Principles of Economics21.1 How the Unemployment Rate is Defined and Computed

### Learning Objectives

By the end of this section, you will be able to:

• Calculate the labor force percentage and the unemployment rate
• Explain hidden unemployment and what it means to be in or out of the labor force
• Evaluate the collection and interpretation of unemployment data

Unemployment is typically described in newspaper or television reports as a percentage or a rate. A recent report might have said, for example, from August 2009 to November 2009, the U.S. unemployment rate rose from 9.7% to 10.0%, but by June 2010, it had fallen to 9.5%. At a glance, the changes between the percentages may seem small. But remember that the U.S. economy has about 155 million adults who either have jobs or are looking for them. A rise or fall of just 0.1% in the unemployment rate of 155 million potential workers translates into 155,000 people, which is roughly the total population of a city like Syracuse, New York, Brownsville, Texas, or Pasadena, California. Large rises in the unemployment rate mean large numbers of job losses. In November 2009, at the peak of the recession, about 15 million people were out of work. Even with the unemployment rate now at 5.5% as of February 2015, about 8 million people total are out of work.

The Bureau of Labor Statistics tracks and reports all data related to unemployment.

### Whoâ€™s In or Out of the Labor Force?

Should everyone without a job be counted as unemployed? Of course not. Children, for example, should not be counted as unemployed. Surely, the retired should not be counted as unemployed. Many full-time college students have only a part-time job, or no job at all, but it seems inappropriate to count them as suffering the pains of unemployment. Some people are not working because they are rearing children, ill, on vacation, or on parental leave.

The point is that the adult population is not just divided into employed and unemployed. A third group exists: people who do not have a job, and for some reasonâ€”retirement, looking after children, taking a voluntary break before a new jobâ€”are not interested in having a job, either. It also includes those who do want a job but have quit looking, often due to being discouraged by their inability to find suitable employment. Economists refer to this third group of those who are not working and not looking for work as out of the labor force or not in the labor force.

The U.S. unemployment rate, which is based on a monthly survey carried out by the U.S. Bureau of the Census, asks a series of questions to divide up the adult population into employed, unemployed, or not in the labor force. To be classified as unemployed, a person must be without a job, currently available to work, and actively looking for work in the previous four weeks. Thus, a person who does not have a job but who is not currently available to work or has not actively looked for work in the last four weeks is counted as out of the labor force.

Employed: currently working for pay

Unemployed: Out of work and actively looking for a job

Out of the labor force: Out of paid work and not actively looking for a job

Labor force: the number of employed plus the unemployed

### Calculating the Unemployment Rate

Figure 21.2 shows the three-way division of the over-16 adult population. In February 2015, about 62.8% of the adult population was "in the labor force"; that is, people are either employed or without a job but looking for work. Those in the labor force can be divided into the employed and the unemployed. These values are also shown in Table 21.1. The unemployment rate is not the percentage of the total adult population without jobs, but rather the percentage of adults who are in the labor force but who do not have jobs:

Figure 21.2 Employed, Unemployed, and Out of the Labor Force Distribution of Adult Population (age 16 and older), February 2015 The total adult, working-age population in February 2015 was 249.9 million. Out of this total population, 148.3 were classified as employed, and 8.7 million were classified as unemployed. The remaining 92.9 were classified as out of the labor force. As you will learn, however, this seemingly simple chart does not tell the whole story.
 Total adult population over the age of 16 249.9 million In the labor force 157 million (62.8%) Employed 148.3 million Unemployed 8.7 million Out of the labor force 92.9 million (37.2%)
Table 21.1 U.S. Employment and Unemployment, February 2015 (Source: http://www.bls.gov/news.release/empsit.t01.htm)

In this example, the unemployment rate can be calculated as 8.7 million unemployed people divided by 157 million people in the labor force, which works out to a 5.5% rate of unemployment. The following Work It Out feature will walk you through the steps of this calculation.

### Work It Out

#### Calculating Labor Force Percentages

So how do economists arrive at the percentages in and out of the labor force and the unemployment rate? We will use the values in Table 21.1 to illustrate the steps.

To determine the percentage in the labor force:

Step 1. Divide the number of people in the labor force (157 million) by the total adult (working-age) population (249.9 million).

Step 2. Multiply by 100 to obtain the percentage.

To determine the percentage out of the labor force:

Step 1. Divide the number of people out the labor force (92.9 million) by the total adult (working-age) population (249.9 million).

Step 2. Multiply by 100 to obtain the percentage.

To determine the unemployment rate:

Step 1. Divide the number of unemployed people (8.7 million) by the total labor force (157 million).

