In 2017, the broadest measure of labor underutilization, designated U-6 (which includes the unemployed, workers employed part time for economic reasons, and those marginally attached to the labor force), was 7.8 percent in South Carolina, not significantly different from the 8.5-percent rate for the nation, the U.S. Bureau of Labor Statistics reported today. Regional Commissioner Janet S. Rankin noted that among the six alternative measures of labor underutilization in South Carolina, only the U-6 rate was significantly different from a year ago. Nationally, all six measures declined significantly over the year. (See table 1.)

The official concept of unemployment, U-3 in the U-1 to U-6 range of measures, includes all jobless persons who are available to take a job and have actively sought work in the past 4 weeks. In South Carolina, 4.4 percent of the labor force was unemployed as measured by U-3 in 2017, not measurably different than the 4.4-percent rate for the nation. (See chart 1.) (The official measure of unemployment in the states is derived using a statistical model that incorporates data from the Current Population Survey [CPS] and other sources, and this model-based estimate can differ from the direct CPS estimate discussed here.)

South Carolina had 100,000 unemployed residents in 2017 according to the CPS. In addition, there were 54,800 workers who were employed part time for economic reasons (also known as involuntary part time). These individuals were working part time because of slack work or business conditions, or because they were unable to find a full-time job. (See chart 2.) Nationwide, there were 5.3 million individuals working part time for economic reasons in 2017.

In 2017, the number of individuals considered to be marginally attached to the labor force in South Carolina was 24,900. People marginally attached to the labor force are not working but indicate that they would like to work, are available to work, and have looked for work at some time during the past 12 months even though they had not searched for work in the 4 weeks preceding the survey. In the United States, the number marginally attached totaled 1.6 million in 2017.

Discouraged workers, a subset of the marginally attached, are persons who are not currently looking for work because they believe no jobs are available for them. In 2017, there were 7,000 discouraged workers in South Carolina, accounting for about 28 percent of all marginally attached workers in the state. The U-4 measure, which adds discouraged workers to the number of the unemployed (expressed as a percentage of the labor force plus the number of discouraged workers), was 4.7 percent in South Carolina, not significantly different from the national rate of 4.6 percent.

State comparisons

In 2017, 10 states had rates lower than those of the U.S. for all six measures, while 4 states and the District of Columbia had rates higher than those of the U.S. for all six measures. (See table 2.) The difference between U-3 and U-4 reflects the degree of would-be job-seeker discouragement. No state had a noteworthy difference between these two measures. Nationally, the difference between U-3 and U-4 was +0.2 percentage point for 2017. The U-5 rate includes all persons who are marginally attached to the labor force and U-6 adds those who are involuntary part-time workers. The larger (smaller) the difference between U-5 and U-6, the higher (lower) the incidence of this form of “underemployment.” All states and the District of Columbia had differences between their U-5 and U-6 rates. Nevada had the largest gap (+4.5 percentage points) and South Dakota had the smallest gap (+2.0 points). At the national level, the difference between U-5 and U-6 was +3.2 percentage points for 2017.

Relative to 2016, three states (California, Tennessee, and Wisconsin) experienced decreases in all six measures of labor underutilization. For each measure, rates declined over the year for at least 7 states (U-2) and as many as 23 states (U-6). Only three states had over-the-year increases in any of the measures: Alaska (+1.4 percentage points for U-5), Delaware (+0.9 point for U-5 and +1.4 points for U-6), and South Dakota (+0.7 point for U-2 and +1.0 point for U-5).

Many states with extreme measures, either low or high, maintained their general place in the rankings of alternative measures over the year. Hawaii, Nebraska, New Hampshire, North Dakota, and Vermont had rates among the 10 lowest for each measure in 2016 and 2017. Similarly, Alaska, Louisiana, New Mexico, and West Virginia had rates among the 10 highest for each measure in both years.

Technical Note

The U.S. Bureau of Labor Statistics (BLS) produces six measures of labor underutilization based on Current Population Survey (CPS) data. Monthly, the BLS publishes these six measures for the United States in the Employment Situation news release. (See www.bls.gov/news.release/empsit.t15.htm.) State estimates, presented as 4-quarter averages, are provided each quarter on the BLS website. (For the most recent data see www.bls.gov/lau/stalt.htm.)

The official concept of unemployment (as measured in the CPS) is equivalent to the U-3 in the U-1 to U-6 range of measures. The other measures are provided to data users and analysts who want more narrowly (U-1 and U-2) or broadly (U-4 through U-6) defined measures.

The unemployment rates (U-3) in this release are derived directly from the CPS, because this is the only source of data for the various components of the alternative measures. As a result, these U-3 measures may differ from the official state annual average unemployment rates. The latter are estimates developed from statistical models that greatly improve the reliability of the top-side labor force and unemployment estimates. Those models, developed by the Local Area Unemployment Statistics (LAUS) program, incorporate CPS estimates, as well as input data from other sources. The model-based estimates are accessible through the LAUS home page at www.bls.gov/lau/home.htm.

Footnotes: (1) The U-3 rates presented are unofficial state estimates derived from the Current Population Survey (CPS). The official measure is a model-based estimate available through the Local Area Unemployment Statistics (LAUS) program at www.bls.gov/lau/data. (2) Persons marginally attached to the labor force are those who currently are neither working nor looking for work but indicate that they want and are available for a job and have looked for work sometime in the past 12 months. Discouraged workers, a subset of the marginally attached, have given a job-market related reason for not currently looking for work. Persons employed part time for economic reasons are those who want and are available for full-time work but have had to settle for a part-time schedule.
Note: An asterisk indicates that the over-the-year change is statistically different at the 90-percent confidence level.
