TECHNICAL NOTES
 
     The tables in this news release present international comparisons of 
hourly compensation costs for all employees and production workers in 
manufacturing in selected countries or areas.  The total compensation 
measures are prepared by the Bureau of Labor Statistics in order to assess 
international differences in employer labor costs.  For several reasons, the 
comparisons based on the more readily available average earnings statistics 
published by many countries can be misleading: national definitions of 
average earnings differ considerably; average earnings do not include all 
items of labor compensation; and the omitted items of compensation 
frequently represent a large proportion of total compensation.
     
     The compensation measures in this news release are based on statistics 
available to BLS as of January 2009.   These measures may be revised as 
data are collected to update compensation measures for component 
industries.  Data for component industries are available at 
http://www.bls.gov/fls/flshcindnaics.htm.  


Definitions
     
     Hourly compensation costs include (1) hourly direct pay and (2) 
employer social insurance expenditures and other labor taxes.  Hourly 
direct pay includes all payments made directly to the worker, before 
payroll deductions of any kind, consisting of pay for time worked and 
other direct pay.   Social insurance expenditures and other labor taxes 
refers to the value of social contributions incurred by employers in order to 
secure entitlement to social benefits for their employees; these 
contributions often provide delayed, future income and benefits to 
employees. Included are employer expenditures for legally required 
insurance programs, contractual and private benefit plans, and other labor 
taxes.  Other labor taxes refer to taxes on payrolls or employment (or 
reductions to reflect subsidies), even if they do not finance programs that 
directly benefit workers.  
    
The BLS definition of hourly compensation costs is not the same as 
the International Labor Office (ILO) definition of total labor costs.  BLS 
hourly compensation costs do not include all items of labor costs.  
Expenditures on the maintenance and repair of facilities related to 
company-provided services—such as cafeterias, daycare centers, private 
medical clinics, and recreational facilities— are excluded because they are 
overhead costs not directly linked to the level of employment or payroll.  
Recruitment and vocational training costs and reimbursements of business 
expenses are not included because the concepts used, and thus the 
measurement of these items, are not consistent across countries.  The above 
labor costs items not included account for no more than 2 percent of total 
labor costs in most countries for which the data are available.

    Production workers generally include those employees who are 
engaged in fabricating, assembly, and related activities; material handling, 
warehousing, and shipping; maintenance and repair; janitorial and guard 
services; auxiliary production (for example, power plants); and other 
services closely related to the above activities.  Working supervisors are 
generally included; apprentices and other trainees are generally excluded.

    All employees include production workers as well as all others 
employed full or part time in an establishment during a specified payroll 
period.  Temporary employees are included.  Persons are considered 
employed if they receive pay for any part of the specified pay period.  The 
self-employed, unpaid family workers, and workers in private households 
are excluded.

Data on Hourly Direct Pay, Pay for Time Worked, and Social Insurance 
Expenditures can be found in the supplementary tables to this news release 
at http://www.bls.gov/ilc/hcaesupptabtoc.htm for all employees and 
http://www.bls.gov/ilc/hcpwsupptabtoc.htm for production workers.


Methods

    Total compensation is computed by adjusting each country's average 
earnings series for items of direct pay not included in earnings and for 
employer expenditures for legally required insurance, contractual and 
private benefit plans, and other labor taxes and subsidies.  For the United 
States and other countries that measure earnings on an hours-paid basis, 
the figures are also adjusted in order to approximate compensation per 
hour worked.

    Earnings statistics are obtained from surveys of employment, hours, 
and earnings, from surveys or censuses of manufactures, or from 
administrative data sources.  The surveys used in the BLS series typically 
cover firms with a minimum of one to ten employees. 

