Series Information
The main purpose of the Labour Force Survey is to provide information on the main characteristics of employment and unemployment in the Republic of Bulgaria. In June and October 1994 two survey rounds were carried out. From 1995 to 2000, the survey has been conducted three times a year, the sample size decreased from 30,000 to 24,000 households. In 2000-2002 the survey delivered quarterly results based on a single reference week in the last month of the quarter. In 2003 the survey was redesigned as a continuous Labour Force Survey, providing quarterly results.
The following classifications are used in the survey: International Standard Classification of Education - Revision 1997 (ISCED - 97); Classification of Economic Activities - 2008 - in force since 2008, which is a Bulgarian version of NACE, Rev. 2; National Classification of Occupations - 2005 (1st digit - occupational class), comparable to the International Standard Classification of Occupations – ISCO ’88, in force until 2010; National Classification of Occupations - 2011 (1st digit - occupational class), comparable to the International Standard Classification of Occupations – ISCO ’08, in force since 1 January 2011; International classification of professional status - ICSE-93; Classification of Territorial Units for Statistical Purposes in Bulgaria, harmonized with the European Classification of Territorial Units for Statistics - NUTS.

Abstract
The Labour Force Survey is the largest regular household sample survey carried out in Bulgaria. It provides information on economic activity of the population - employment and unemployment, according to the internationally adopted concepts and definitions. Some of the most important indicators of socio-economic development of the country, as activity rate, employment rate and unemployment rate are calculated on the base of the Labour Force Survey.
The survey covers the whole country. Only private households are included. Persons, living in student or workers' hostels are treated as private households. All households, covered in the sample, are surveyed within three months with the reference period evenly spread throughout 12 weeks of the quarter. Data is collected by personal interviews with household members 15 years old and over.
An ad hoc module "Organisation of work and working time arrangements" was added in the Labour Force Survey in the second quarter of 2004. The module examined types of working time, shift work and atypical working time (for example, in Saturdays or Sundays).

Questionnaires
Questionnaires
Two types of questionnaires are used in the Labour Force Survey:
- Household Questionnaire.
Household questionnaire is filled in for each household at the first visit and is used for all four interviews.
- Individual Questionnaire.
This type of questionnaire is filled in for persons 15 years old and above, permanently living in the household. Information could be filled for four household members - one in each column. A new questionnaire has to be filled in if there are more than four household members aged 15 and more. Identity part of the individual questionnaire (district, settlement, number of the cluster within the district, number of the household within the cluster, date of the last day of the observed period) has to correspond fully to the identity part of the household questionnaire.

Data Processing
Data Editing
Interviewers from the regional statistical offices visit the selected households and interview persons living in these households. Filled-in questionnaires are coded and data entry is done on PC at the regional statistical offices. Primary data is sent to the National Statistical Institute, where it is weighted at national level. Weighted data is broken down by different characteristics: total, by sex, age, urban/rural areas, level of education, professional status, occupation, by statistical regions and districts. Data is tabulated for dissemination and publishing.
