ISMF INTERNATIONAL STRATIFICATION AND MOBILITY FILE The
International Stratification and Mobility File [ISMF] is a collection of
harmonized sample survey data with information on social stratification and social
mobility, in particular respondent's and parents’ social statuses (education,
occupation). The data set is created and maintained by Harry B.G. Ganzeboom at Free
University Amsterdam, in collaboration with Donald
J. Treiman and Elizabeth Stephenson,
The
goal of the ISMF project is to create a comparative database to study social
mobility patterns over time and throughout the world. To this end, the ISMF aims to be as
comprehensive as possible in its inclusion of all surveys that meet the
specified criteria (see below). For
some nations, included surveys extend as far back as the 1940’s and are as
recent as 2008. As of November 2009
the database includes more than 250 surveys, from 52 nations. With time measured
by 5-year birth cohorts, these surveys include data for over 400 nation*time
combinations. In all, about one
million individuals, both men and women, are included in the database. Criteria
for inclusion in the ISMF are: ·
The
survey contains information on father's occupation, respondent's level of
education, and respondent's current occupation, which together define the
most elementary status attainment model. ·
The
survey is representative of a national or sub-national population. "Sub-national" refers to
political units that are parts of larger states but that have distinct
identities, separate education systems, separate labor markets, and sometimes
separate languages. Examples include ·
The
survey is available to researchers at no cost or low cost. See
overview of harmonized variables in ISMF. DISTRIBUTION The
ISMF itself is currently not available for distribution: researchers should
acquire the source data at the respective data-archives and generate their
own harmonized extract file. However, we do provide researchers with some
important tools for harmonization efforts, in particular maps to recode
occupation and education categories into internationally and historically
comparable metrics. Researchers are free to use and adapt these tools for
these purposes, but are asked to cite these tools using the following

modules are formatted as SPSS syntax files, and should open in SPSS on any
computer that has this widely distributed statistical software package
installed. Otherwise, they can be read as straight ASCII (.txt) files. Further
