The main aim of structural business statistics
The main aim of structural business statistics is to show the structure of the business sector with regard to economic data. Statistics are presented by economic activity, classified by Statistical Classification of Economic Activities (Nace Rev 2) and size class of enterprise which are classified by number of employed 1-4, 5-9, 10-49, 50 and more employed.
Legal framework on which is based the annual structural business survey is composed of Law no. 9180, dated 05.02.2004 “On official statistics”, amended and Official Statistics Programme for the period 2012-2016.
Safety of data and confidentiality
The data collected from enterprises are considered strictly confidential and used only for statistical and scientific research purposes in accordance with Law no. 9180, dated 05.02.2004 “On official statistics”, amended, and Law no. 9887, dated 10.03.2008 “Protection of Personal Data”. Article 15 of the law “On official statistics” clearly states that all information collected by INSTAT is confidential and may be used or published only in summary tables that do not identify the information source unit.
Structural business statistics are regulated by Council Regulation (EC, EURATOM) No. 58/97, 20 December 1996. For being in compliance with European regulation, structural business statistics are produced according to the below European Commission regulations:
- Regulation (EC) No. 1893/2006 for “Implementation of NACE Rev.2 in Structural Business Statistics”.
- Regulation (EC) No. 295/8 for “Structural Business Statistics”.
- Regulation (EC) No. 250/2009 for “Definitions used in Structural Business Statistics”.
Classifications and definitions
Classification of economic activities
The classification of enterprises is done according to Classification of Economic Activities, NACE Rev.2. For more information, please refer to the following link:
The economic activities include all enterprises that produce goods or services for the market. Agriculture, hunting and fishing activities, financial and insurance activities, public and defence administration; compulsory social security and extraterritorial organizations and bodies are not part of the survey.
Data are collected for calendar year. The fiscal year corresponds to the calendar year.
Size class of enterprises
Enterprises are classified on size classes by number of employed (measured as employed on a full-time basis).
The statistics comprise all active enterprises in Albania, of all legal forms. The population consists of all enterprises that, according to statistical business register were active in December of the reference year.
Enterprises with 1-9 employed are surveyed by sample survey. Enterprises with 10 and more employed are surveyed exhaustively.

Extraterritorial organizations and bodies
The survey includes basic and macroeconomic indicators. The basic indicators include information related to economic activities, employment, incomes and expenditures and investments. Macroeconomic indicators, as production, intermediate consumption, value added, etc., are calculated based on basic indicators. Parts of the publication are also specific indicators for volume of construction, road transport, hotel, bar café and restaurants.
Definition of indicators
An enterprise is: “the smallest combination of legal units that is an organisational unit producing goods or services which benefits from a certain degree of autonomy in decision-making, especially for the allocation of its current resources. An enterprise carries out one or more activities at one or more locations (local unit)”. The relationship between an enterprise and a legal unit is therefore defined as: “the enterprise corresponds either to a legal unit or to a combination of legal units”.
Employed is defined as the total number of persons who work in the observation unit including proprietors, employees and unpaid family workers.
Turnover comprises the totals amount invoiced by the observation unit during the reference period, and this corresponds to market sales of goods or services supplied to third parties.
Investments during the reference period includes the goods, whether bought from third parties or produced for own use, having a useful life of more than one year including non-produced tangible goods such as land.
The production is an activity exercised under the control and responsibility of an institutional unit (enterprise), which combines the sources of labor forces, capital and raw materials to produce goods and perform services.
The value of production is based on:
Incomes from the sale of goods and services (turnover) realized by the enterprise:
(±) Changes in stocks of work in progress, finished goods and work on contract
(±) Changes in goods and services purchased for resale in the same condition as received
(–) Purchases of goods and services purchased for resale in
the same condition as received
(+) Capitalized production
Intermediate consumption represents the value of products or services transformed or totally consumed during the production process. The uses of fixed assets in work are not taken in consideration.
Value added at basic prices is calculated as difference between production value and intermediate consumption.
Wages and salaries per employees corresponds to the annual average wages and salaries paid from enterprise per an employees.
Median and Quartiles
Median is the middle item in the rank-ordered list of numbers, (ascending order in this case). If there are an odd number of items, the median is the value of the middle item and if there is an even number of items, the median is the average value of the two middle items.
Quartiles divide the data in the rank ordered list of numbers (ascending order in this case) into four parts, with each part containing an equal number of items.
1st quartile indicates that 25 percent of all the values in the ordered list are less than this value.
2nd quartile is equal to the median and indicates that 50 percent of all the values in the ordered list are less than this value.
3rd quartile indicates that 75 percent of all the values in the ordered list are less than this value.
How the statistics are treated
The data are collected directly from enterprises with interviewers. The printed questionnaire is filled in at the moment of interview in enterprises.
Treatment of non-response
Are considered as all cases of:
- Full refuse
- Partial refuse (for different tables and indicators).
The treatment of partial non-response is done using direct methods or their combinations such as:
- Study of time series of enterprise and sector data;
- Data from balance-sheet file;
- The information from other files available in INSTAT such as:
- Statistical Business register;
- VAT file;
- File of production price index.
- Average data of sector where the enterprise is included are analyzed and used;
- Data from enterprises that have similar conditions are used;
- Method of average structure, especially for expenditures is used;
- For the part remained without treatment is used re-weighting method.
Quality of data
There are applied some rules for analysing quality of data:
- Mathematic control of the questionnaire
- Logic control of the questionnaire’s data
- Comparison of time series data
- Comparison of data with other files available in INSTAT
- Comparison of data with balance sheet file
- Determination of some ratios’ limits for example, average wages and salaries per employee, margin per turnover, etc.
- Analyse of huge deviations from average.
