Data source: https://freedomhouse.org/content/freedom-world-data-and-resources The full code used in this post is available here.

The SDR project will develop a website for browsing, subsetting, downloading, and visualizing data from the SDR project. This website is currently under construction. Meanwhile, I made a Shiny app with basic functionalities of the future on-line browsing and subsetting tool (also serves as its mock-up): https://mkolczynska. https://martakolczynska.com/post/sdr-exploration/ Thu, 02 Aug 2018 15:41:00 +0000 https://martakolczynska.com/post/sdr-exploration/ Introduction Downloading the SDR data Exploring SDR: availability of variables by project Exploring SDR: availability of variables with different formulations Identifying surveys containing selected variables Subsetting the Master File Country coverage plot Combining data from different survey projects creates new opportunities for research, alas, at the cost of increased volume (obviously) and complexity of the data. The Survey Data Recycling project created a dataset with data from 22 international survey projects.
