Motivations for harmonisation
Microcensus Housing Survey, Household Budget Survey, EU-SILC
…all include questions on housing
…are continuous and established surveys
…are highly relevant for the Austrian social statistics and the ESS
…are strongly interrelated
…are linked to other statistics within Statistics Austria

Interests and legal frameworks
Employment, structure of families and
households
Housing situation, housing costs, stock of
dwellings Microcensus
Income and living conditions in the EU,

Harmonisation is necessary and possible
but there are limitations
…due to different aims and interests
…due to legal regulations and frameworks
…due to concerns about break in time series
…due to interrelations with surveys and statistics which are not in the focus of harmonisation

What will be done next…
Data based on harmonised questions
• Microcensus & EU-SILC 2014: surveys will deliver data on basis of harmonised variables analyse & compare
• Household Budget Survey will follow 2015
New publication on housing
• Main report on housing will be re-established in 2014
• Including several statistics on housing (focus on social statistics)
• Communicate differences/similarities of concepts, definitions, terms and data

Conclusions
Though harmonisation
• is a time-consuming and difficult process
• which is related to all stages of a survey
the gains of harmonisation compensate for difficulties
• easier and methodologically sound comparisons of data
• better handling of existing interrelations
• better matching of datasets
