Limitations of the unemployment definition

The unemployment rate may be different from the impact of the economy on people. The unemployment figures indicate how many are not working for pay but seeking employment for pay. It is only indirectly connected with the number of people who are actually not working at all or working without pay. Therefore, critics believe that current methods of measuring unemployment are inaccurate in terms of the impact of unemployment on people as these methods do not take into account the 1.5% of the available working population incarcerated in U.S. prisons (who may or may not be working while incarcerated), those who have lost their jobs and have become discouraged over time from actively looking for work, those who are self-employed or wish to become self-employed, such as tradesmen or building contractors or IT consultants, those who have retired before the official retirement age but would still like to work (involuntary early retirees), those on disability pensions who, while not possessing full health, still wish to work in occupations suitable for their medical conditions, those who work for payment for as little as one hour per week but would like to work full-time. These people are "involuntary part-time" workers, those who are underemployed, e.g., a computer programmer who is working in a retail store until he can find a permanent job, involuntary stay-at-home mothers who would prefer to work, and graduate and Professional school students who were unable to find worthwhile jobs after they graduated with their Bachelor's degrees.
On the other hand, the measures of employment and unemployment may be "too high". In some countries, the availability of unemployment benefits can inflate statistics since they give an incentive to register as unemployed. People who do not really seek work may choose to declare themselves unemployed so as to get benefits; people with undeclared paid occupations may try to get unemployment benefits in addition to the money they earn from their work. Conversely, the absence of any tangible benefit for registering as unemployed discourages people from registering.
However, in countries such as the United States, Canada, Mexico, Australia, Japan and the European Union, unemployment is measured using a sample survey (akin to a Gallup poll). According to the BLS, a number of Eastern European nations have instituted labor force surveys as well. The sample survey has its own problems because the total number of workers in the economy is calculated based on a sample rather than a census.
It is possible to be neither employed nor unemployed by ILO definitions, i.e., to be outside of the "labor force." These are people who have no job and are not looking for one. Many of these are going to school or are retired. Family responsibilities keep others out of the labor force. Still others have a physical or mental disability which prevents them from participating in labor force activities.
Typically, employment and the labor force include only work done for monetary gain. Hence, a homemaker is neither part of the labor force nor unemployed. Nor are full-time students nor prisoners considered to be part of the labor force or unemployment. The latter can be important. In 1999, economists Lawrence F. Katz and Alan B. Krueger estimated that increased incarceration lowered measured unemployment in the United States by 0.17% between 1985 and the late 1990s. In particular, as of 2005, roughly 0.7% of the US population is incarcerated (1.5% of the available working population).
Children, the elderly, and some individuals with disabilities are typically not counted as part of the labor force in and are correspondingly not included in the unemployment statistics. However, some elderly and many disabled individuals are active in the labor market.
In the early stages of an economic boom, unemployment often rises. This is because people join the labor market (give up studying, start a job hunt, etc.) because of the improving job market, but until they have actually found a position they are counted as unemployed. Similarly, during a recession, the increase in the unemployment rate is moderated by people leaving the labor force or being otherwise discounted from the labor force, such as with the self-employed.
For the fourth quarter of 2004, according to OECD, (source Employment Outlook 2005 ISBN 92-64-01045-9), normalized unemployment for men aged 25 to 54 was 4.6% in the USA and 7.4% in France. At the same time and for the same population the employment rate (number of workers divided by population) was 86.3% in the U.S. and 86.7% in France.
This example shows that the unemployment rate is 60% higher in France than in the USA, yet more people in this demographic are working in France than in the USA, which is counterintuitive if it is expected that the unemployment rate reflects the health of the labor market.
Due to these deficiencies, many labor market economists prefer to look at a range of economic statistics such as labor market participation rate, the percentage of people aged between 15 and 64 who are currently employed or searching for employment, the total number of full-time jobs in an economy, the number of people seeking work as a raw number and not a percentage, and the total number of person-hours worked in a month compared to the total number of person-hours people would like to work. In particular the NBER does not use the unemployment rate but prefer various employment rates to date recessions.
