Data Usage

The OPPA partners are committed to making collected microdata available to the research community in a timely fashion and at minimal costs (mostly free of charge). We distinguish two types of data:

  • Data collected as part of a joint project among OPPA partners
  • Data collected by one of the OPPA partners, not part of a joint project
Data collected as part of a joint project among OPPA partners

These data are available on the OPPA web-site and anyone who has registered as an OPPA data user can download the data. To register as an OPPA data user, click here.

OPPA data come with a common, multilingual codebook.

Data collected by one of the OPPA partners, not part of a joint project

Partners in OPPA have somewhat different procedures for data dissemination. Here are some guidelines:

GESIS Panel: To access the scientific use file (Standard Edition), Researchers need to complete and sign the data use agreement. To allow students to use the data within the limits of a thesis, the supervisor has to request the data. Upon approval of the data use request, the data archive will provide researchers with access to the current scientific use file via secure ftp download. Please follow the bilingual GESIS Panel Data Access instruction.

LISS Panel: The published LISS panel data can be accessed for own scientific, policy or socially relevant (i.e. non-commercial) research. Use of the data for paid projects for third parties is only allowed against payment. To download the survey data you need to sign a statement confirming that you agree to the conditions.

UAS: The Understanding America Study Data Pages provide access to collected data, accessible for all registered users, unless currently under embargo. (Register here.) Non-registered users may explore the fielded UAS surveys and their individual variables, but cannot view or download data.

KAMOS: All KAMOS survey items and data may be downloaded from here. There may be an embargo on some items, depending on the needs of the researchers. All researchers may use KAMOS data freely, but we ask that you provide us with a copy of any published papers that use our data.
