From autumn 1991 to spring 1998, the New Democracies Barometer (NDB) conducted nationwide sample surveys across Central and Eastern Europe. In each of ten countries (Bulgaria, the Czech Republic, Slovakia, Hungary, Poland, Romania, Slovenia, Croatia, Belarus and Ukraine) approximately 1,000 respondents were interviewed face-to-face about economic, political and social attitudes and behaviour. The same questions were asked in each country and repeated from year to year, so trends can be analysed across a wide variety of post-Communist societies, and over time. The data are also available from the UK Data Archive under GN 33355 by survey year.

Further information on the NDB is available on the CSPP New Democracies Barometer web page.
New Democracies Barometer I-V: Slovakia, 1991-1998 contains the original data and documentation of the surveys in Slovakia conducted as part of NDB from the first survey in 1991 to the fifth NDB survey in 1998, as well as a freestanding survey, the States and Markets surveys of 1991. The 1991 and 1992 surveys were designed to cover the whole of the Czechoslovak Federal Republic. At the time Czechoslovakia was a federal state, hence the separate Slovakia file has been created by allocating the Czechoslovakia respondents according to whether they were living in places subsequently included in Slovakia following their separation.
