Microdata and Method Development

The Microdata and Methodology Development Research Group pools the expertise for microdata analysis from the Institute's fields of competence and supports them in methodological issues.

Microdata originate from surveys and other statistical surveys that depict subjective and objective information of individual units such as persons, households or firms. The data enable application-oriented and policy-advisory analyses because they provide a representative picture of society. In addition to descriptive evaluations of, for example, income distribution, educational structure and corporate structures, microdata can also be used to identify correlations between variables. IW researchers use microdata in the areas of the labor market, education, public budgets and distribution, demographics, financial and real estate markets, and energy.

The IW has gained much experience in analyzing German and international microdata sets. Among them, for example, are the following:

  •     Socio-Economic Panel (SOEP)
  •     Microcensus
  •     Survey of Income and Consumption (EVS)
  •     General Population Survey of the Social Sciences (ALLBUS)
  •     Official Company Data for Germany (AFiD)
  •     Programme for the International Assessment of Adult Competencies (PIAAC)
  •     European Union Statistics on Income and Living Conditions (EU-SILC)
  •     Labor Force Survey (LFS)
  •     Household Finance and Consumption Survey (HFCS)
  •     International Social Survey Programme (ISSP)

In addition to its expertise in data analysis and econometric evaluation procedures, the Microdata and Methodology Development Research Group combines expertise in the field of simulation and forecasting models and supports the cross-institutional integration and further development of microdata-based models:

IW Population Forecast

The IW population forecast is a stochastic population forecast. Unlike the projections of official statistics, the uncertainty about future development is not represented by scenarios. Instead, forecast intervals depict the range of possible development. The IW population forecast covers the period up to 2035, and the record immigration of 2015 is included in the calculations of the future population level. The forecast thus differs from the 13th Coordinated Population Projection of the Federal Statistical Office not only in terms of methodology, but also in terms of its timeliness.

Acceptance of Parliamentary Procedures in the Light of Individual Problem Perception

Matthias Diermeier / Judith Niehues

A lively democracy thrives on the struggle between different interest groups for majority opinion on specific issues. Though the institutionalised process of balancing interests and hearing opposing points of view takes time, acceptance of these parliamentary procedures is essential for the functioning of our pluralistic democracy.

Equality of Educational Opportunity: A Challenge for the German Education System

Christina Anger / Axel Plünnecke

Germany has been making good progress towards achieving equality of opportunity in its education system. Latterly, however, it has become clear that the correlation between socio-economic background and educational success is again becoming more pronounced, a phenomenon which can be partly attributed to the high level of immigration in recent years.

Stable Through the Crisis?: Distributional Consequences of the Corona Pandemic - A Microsimulation Analysis

Martin Beznoska / Judith Niehues / Maximilian Stockhausen

The corona pandemic has had a decisive impact on the year 2020 and, at least in recent times, has had an unprecedented (negative) impact on society and the economy. At the core of this simulation study is therefore the question of how the corona pandemic has affected income levels and social inequality in Germany, and to what extent automatic stabilizers of the social security system and additional financial aid measures have been able to cushion distortions caused by the crisis.
