2.a. Definition and concepts

Definition:

The annual growth rate of real Gross Domestic Product (GDP) per employed person conveys the annual percentage change in real GDP per employed person.

Concepts:

GDP: It is the main measure of national output, representing the total value of all final goods and services within the System of National Accounts (SNA) production boundary produced in a particular economy (that is, the dollar value of all goods and services within the SNA production boundary produced within a country’s borders in a given year). According to the SNA, “GDP is the sum of gross value added of all resident producer units plus that part (possibly the total) of taxes on products, less subsidies on products, that is not included in the valuation of output … GDP is also equal to the sum of the final uses of goods and services (all uses except intermediate consumption) measured at purchasers’ prices, less the value of imports of goods and services GDP is also equal to the sum of primary incomes distributed by resident producer units.”

Real GDP: Real GDP refers to GDP calculated at constant prices, that is, the volume level of GDP, excluding the effect of inflation and favouring comparisons of quantities beyond price changes. Constant price estimates of GDP are calculated by expressing values in terms of a base period. In theory, the price and quantity components of a value are identified and the price in the base period is substituted for that in the current period.

Employment: All persons of working age who, during a short reference period (one week), were engaged in any activity to produce goods or provide services for pay or profit.

3.a. Data sources

Description:

Output measures used in the numerator of this indicator Gross Domestic Product (GDP) are best obtained from the production side of national accounts and represent, as much as possible, GDP at market prices for the aggregate economy (adjusted for inflation, in constant prices).

Employment data used in the denominator are preferably derived from labour force or other household surveys with an employment module. In the absence of a household survey, establishment surveys, administrative records or official estimates based on reliable sources can be used as well as population censuses. It is however important to note that employment data from establishment surveys will capture the number of jobs and not the number of persons employed as preferred for the denominator. Also, establishment surveys cover, in many cases, the formal sector and employers and employees only, not accounting for the whole economy.

When calculating this indicator, it is important to ensure that the coverage of the employment data is consistent with that of the national accounts.

3.b. Data collection method

For the purposes of international reporting on the SDG indicators, the ILO uses country-level estimates of GDP in constant 2015 US$ from the World Bank’s World Development Indicators database and country-level estimates on employment from household surveys or derived from the ILO modelled estimates to calculate levels and growth rates of labour productivity at the country, regional and global levels.

3.c. Data collection calendar

Continuous

3.d. Data release calendar

ILO estimates of labour productivity are part of the ILO modelled estimates series, analysed in the ILO's World Employment and Social Outlook reports. The ILO estimates are released once per year alongside these reports.

3.e. Data providers

Input GDP and employment data are provided by national statistical offices, and in some cases labour ministries or other related agencies.

3.f. Data compilers

International Labour Organization (ILO)

3.g. Institutional mandate

The ILO is the UN focal point for labour statistics. It sets international standards for labour statistics through the International Conference of Labour Statisticians. It also compiles and produces labour statistics with the goal of disseminating internationally comparable datasets, and provides technical assistance and training to ILO Member States to support their efforts to produce high quality labour market data.

4.a. Rationale

Real GDP per employed person being a measure of labour productivity, this indicator represents a measure of labour productivity growth, thus providing information on the evolution, efficiency and quality of human capital in the production process.

Economic growth in a country can be ascribed to many factors, including increased employment and more effective work by those who are employed. This indicator casts light on the latter effect, therefore being a key measure of economic performance. Labour productivity (and growth) estimates can support the formulation of labour market policies and monitor their effects. They can also contribute to the understanding of how labour market performance affects living standards.

4.b. Comment and limitations

Output measures are obtained from national accounts and represent, as much as possible, GDP at market prices for the aggregate economy. However, despite common principles that are mostly based on the United Nations System of National Accounts, there are still significant problems in international consistency of national accounts estimates, based on factors such as differences in the treatment of output in services sectors, differences in methods used to correct output measures for price changes (in particular, the use of different weighting systems to obtain deflators) and differences in the degree of coverage of informal economic activities.

Data on employment used in the denominator of this indicator refer, as much as possible, to the average number of persons with one or more paid jobs during the year. Employment data are based on the statistical standards from the 13th International Conference of Labour Statisticians (ICLS).