    For most countries, average earnings are adjusted to total 
compensation using adjustment factors obtained from periodic labor cost 
surveys or censuses of manufacturers; the adjustment factors are 
interpolated or projected to non-survey years on the basis of other 
information.  Generally, these surveys cover all employees in the 
establishment; survey data are used for both production worker and all 
employee series.  Other information used includes tabulations of employer


                              -12-

 
social security contribution rates provided by the International Social 
Security Association, information on contractual and legislated fringe 
benefit changes, and statistical series on indirect labor costs.  For the 
United States, the adjustment factors are specially constructed for 
international comparisons using data from several surveys. The methods 
used, as well as the results, differ somewhat from those for other BLS 
series on U.S. compensation costs.

    The statistics are also adjusted, where necessary, to account for major 
differences in worker coverage; differences in industrial classification 
systems; and changes over time in survey coverage, sample benchmarks, or 
frequency of surveys.  Nevertheless, some differences remain. Exceptions 
to these methods, as well as data sources used can be found in "Country 
Notes and Sources" located at www.bls.gov/ilc.     


Exchange Rates and Currencies 
    
    Hourly compensation costs are converted to U.S. dollars using the 
average daily exchange rate for the reference period.  The exchange rates 
used are prevailing commercial market exchange rates as published by 
either the U.S. Federal Reserve Board or the International Monetary Fund.

        On January 1, 1999, several European countries joined the European 
Monetary Union (EMU): Austria, Belgium, Finland, France, Germany, 
Ireland, Italy, Luxembourg, the Netherlands, Portugal, and Spain.  Greece 
joined on January 1, 2001 and Slovakia joined on January 1, 2009.  There 
are currently other member countries of the EMU that are not covered in 
this report.  Currencies of EMU members were established at fixed 
conversion rates to the euro, the official currency of the EMU. For the 
EMU countries, with the exception of Greece, data on hourly  
compensation costs are published in the old national currencies used in 
each country before the  adoption of the euro from 1992-1998 and in euros 
from 1999-2006. Data for Greece are reported in drachmas from 1992-
2000 and in euros from 2001-2006. Slovakia will be reported in euros 
beginning with 2009 data.


Industrial classification

    The hourly compensation measures relate to manufacturing on a North 
American Industry Classification System (NAICS) basis.  NAICS is the 
common industrial classification used by the United States, Canada, and 
Mexico.  The NAICS definition of manufacturing differs somewhat from 
the definition of manufacturing used in other countries.  Some industries 
that are not included in the NAICS definition of manufacturing, such as 
publishing of books and sound recordings, some repair and maintenance of 
equipment, and some business support services, are included in the 
definition of manufacturing in most other industrial classifications.  In 
contrast, other industries are included in the NAICS definition of 
manufacturing but not in the definition of manufacturing for most foreign 
economies, such as some processing of foods, some packaging, and retail 
sales of bakery products from the production facility.  Most of the 
differences other than the treatment of publishing are very minor and do 
not have a noticeable impact on overall manufacturing averages.   BLS 
makes adjustments to remove publishing from manufacturing for the 
foreign economies in which it is classified as a part of manufacturing— 
except for Sri Lanka, Luxembourg, Slovakia, and Switzerland, for which 
the data necessary to remove publishing are not available.  For the 
countries for which adjustments are made, the effect of publishing on 
manufacturing wages is estimated and removed using data from national 
sources or the United Nations Industrial Statistics Database.  Except for 
Hong Kong, the effect of removing publishing from manufacturing does 
not change the level of hourly compensation costs for any economy more


                              -13-
 
than 1.5 percent, and the change is less than one percent in most countries.  
For Hong Kong, the effect of the adjustments is 2 to 4 percent in several 
years.   


Trade-weighted measures

    The trade weights used to compute the average compensation cost 
measures for selected economic groups are weights based on the relative 
dollar value of U.S. trade in manufactured commodities (exports plus 
imports) with each country or area in 2007.  (See the following table.)  The 
trade data are compiled by the U.S. Census Bureau. 
 
    The only countries not covered in the trade-weighted measures of this 
report that accounted for as much as one percent of such trade in 2007 are 
China, India, Malaysia, and Thailand.  Hourly compensation costs data for 
China are included in this report in a special text box.  In addition, an 
article on manufacturing compensation costs in China is available on the 
BLS website at http://www.bls.gov/opub/mlr/2006/11/art4full.pdf.  The 
compensation data on China are not directly comparable with the data for 
other countries found in this news release.

