We maintain three data warehouses to enable research at different levels of analysis, creating customised target variables, and flexibility for many types of studies. The first is micro-level individual data and includes millions of respondents from most countries in the world. The second contains macro-level country-surveys scores, which are created by averaging answers from respondents in each national survey. This is useful for methodological studies and making comparisons between surveys because there are many cases where multiple surveys have been conducted in the same country in the same year. The third data warehouse contains country-year scores, which are created by averaging all overlapping country-survey scores. This creates a single score for each country in each each year, making it useful for time-series analysis and studying historic trends.

Analyze 10 million survey respondents across 170 countries from the 1960s onward to conduct unprecedented original research.

The work of formatting and harmonizing variables is time-consuming and in some instances highly complex. We do so as needed for different research projects, which means that the progress of selected variables differs across the sources. With time and by working with to others we aim to continue expanding the scope and breadth of included variables, but the following lists summarize the current state of progress.
