MASS LAYOFFS – JANUARY 2011 

Employers took 1,534 mass layoff actions in January involving 149,799 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 mass layoff event involved at least 50 workers from a single employer. The number of mass layoff events in January increased by 51 from December, and the number 

of associated initial claims increased by 11,807. In January, 341 mass layoff events were reported in the 

manufacturing sector, seasonally adjusted, resulting in 39,189 initial claims; both figures increased over 

the month. (See table 1.)

Private nonfarm

The national unemployment rate was 9.0 percent in January, down from 9.4 percent the prior month and 

9.7 percent a year earlier. In January, total nonfarm payroll employment increased by 36,000 over the 

month and by 984,000 from a year earlier. 

Industry Distribution (Not Seasonally Adjusted) 

The number of mass layoff events in January was 2,558 on a not seasonally adjusted basis; the number 

of associated initial claims was 246,463. (See table 2.) The number of mass layoff events was down by 

302 from January 2010, and associated initial claims decreased by 32,216. Eleven of the 19 major industry sectors in the private economy reported over-the-year declines in initial claims, with manufacturing having the largest decrease. The six-digit industry with the largest number of initial claims in 

January 2011 was temporary help services. (See table A. The table includes both publicly and privately 

owned entities.)

Industry Initial claims January peak

The manufacturing sector accounted for 27 percent of all mass layoff events and 30 percent of initial 

claims filed in January. A year earlier, manufacturing made up 34 percent of events and 38 percent of 

initial claims. Within manufacturing, the number of claimants in January was greatest in transportation 

equipment and in food. (See table 3.) Eighteen of the 21 manufacturing subsectors experienced over-theyear decreases in initial claims, with the largest declines in machinery and fabricated metal products. 

Geographic Distribution (Not Seasonally Adjusted) 

Three of the 4 regions and 7 of the 9 divisions experienced over-the-year decreases in initial claims due 

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

decrease in initial claims. Of the geographic divisions, the East North Central had the largest over-theyear decline in initial claims. (See table 5.) 

California recorded the highest number of initial claims in January, followed by New York and Pennsylvania. Thirty-two states experienced over-the-year decreases in initial claims, led by Michigan, Ohio, 

and Illinois. (See table 6.) 

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 
- 3 - 

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 news release for February is scheduled to be released on Tuesday, March 22, 

2011, 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:

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.