Step 2. Multiply by 100 to obtain the rate.

### Hidden Unemployment

Even with the â€śout of the labor forceâ€ť category, there are still some people that are mislabeled in the categorization of employed, unemployed, or out of the labor force. There are some people who have only part time or temporary jobs and who are looking for full time and permanent employment that are counted as employed, though they are not employed in the way they would like or need to be. Additionally, there are individuals who are underemployed. This includes those that are trained or skilled for one type or level of work who are working in a lower paying job or one that does not utilize their skills. For example, an individual with a college degree in finance who is working as a sales clerk would be considered underemployed. They are, however, also counted in the employed group. All of these individuals fall under the umbrella of the term â€śhidden unemployment.â€ť Discouraged workers, those who have stopped looking for employment and, hence, are no longer counted in the unemployed also fall into this group

### Labor Force Participation Rate

Another important statistic is the labor force participation rate. This is the percentage of adults in an economy who are either employed or who are unemployed and looking for a job. So, using the data in Figure 21.2 and Table 21.1, those included in this calculation would be the 157 million individuals in the labor force. The rate is calculated by taking the number of people in the labor force, that is, the number employed and the number unemployed, divided by the total adult population and multiplying by 100 to get the percentage. For the data from February 2015, the labor force participation rate is 62.8%. Historically, the civilian labor force participation rate in the United States climbed beginning in the 1960s as women increasingly entered the workforce, and it peaked at around 68% in late 1999 to early 2000. Since then, the labor force participation rate has steadily declined.

### The Establishment Payroll Survey

When the unemployment report comes out each month, the Bureau of Labor Statistics (BLS) also reports on the number of jobs createdâ€”which comes from the establishment payroll survey. The payroll survey is based on a survey of about 140,000 businesses and government agencies throughout the United States. It generates payroll employment estimates by the following criteria: all employees, average weekly hours worked, and average hourly, weekly, and overtime earnings. One of the criticisms of this survey is that it does not count the self-employed. It also does not make a distinction between new, minimum wage, part time or temporary jobs and full time jobs with â€śdecentâ€ť pay.

### How Is the U.S. Unemployment Data Collected?

The unemployment rate announced by the U.S. Bureau of Labor Statistics each month is based on the Current Population Survey (CPS), which has been carried out every month since 1940. Great care is taken to make this survey representative of the country as a whole. The country is first divided into 3,137 areas. The U.S. Bureau of the Census then selects 729 of these areas to survey. The 729 areas are then divided into districts of about 300 households each, and each district is divided into clusters of about four dwelling units. Every month, Census Bureau employees call about 15,000 of the four-household clusters, for a total of 60,000 households. Households are interviewed for four consecutive months, then rotated out of the survey for eight months, and then interviewed again for the same four months the following year, before leaving the sample permanently.

Based on this survey, unemployment rates are calculated by state, industry, urban and rural areas, gender, age, race or ethnicity, and level of education. A wide variety of other information is available, too. For example, how long have people been unemployed? Did they become unemployed because they quit, or were laid off, or their employer went out of business? Is the unemployed person the only wage earner in the family? The Current Population Survey is a treasure trove of information about employment and unemployment. If you are wondering what the difference is between the CPS and EPS, read the following Clear it Up feature.

### Clear It Up

#### What is the difference between CPS and EPS?

The Current Population Survey (CPS) conducted by the United States Census Bureau measures the percentage of the labor force that is unemployed. The establishment payroll survey (EPS) by the Bureau of Labor Statistics is a payroll survey that measures the net change in jobs created for the month.

### Criticisms of Measuring Unemployment

There are always complications in measuring the number of unemployed. For example, what about people who do not have jobs and would be available to work, but have gotten discouraged at the lack of available jobs in their area and stopped looking? Such people, and their families, may be suffering the pains of unemployment. But the survey counts them as out of the labor force because they are not actively looking for work. Other people may tell the Census Bureau that they are ready to work and looking for a job but, truly, they are not that eager to work and are not looking very hard at all. They are counted as unemployed, although they might more accurately be classified as out of the labor force. Still other people may have a job, perhaps doing something like yard work, child care, or cleaning houses, but are not reporting the income earned to the tax authorities. They may report being unemployed, when they actually are working.

Although the unemployment rate gets most of the public and media attention, economic researchers at the Bureau of Labor Statistics publish a wide array of surveys and reports that try to measure these kinds of issues and to develop a more nuanced and complete view of the labor market. It is not exactly a hot news flash that economic statistics are imperfect. Even imperfect measures like the unemployment rate, however, can still be quite informative, when interpreted knowledgeably and sensibly.
