A country-by-country build log
The Small-Area Global Elections dataset covers 134 countries at the smallest unit that each electoral authority publishes, which for most of them is a polling station of a few hundred voters. Building the dataset was almost entirely a manual process that spanned several years. Using timestamped files, I can roughly recover the timeline for each country's build process.
Built from the dataset tree as of . The dataset itself is at the project page and on Harvard Dataverse.
