ParlGov is a data infrastructure for political science. It contains information for all EU and most OECD democracies (37 countries) from 1945 until today. The database combines approximately 1400 parties, 770 elections (7300 results), and 1100 cabinets (2800 parties).
We keep information about all contributors to the ParlGov project in a credits file.
Establish ParlGov as a platform for collaborative data collection in political science
Extend types of data covered -- funding and cooperation partners needed
Party positions are based on various party expert surveys and sources vary for the dimensions we include. We have a page with more detailed information.
A stable versions is archived once a year and we document changes between stable versions.
An experimental version can be accessed after signing in and it includes data (tables and variables) that are not included in the next stable version. It is a superset of the development version.
Primary data?: Information we collect and save in the ParlGov database. To be more specific, these are those database table that we actively maintain and that are based on various data sources.
External data?: Datasets that have been collected by other researchers and are linked to ParlGov data. You can combine this data with ParlGov observations through id variables or/and scripts. You have to cite the usage of these data separately.
Views?: Some observations can be calculated from primary data. This information is stored in seperate tables (views) and is generated automatically by the database. Relying on views avoids data redundancy, so that we have to update every observation only once.
Calculated parameters?: Some parameters can not be constructed through views and have to be calculated. Currently, we determine these values with various R scripts. As a consequence, these observation contain a variable that gives information about the date of calculation. We may update these scripts in the future and turn it into dynamic calculations.
We provide one stable version every year.
Stable releases up to ParlGov 12/10 included a static copy of the webpage and all tables from the database. Creating this copy was a mundane, time cosuming and unreliable endevor. Hence, we have abondonded dumping the entire page and all tables for a stable version.
Please get in touch if you would like to provide data, scripts, feedback.
