This is the fifth living standards measuring survey conducted in Bulgaria. The first Integrated Household Survey (IHS) was conducted in 1995 on a sample of approximately 2,500 households. The second round was conducted in 1997 on the 1995 sample and the third IHS was conducted in 2001. From 2003, the study is known as Multitopic Household Survey (MTHS).
The 2007 MTHS replicates the 2003 survey, in terms of both survey design and thematic coverage to ensure their comparability. Both surveys were similarly administered with nearly identical questionnaires and sampling designs, and were based, respectively, on more than 3,100 and 4,300 households randomly selected via three-stage probability sampling procedure with stratification by urban and rural areas and by region.
