Labour productivity is an economic indicator that compares the result achieved (newly created product) with input labour factor when carrying out an economic activity of an economic territory for a specified period. This indicator provides estimates of the growth rate of labor productivity. At national level, the result of productive activity is measured by Gross Domestic Product (GDP) and value added (VA) generated by all manufacturing sectors in the national economy. All evaluations are made in accordance with accepted practices on national accounts to allow for comparability of labor productivity across sectors. The labor productivity is a key indicator of the achieved level of economic development.

|Statistical concepts and definitions|
The main components of labor productivity are indicators measuring the result of performed the manufacturing activity (numerator) and indicators of labor input in the production process (the denominator).
At the national level, the result of the production activity is measured with Gross Domestic Product (GDP) and Gross Value Added (GVA) created by all the productive sectors of the national economy. GDP is a key indicator in the system of national economic accounts, which represents the final result of the production activity of all resident producer units (ESNS2010, 8.89). The relationship between GDP and GVA is determined by how quantification works finished product. GDP is valued at market prices, including taxes on products and imports net of subsidies on products. GVA measures the result of the production activity at basic prices before taxes, including subsidies on products and services. BDS is an indicator that is applicable to the calculation of labor productivity at the national level and at the level of production activities or regions.
The use of this indicator in the national practice is consistent with the specific methodological scope of the sector " Letting of own property " activity of CEA 2008 - in the composition of GVA includes assessing the imputed rent of dwellings rented by their owners , who for Bulgaria is dominant - almost 90 % of the population live in their own homes. Added value of imputed rent of owner-occupiers is classified entirely as operating surplus in the composition of the account "Generation of income" and is not directly connected with employment. For this reason, value added as a result of contingent rental housing is excluded in calculating the productivity of labor in the services sector and the economy as a whole.
Labor factor in production in the composition of the index of labor productivity is measured by the number of persons employed in resident production units of the national economy and spent their time - hours worked.
Measurement of the number of employees and hours worked by them is subject to the definitions and concepts (ESA2010 11.11, 12.11) , as these concepts and definitions apply in assessing the performance of the result of their economic activity .

|Data revision - policy|
In practice, the system of national accounts, there are two main types of revisions beyond the scope and content of the methods of seasonal adjustment. The first type of audits is ongoing, regular characterized by the presence of new or updated statistical information based on statistical surveys or administrative sources. The second type of revisions is related to a change in the methodology and calculation procedures for specific statistical indicators
|Data revision - practice|
National accounts data are subject to continuous routine revisions as new input data becomes available. This will typically also entail revisions of the national accounts aggregates, which are derived from these data. In BG national accounts two types of revisions are: regular – preliminary, final data; and main - based on implementation of new methodology or GNI reservations.
|Data revision - average size|
|Timeliness and punctuality|

· Updated annual data - T +9 months after the reporting period;
· Final data - balance sheets "Resource-Use" - T +3 years.
