Gross domestic product (GDP)	Gross domestic product (GDP) represents the total value of final products and services produced within the country’s territory during a year. GDP can be calculated on the basis of data on domestic production, demand (expenditure) and income at current and constant prices. From the production side GDP is formed by the income surplus from sales over the value of goods and services used up in production.
Statistical region	According to Cabinet of Ministers directions of April 28, 2004 “On statistical regions of Republic of Latvia and administrative units included in them” and the Nomenclature of Territorial Units for Statistics (NUTS3) of the European Union, the data are calculated on 6 statistical regions: 1) Riga region (Riga city); 2) Pieriga region (Jurmala city, Limbazi district, Ogre district, Riga district, Tukums district); 3) Vidzeme region (Aluksne district, Cesis district, Gulbene district, Madona district, Valka district, Valmiera district); 4) Kurzeme region (Liepaja city, Ventspils city, Kuldiga district, Liepaja district, Saldus district, Talsi district, Ventspils district); 5) Zemgale region (Jelgava city, Aizkraukle district, Bauska district, Dobele district, Jelgava district, Jekabpils district); 6) Latgale region (Daugavpils city, Rezekne city, Balvi district, Daugavpils district, Kraslava district, Ludza district, Preili district, Rezekne district).

Source of data	- CSB statistical survey 1-annual “Complex survey of enterprise activities”; - CSB statistical survey annual 1-KAU “Survey of the local KAUs activity”; - CSB statistical survey 2-annual “Complex survey of institution’s activity”; - State Revenue Service data; - Latvian State Institute of Agrarian Economics (LSIAE) data (till year 2008); - System of National Accounts of Latvia.
Coverage	Economically active enterprises in the statistical regions of the Republic of Latvia.
Sample size	Data on enterprises from 33 administrative territories of the Republic of Latvia (cities under state jurisdiction and districts in line with the “Classification of Administrative Territories and Territorial Units of the Republic of Latvia” (ATVK)) that according to activity sectors in NACE Rev.1.1 at two-digit level (58 from A01 to O93) were economically active in the respective year.
Description of data	Survey 1-annual: corresponding data from the largest and from the others economically active units of production taking into account the number of employees and turnover. Survey 2-annual: data from the budget-financed institutions. Survey 1-KAU annual: local KAUs survey from units, which provide 1-annual or 2-annual survey and have local KAU units; KAU economic activity’s codes (NACE Rev.1.1) and corresponding number of employees at this unit. State Revenue Service data: financial statements of small, micro, sole proprietors and non-profit institutions serving households. Latvian State Institute of Agrarian Economics (LSIAE) data (till year 2008): agricultural production produced in private farms (households). System of National Accounts of Latvia: main macroeconomic indicators.
Methods of calculation	GDP from the production approach is obtained by adding the net value of taxes on products to the GVA value. The net value of taxes on products is equal to difference between the total taxes and subsides on products. The regional gross value added is calculated according to the ESA95 European System of Accounts definitions and methods. The regional accounts methodology was elaborated additionally (“Regional Accounts Methods – Gross Value Added and Gross Fixed Capital Formation by Activity”). Regional Gross Value Added (GVA) calculation is based on the National GVA totals by kinds of activity in the country. The regionalization is performed on the base of data from the producer/institution LKAU located within the region territory (NUTS 3 level). If the activity of the unit of production is pursued in various region territories, its VA is divided between the respective regions taking into account the number of employees in the respective territory. Besides, gross value added for three NACE economic activities (agriculture, real estate activities, public administration and defense) is calculated in the following way: 1) Gross value added for activity A (NACE Rev.1.1) is formed as the sum of GVA of non-financial units and households. The total GVA in a household is divided by regions proportionally to the part produced by the rural farms from the respective territory in money terms; 2) For NACE Rev.1.1 activity K 70 (real estate, renting and other business activities) GVA of imputed rent is divided between regions in accordance with regional structure of the square metres and average rents of dwellings and management payments; 3) Gross value added for NACE Rev.1.1 L (public administration and defense) activity’s total is divided by regions proportionally to the number of employees in this activity and in respective region. The difference between the GVA totals in the national accounts and region territories is divided and allocated to each regional territory proportionally to the share of this territory in the total gross VA. Regional GDP from the production approach is obtained by adding the regional net value of taxes on products to the regional GVA value. The net value of taxes on products is divided and attached to the each region in accordance with this region GVA proportion in the total GVA.
Classification	- Classification of the Administrative territories and Territorial Units of the Republic of Latvia (ATVK); - NACE Rev.1.1. Statistical Classification of Economic Activities in the European Community; - Statistical Regions of the European Union - 3^rd level (NUTS3).
Revision	The published data are adjusted in line with the revision policy of the Macroeconomic Statistics Department.
Additional information	1) ATTANTION! Actually tables’ IK02, IK12, IK13, IK14 estimate ‘LATVIA - total’ (what is equal to sum of the regions’ totals) isn’t in the correspondence with the Annual National Accounts estimates because of transition to the new version of the Statistical Classification of Economic activities (NACE Rev.2) and other data revisions. Also the region’s total estimates (NACE 1.1.red.) in tables IK02, IK12, IK13, IK14 are not equal to the totals in tables IK021, IK121, IK141. 2) Beginning from the reference year 2009 the regions’ estimates calculation is based on the primary data sources what was gathered in accordance with NACE Rev.2. 3) In accordance with the European Commission regulation No 715/2010 of 10.08.2010 recalculated 2000-2008 years’ region time series shall be supplied at year 2012 no later than 30 December within the NACE Rev.2. 10 aggregated activities groups’ frames (A, B-E, F, G-I, J, K, L, M-N, O-Q, S-U). The 1995-1999 years’ region time series shall not be recalculated. 4) In order to bring the methodology of the main macroeconomic calculations closer to the requirements of the European System of Accounts (ESA95), gross value added and GDP value at current prices for the years 2000-2005 was changed in the 3^rd quarter of 2005; in the 4th quarter of 2006 and in the 1st quarter of 2008 the Gross Value Added and the value of GDP at current prices for the years 1996 - 1999 and 1995, respectively, was also changed. Recalculations are related to Regulation No.1889/2002 of the European Commission concerning financial intermediation services indirectly measured (FISIM). As a result of the calculations, adjustments were made to the value of FISIM which is comprised by the difference between the interest payments received and paid in the banking sector and broken down by the user sectors. For this reason data for the years starting with 1995 are not comparable with the data for previous periods. 5) Starting with reference year 2006 data improvements on regionalisation methods, what are concerned with real estate, renting and business activities (NACE Rev.1.1 K), were elaborated. The regionalisation method is applied for GVA of imputed rent. 6) From the reference year 2008 the LSIAE didn’t collected data about agricultural production produced by the rural farms by territories. Therefore the National account’s total estimate of A 01 (NACE Rev.1.1) is distributed by regions in the same proportion as for the reference year 2007.
