Note to Users

We recommend that researchers become familiar with the CSES design, units of analysis, documentation, and dataset weights before beginning their investigations. For instance, while the set of respondents appearing within each election study represents their respective nations, the group of nations that appear within CSES is not a random sample of countries worldwide. Furthermore, while many election studies include 1,000 or so respondents, other election studies may consist of over 10,000 respondents. Some nations will have studies of more than one election in a CSES module, and occasionally there will be two independent studies of a single election. Last, some election studies include oversamples of specific subpopulations or would otherwise benefit from use of the included weight variables. We hope you find our website and documentation useful as you proceed with your work, and welcome any questions or suggestions you have.