4.c. Method of computation

R e a l   G D P   p e r   e m p l o y e d   p e r s o n =   G D P   a t   c o n s t a n t   p r i c e s   T o t a l   e m p l o y m e n t

The numerator and denominator of the equation above should refer to the same reference period, for example, the same calendar year.

If we call the real GDP per employed person “LabProd”, then the annual growth rate of real GDP per employed person is calculated as follows:

A n n u a l   g r o w t h   r a t e   o f   r e a l   G D P   p e r   e m p l o y e d   p e r s o n =   ( L a b P r o d   i n   y e a r   n )   – L a b P r o d   i n   y e a r   n - 1 ( L a b P r o d   i n   y e a r   n - 1 )   × 100

4.d. Validation

The ILO engages in annual consultations with Member States through the ILOSTAT questionnaire and related Statistics Reporting System (StaRS). National data providers receive a link to the portal where they can review all national SDG data available on ILOSTAT.

4.e. Adjustments

Through the ILO Harmonized Microdata initiative, the ILO strives to produce internationally comparable labour statistics based on the indicator concepts and definitions adopted by the International Conference of Labour Statisticians.

4.f. Treatment of missing values (i) at country level and (ii) at regional level

  • At country level

Multivariate regression techniques are used to impute missing employment values at the country level.

For further information on the estimates, please refer to the ILO modelled estimates methodological overview, available at https://www.ilo.org/ilostat-files/Documents/TEM.pdf.

  • At regional and global levels

Regional and global figures are aggregates of the country-level figures including the imputed values.

4.g. Regional aggregations

To address the problem of missing data, the ILO designed several econometric models which are used to produce estimates of labour market indicators in the countries and years for which real data are not available. The employment data derived from the ILO modelled estimates are used to produce estimates on labour productivity. These models use multivariate regression techniques to impute missing values at the country level, which are then aggregated to produce regional and global estimates. For further information on the estimates, please refer to the ILO modelled estimates methodological overview, available at https://www.ilo.org/ilostat-files/Documents/TEM.pdf.

4.h. Methods and guidance available to countries for the compilation of the data at the national level

See:

4.i. Quality management

The processes of compilation, production, and publication of data, including its quality control, are carried out following the methodological framework and standards established by the ILO Department of Statistics, in compliance with the information technology and management standards of the ILO.

4.j. Quality assurance

Data consistency and quality checks are regularly conducted for validation of the data before dissemination in the ILOSTAT database. These checks consist of data and metadata revision of all the relevant inputs applying protocols to ensure that international comparability and time-series consistency are maintained. For the resulting modelled estimates, both statistical and judgmental assessments of the output data are carried out.

4.k. Quality assessment

The final assessment of the quality of information is carried out by the Data Production and Analysis Unit of the ILO Department of Statistics. If any issues encountered cannot be clarified, the respective information is not published.

5. Data availability and disaggregation

Data Availability:

Data for this indicator is available for 188 countries and territories.

Time series:

Data for this indicator is available as of 2000 in the SDG Indicators Global Database, but time series going back to 1991 and including estimates up to 2022 are available in ILOSTAT.

Disaggregation:

No disaggregation required for this indicator.

6. Comparability/deviation from international standards

Sources of discrepancies:

The main limitations of the use of labour productivity as a global indicator arise from problems in the international comparability of data, more specifically from methodological differences across countries. Even though national output measures, in particular GDP estimates, are derived mainly from national accounts which should be based on internationally agreed principles consolidated in the United Nations SNA, there are still significant obstacles to the international consistency of national accounts estimates. These range from differences in the treatment of the output of service sectors to adjustments for price changes and variations in the coverage of informal activities and the underground economy.

Employment or labour input figures also suffer from comparability issues, especially in terms of differences in age coverage, the definition of employment, geographical and institutional coverage, the treatment of special groups and the coverage of informal employment.

In cases where the contribution to GDP of forms of work other than employment are expected to be significant, such as in the case of own-use production of goods (subsistence agriculture and fishing) or volunteer work, the exclusion of participation and time-spent in these productive activities can be an important source of bias in the resulting indicators.
