(NOTE: Monthly national Mass Layoffs data for April through September 2010 have been found 

to contain errors in each of the 6 seasonally adjusted series appearing in the charts, the text, and 

tables 1 and 3. Not seasonally adjusted data and regional office news releases are not affected. 

The corrected seasonally adjusted estimates for April through September are located in the Mass 

Layoffs database at www.bls.gov/mls/#data.)

MASS LAYOFFS – MAY 2010 

Employers took 1,412 mass layoff actions in May that resulted in the separation of 135,789 workers, 

seasonally adjusted, as measured by new filings for unemployment insurance benefits during the month, 

the U.S. Bureau of Labor Statistics reported today. Each action involved at least 50 persons from a single employer. The number of mass layoff events in May decreased by 444 from the prior month, and the 

number of associated initial claims decreased by 65,081. In May, 266 mass layoff events were reported 

in the manufacturing sector, seasonally adjusted, resulting in 22,577 initial claims. Both figures declined 

over the month to their lowest levels in program history. (Data begin in 1995. See table 1.)

During the 30 months from December 2007 through May 2010, the total number of mass layoff events 

(seasonally adjusted) was 60,205, and the associated number of initial claims was 6,068,342. (December 

2007 was the start of a recession as designated by the National Bureau of Economic Research.) 

The national unemployment rate was 9.7 percent in May 2010, seasonally adjusted, down from 9.9 percent the prior month and up from 9.4 percent a year earlier. In May, total nonfarm payroll employment 

grew by 431,000 over the month, reflecting the hiring of 411,000 temporary employees to work on Census 2010, but down by 585,000 from a year earlier.

Industry Initial claims May peak

Industry Distribution (Not Seasonally Adjusted) 

The number of mass layoff events in May was 1,354 on a not seasonally adjusted basis; the number of 

associated initial claims was 123,333. (See table 2.) Over the year, the number of average weekly mass 

layoff events decreased by 209, and associated average weekly initial claims decreased by 27,092. Fifteen of the 19 major industry sectors in the private economy reported over-the-year decreases in average 

weekly initial claims, led by manufacturing. (Average weekly analysis mitigates the effect of differing 

lengths of months. See the Technical Note.) Both average weekly events and initial claimants reached 

their highest May levels in program history in 2009. 

The manufacturing sector accounted for 16 percent of all mass layoff events and initial claims filed in 

May 2010. A year earlier, manufacturing made up 37 percent of events and 43 percent of initial claims. 

Within manufacturing, the number of claimants in May 2010 was greatest in food and transportation 

equipment. (See table 3.) All 21 manufacturing subsectors experienced over-the-year decreases in 

average weekly initial claims, led by transportation equipment. 

The six-digit industry with the largest number of initial claims in May 2010 was food service contractors. (See table A.) Of the 10 detailed industries with the largest number of mass layoff initial claims, 

teleproduction and postproduction services, elementary and secondary schools, junior colleges, and 

colleges and universities reached program highs for the month of May. This table includes both publicly- and privately-owned entities. 

Geographic Distribution (Not Seasonally Adjusted) 

All four regions and all nine divisions experienced over-the-year decreases in average weekly initial 

claims due to mass layoffs in May. Among the four census regions, the Midwest and South registered 

the largest over-the-year declines in average weekly initial claims. Of the nine geographic divisions, the 

East North Central and the Middle Atlantic had the largest over-the-year declines. 
- 3 - 

California recorded the highest number of initial claims in May, followed by Texas, Florida, and Illinois. 

(See table 6.) Forty-four states experienced over-the-year decreases in average weekly initial claims, led 

by Michigan, Pennsylvania, Ohio, and Illinois. 

Note 

The monthly data series in this release cover mass layoffs of 50 or more workers beginning in a given 

month, regardless of the duration of the layoffs. For private nonfarm establishments, information on the 

length of the layoff is obtained later and issued in a quarterly release that reports on mass layoffs lasting 

more than 30 days (referred to as "extended mass layoffs"). The quarterly release provides more information on the industry classification and location of the establishment and on the demographics of 

the laid-off workers. Because monthly figures include short-term layoffs of 30 days or less, the sum of 

the figures for the 3 months in a quarter will be higher than the quarterly figure for mass layoffs of more 

than 30 days. (See table 4.) See the Technical Note for more detailed definitions. 

