TECHNICAL NOTES

     The tables in this news release present international comparisons of 
hourly compensation costs for production workers and all employees 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 September 2007.  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.

     For the first time, this news release contains data for all employees in 
addition to the series for production workers.  The production worker series 
starts in 1975 and the all employee series in 1996.  In addition, production 
worker and all employee data are introduced for the Philippines and all 
employee data are introduced for Argentina and Slovakia.


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 include 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, because such taxes are regarded as 
labor costs.

     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.  The costs of 
recruitment, employee training, and plant facilities and services--such as 
cafeterias and medical clinics--are not included because data are not available 
for many countries.  The labor costs 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 also excluded.

Expenditures can be found in the supplementary tables to this news release at

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 or from surveys or censuses of manufactures.  These surveys typically 
cover firms with a minimum of one to ten employees.  

     For most countries, adjustment factors are obtained from periodic labor 
cost surveys or censuses of manufacturers and 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 in both 
production worker and all employee series.  Other information used includes 
tabulations of employer social security contribution rates provided by the 
International Social Security Association, information on contractual and 
legislated fringe benefit changes from labor bulletins, 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.


                                 -11-

     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 can be found in "Country Notes and 
Sources" located at www.bls.gov/fls.


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.  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 data on hourly compensation costs are reported in euros and 
exchange rates for the EMU countries relate to euros per dollar for 1999 to 
the present; for the years 1975-1998, hourly compensation data are published 
in the old national currencies used in each country before the adoption of the 
euro.  In order to include data on trends in national currency compensation 
costs and exchange rates for the entire time period, BLS converts national 
currency for 1975-1998 to a "euro" basis for calculation.  The conversions for 
all years 1975-1998 are made using the official fixed conversion rates for 
1999, with the exception of Greece which uses the official fixed conversion 
rate for 2001.


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, 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, the 
International Labor Office (ILO), and other sources.  Except for Hong Kong, 
the effect of removing publishing from manufacturing does not change the level 
of hourly compensation costs for any economy more than 1.5 percent, and the 


                                 -12-
                                 
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 2004.  (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 2004 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 12 European 
Union member countries in this release that have adopted the euro as the 
common currency as of January 1, 2001 (Austria, Belgium, Finland, France, 
Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, and 
Spain).  The group labeled "Europe" consists of the members of the Euro Area 
and the Czech Republic, Denmark, Hungary, Norway, Poland, Slovakia, Sweden, 
Switzerland, and the United Kingdom.  The group labeled "Asian NIEs" consists 
of the four newly industrialized economies of Hong Kong SAR, the Republic of 
Korea, 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 


                                 -14-
                                 
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 other base-country 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 a few 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.
