The goal is to determine (i) which dataset best represents population demographics; (ii) in what parts of the world the</div><div>datasets are most representative of actual populations; and (iii) how to weight the datasets to provide more accurate representations of underlying populations. The paper finds that the two datasets represent very different populations and that they correlate with actual populations with values of r = 0:60 (social media) and r = 0:49 (web-crawled). Further, Twitter data makes better predictions about the inventory of languages used in each country.</div>
