  Are Brazilian developers less likely to have a contribution accepted than
their peers from, say, the United Kingdom? In this paper we studied whether the
developers' location relates to the outcome of a pull request. We curated the
locations of 14k contributors who performed 44k pull requests to 20 open source
projects. Our results indeed suggest that developers from countries with low
human development indexes (HDI) not only perform a small fraction of the
overall pull requests, but they also are the ones that face rejection the most.