____________ 

The Mass Layoffs in June 2010 news release is scheduled to be released on Friday, July 23, 2010, 

at 10:00 a.m. (EDT). 
Technical Note 

The Mass Layoff Statistics (MLS) program is a federalstate program that uses a standardized automated approach to 

identifying, describing, and tracking the effects of major job 

cutbacks, using data from each state's unemployment 

insurance database. Each month, states report on employers 

which have at least 50 initial claims filed against them during 

a consecutive 5-week period. These employers then are 

contacted by the state agency to determine whether these 

separations lasted 31 days or longer, and, if so, other 

information concerning the layoff is collected. States report 

on layoffs lasting more than 1 month on a quarterly basis. 

A given month contains an aggregation of the weekly 

unemployment insurance claims filings for the Sunday 

through Saturday weeks in that month. All weeks are 

included for the particular month, except if the first day of the 

month falls on Saturday. In this case, the week is included in 

the prior month's tabulations. This means that some months 

will contain 4 weeks and others, 5 weeks. The number of 

weeks in a given month may be different from year to year, 

and the number of weeks in a year may vary. Therefore, 

analysis of over-the-month and over-the-year change in not 

seasonally adjusted series should take this calendar effect into 

consideration. 

The MLS program resumed operations in April 1995 

after it had been terminated in November 1992 due to lack of 

funding. Prior to April 1995, monthly layoff statistics were 

not available. 

Information in this release will be made available to 

sensory impaired individuals upon request. Voice phone: 

(202) 691-5200; Federal Relay Service: (800) 877-8339 

Definitions 

Employer. Employers in the MLS program include 

those covered by state unemployment insurance laws. 

Information on employers is obtained from the Quarterly 

Census of Employment and Wages (QCEW) program, which 

is administered by the Bureau of Labor Statistics (BLS). 

Industry. Employers are classified according to the 

2007 version of the North American Industry Classification 

System (NAICS). For temporary help and professional 

employer organization industries, monthly MLS-related 

statistics generally reflect layoffs related to underlying client 

companies in other industries. An individual layoff action at 

a client company can be small, but when initial claimants 

associated with many such layoffs are assigned to a temporary help or professional employer organization firm, a 

mass layoff event may trigger. 

Initial claimant. A person who files any notice of unemployment to initiate a request either for a determination of 

entitlement to and eligibility for compensation, or for a 

subsequent period of unemployment within a benefit year or 

period of eligibility. 

Mass layoff event. Fifty or more initial claims for 

unemployment insurance benefits filed against an employer 

during a 5-week period, regardless of duration. 

Seasonal adjustment 

Effective with the release of data for January 2005, BLS 

began publishing six seasonally adjusted monthly MLS 

series. The six series are the numbers of mass layoff events 

and mass layoff initial claims for the total, private nonfarm, 

and manufacturing sectors. 

Seasonal adjustment is the process of estimating and 

removing the effect on time series data of regularly recurring 

seasonal events such as changes in the weather, holidays, and 

the beginning and ending of the school year. The use of 

seasonal adjustment makes it easier to observe fundamental 

changes in time series, particularly those associated with 

general economic expansions and contractions. 

The MLS data are seasonally adjusted using the X-12-

ARIMA seasonal adjustment method on a concurrent basis. 

Concurrent seasonal adjustment uses all available monthly 

estimates, including those for the current month, in developing seasonal adjustment factors. Revisions to the most 

recent 5 years of seasonally adjusted data will be made once a 

year with the issuance of December data. Before the data are 

seasonally adjusted, prior adjustments are made to the 

original data to adjust them for differences in the number of 

weeks used to calculate the monthly data. Because weekly 

unemployment insurance claims are aggregated to form 

monthly data, a particular month's value could be calculated 

with 5 weeks of data in 1 year and 4 weeks in another. The 

effects of these differences could seriously distort the 

seasonal factors if they were ignored in the seasonal 

adjustment process. These effects are modeled in the X-12-

ARIMA program and are permanently removed from the 

final seasonally adjusted series.
