HUMAN Surveys stands for Human Understanding Measured Across National (HUMAN) Surveys. The project uses public opinion surveys that are (1) nationally representative of adult populations and (2) freely available. Making comparisons between surveys is difficult and time-consuming because the same variables often have different names, answer scales, and missing values.. We format data to be consistent and maintain a merged database that enables unprecedented comparative analysis of global public opinion.

The aim of HUMAN Surveys is to enable formatting any variable from any freely available and nationally representative survey

Our scripting framework is setup to easily add variables from included surveys and to quickly add additional sources. We continue to broaden and deepen our understanding of populations across more countries to answer important research questions, but also to help others with their own projects. Please contact us if you want to use merged data for collaborative research or publications. Cross-survey data harmonization is time-consuming, frustrating, methodical, and expensive work, but we specialize in maintaining the largest merged database of its kind in the world. Our scripting framework consists of thousands of pages of Stata do files that have taken many years to develop.
