MASS LAYOFFS – SEPTEMBER 2010

Employers took 1,486 mass layoff actions in September that resulted in the separation of 133,379 

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 September decreased by 60 from the prior 

month, the third consecutive over-the-month decrease. The number of associated initial claims decreased 

by 16,813 to its lowest level since April 2008. In September, 345 mass layoff events were reported in 

the manufacturing sector, seasonally adjusted, resulting in 34,168 initial claims. Both figures declined 

over the month. (See table 1.)

Industry Initial claims September peak

Industry Distribution (Not Seasonally Adjusted) 

The number of mass layoff events in September was 920 on a not seasonally adjusted basis; the number 

of associated initial claims was 77,654. (See table 2.) Over the year, the number of mass layoff events 

decreased by 451, and associated initial claims decreased by 45,523. Thirteen of the 19 major industry 

sectors in the private economy reported over-the-year decreases in initial claims, led by manufacturing. 

Agriculture reached a September program low in terms of average weekly claims. (Average weekly 

analysis mitigates the effect of differing lengths of months. See the Technical Note. Data began in 

1995.) 

The manufacturing sector accounted for 20 percent of all mass layoff events and 25 percent of initial 

claims filed in September. A year earlier, manufacturing made up 33 percent of events and 42 percent of initial claims. Within manufacturing, the number of claimants in September was greatest in 

transportation equipment and food. (See table 3.) Twenty of the 21 manufacturing subsectors experienced over-the-year decreases in initial claims, led by machinery. 

Government registered an over-the-year increase in mass layoff initial claims. (See table 3.) Year-todate initial claim totals through September for government are the highest on record (with data available 

back to 1996), reflecting layoffs in educational services and the completion of work on the decennial 

census. 

The six-digit industry with the largest number of initial claims in September was temporary help services. (See table A.) Of the 10 detailed industries in table A, transportation program administration 

reached a program high number of claims for the month of September. The table includes both publicly 

and privately owned entities. 
- 3 - 

Geographic Distribution (Not Seasonally Adjusted) 

All four regions and 8 of the 9 divisions experienced over-the-year decreases in initial claims due to 

mass layoffs in September. Among the census regions, the Midwest registered the largest over-the-year 

declines in initial claims. Of the geographic divisions, the East North Central and the Pacific had the 

largest over-the-year declines in initial claims. (See table 5.) 

California recorded the highest number of initial claims in September, followed by Florida, Pennsylvania, New York, and Illinois. Thirty-one states experienced over-the-year decreases in initial claims, 

led by California, Illinois, and Michigan. (See table 6.) The District of Columbia, North Dakota, South 

Dakota, West Virginia, and Wyoming matched September program lows for average weekly initial 

claims, while Idaho, Montana, and North Carolina reached program highs for the month in terms of 

average weekly initial claims. 

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 Extended Mass Layoffs news release for the Third Quarter 2010 is scheduled to be released 

on Friday, November 12, 2010, at 10:00 a.m. (EST). The Mass Layoffs news release for October 

is scheduled to be released on Tuesday, November 23, 2010, at 10:00 a.m. (EST). 
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:

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.
