The database includes approximately 100 variables. The IDA database covers the employment status, and workplaces and companies of the entire Danish population. People and companies are linked, and people can be characterised by information about their work place and vice versa.


A quality declaration is available in English at www.dst.dk/.../...abour-market-research--ida-.aspx


Linkage


From 1996, Statistics Denmark has classified the economic characteristics for the population into socio-economic categories and within these, further by occupational codes according to the DISCO-88 norm, which is a Danish version of the International Standard Classification of Occupations (ISCO).


Data from the IDA database can be linked to other register data available at Statistics Denmark through an encrypted identification key.


Data quality


N.A.


In 2008, there is a break since the data collection method changed. There is another break in 1996 regarding job designation. This break is caused by the introduction of DISCO 88. See the documentation for more information: www.dst.dk/.../ida-databasen.aspx


DISCO 88


Applicability


Strengths: This database covers the entire Danish population over time, which makes possible to analyse changes in labour market participation. Data further includes information about workplaces, which makes it possible to link information about colleagues and analyse the composition of the workplaces. Weaknesses: There are some breaks in data over time. See the documentation for more information: www.dst.dk/.../ida-databasen.aspx
