, sortable by name or unemployment rate.

 "Not seasonally adjusted" data reflects the actual current unemployment rate, while "seasonally adjusted" data removes the seasonal component from the information.

Youth unemployment in the United Kingdom is the level of unemployment among young people, typically defined as those aged 18–25.
 A related concept is graduate unemployment which is the level of unemployment among university graduates.
 Statistics for June 2010 show that there are 926,000 young people under the age of 25 who are unemployed which equates to an unemployment rate of 19.6% among young people.
 This is the highest youth unemployment rate in 17 years.
 In November 2011 youth unemployment hit 1.02 million, but had fallen to 767,000 by August 2014.
 The high levels of youth unemployment in the United Kingdom have led some politicians and media commentators to talk of a "lost generation".
Unemployment in Poland appeared in the 19th century, during the process of industrialization, and was particularly severe during the Great Depression.
 During communist rule officially Poland had close to full employment although hidden unemployment existed.
 After Poland's transition to a market economy the unemployment rate sharply increased, peaking at above 16% in 1993, then dropped afterwards, but remained well above pre-1993 levels.
 Another period of high unemployment occurred in the early 2000s when the rate reached 20%.
 As Poland entered European Union (EU) in 2004 and its job market, mass emigration due to unemployment took place lowering the figure.
 Since then the rate had fallen until the onset of the 2008 Great Recession.
 Recent years have seen an increase in the unemployment rate from below 8% to above 10% (Eurostat) or from below 10% to 13% (GUS).
 The rate began dropping again in late 2013.
 Polish government (GUS) reported 9.6% registered unemployment in November 2015, while European Union's Eurostat gave 7.2%.
 According to Eurostat data, since 2008, unemployment in Poland has been constantly below the EU average.
 Significant regional differences in the unemployment rate exist across Poland.
The unemployment rate is a measure of the prevalence of unemployment and it is calculated as a percentage by dividing the number of unemployed individuals by all individuals currently in the labor force.
 During periods of recession, an economy usually experiences a relatively high unemployment rate.
 According to International Labour Organization report, more than 200 million people globally or 6% of the world's workforce were without a job in 2012.
The monetary policy reaction function (MPRF) is the upward-sloping relationship between the inflation rate and the unemployment rate.
 When the inflation rate rises, a central bank wishing to fight inflation will raise interest rates to reduce output and thus increase the unemployment rate.
