I love Halflings but it bugs me that they are the least popular race out there for players. Nobody noticed forever that the "Lucky" attribute wasn't working. In the PHB it states that Humans, elves and Dwarves are a common site but that Dragonborn, Gnomes, Half-elves, Half-Orcs and Tieflings are considered rare and are met with at least curiosity if not suspicion, hostility (tieflings) or fear (half-orcs).
Although going by player choices it almost feels like the opposite is true. Once Dragonborn are released it will be nothing but wall-to-wall Dragonborn paladins as far as the eye can see.