    The countries included in the Organization for Economic Cooperation 
and Development (OECD) trade-weighted measure are Canada, Mexico, 
Australia, Japan, the Republic of Korea, New Zealand, and all European 
countries covered in the series.  The group labeled "Euro Area" consists of 
the 13 European Union member countries in this release that have adopted 
the euro as the common currency as of January 1, 2009 (Austria, Belgium, 
Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the 
Netherlands, Portugal, Slovakia, and Spain).  The group labeled "Europe" 
consists of the members of the Euro Area and the Czech Republic, 
Denmark, Hungary, Norway, Poland, Sweden, Switzerland, and the 
United Kingdom. The group labeled "Eastern Europe" consists of the 
Czech Republic, Hungary, Poland, and Slovakia. The group labeled "East 
Asia ex-Japan" consists of Hong Kong SAR, the Republic of Korea, the 
Philippines, Singapore, and Taiwan.

    The trade-weighted measures relate to all the countries or areas 
covered in the series.  If data for the most recent year(s) are missing for a 
country, trade-weighted estimates are computed using the average percent 
change of all the other economies in the series to estimate the missing 
year(s).  An economy is included in trade-weight series beginning with the 
start year of that economy’s data series.

    The trade-weighted average rates of change are computed as the 
trade-weighted arithmetic average of the rates of change for the individual 
countries or areas; the trade-weighted average hourly compensation costs 
are computed as the trade-weighted arithmetic average of cost levels for 
the individual countries or areas.  Rates of change derived from the trade-
weighted average hourly compensation cost levels need not be the same as 
the trade-weighted average rates of change.

Data limitations

     Because compensation is partly estimated, the statistics should not be 
considered as precise measures of comparative compensation costs.  In 
addition, the figures are subject to revision as the results of new labor cost 
surveys or other data used to estimate compensation costs become 
available.

     The comparative level figures in this report are averages for all 
manufacturing industries and are not necessarily representative of all 
component industries.  In the United States and some other countries, such 
as Mexico and Taiwan, differentials in hourly compensation cost levels by 
industry are fairly wide.  


Labor costs versus labor income

    The hourly compensation figures in U.S. dollars shown in the tables 
provide comparative measures of employer labor costs; they do not 
provide inter-country comparisons of the purchasing power of worker 
incomes.  Prices of goods and services vary greatly among countries, and 
the commercial market exchange rates used to compare employer labor 
costs do not reliably indicate relative differences in prices.  Purchasing 
power parities, that is, the number of foreign currency units required to 
buy goods and services equivalent to what can be purchased with one unit 
of U.S. or another base currency, must be used for meaningful 
international comparisons of the relative purchasing power of worker 
incomes.

    Total compensation converted to U.S. dollars at purchasing power 
parities would provide one measure for comparing relative real levels of 
labor income.  It should be noted, however, that total compensation 
includes employer payments to funds for the benefit of workers in 
addition to payments made directly to workers.  For some countries, the 
compensation measures also include taxes or subsidies on payrolls or 
employment even if they do not finance programs which directly benefit 
workers.  Payments into these funds provide either deferred income (for 
example, payments to retirement funds), a type of insurance (for example, 
payments to unemployment or health benefit funds), or current social 
benefits (for example, family allowances), and the relationship between 
employer payments and current or future worker benefits is indirect.  On 
the other hand, excluding these payments would understate the total value 
of income derived from work because they substitute for worker savings 
or self-insurance to cover retirement, medical costs, etc.

    Total compensation, because it takes account of employer payments 
into funds for the benefit of workers, is a broader income concept than 
either total direct earnings or direct spendable earnings.  An even broader 
concept would take account of all social benefits available to workers, 
including those financed out of general revenues as well as those financed 
through employment or payroll taxes.
