Popularity is the total number of Steam reviews, not sales or concurrent players. Activity is the average net daily growth in reviews over the longest stable window of up to 7 days; it requires at least 12 hours of history and data updated within the last 72 hours. It measures discussion volume, not sentiment. Anticipation for upcoming games is measured separately. Missing measurements do not mean a game is unpopular.
