Swarms
The concept of Swarming Pokémon originated in the second generation games - Gold and Silver. In those games the swarming Pokémon were: Dunsparce, Marill, Remoraid, Snubbull, Qwilfish and Yanma; who's regular appearance rates ranged from 0-1% (rounded).
Fast-forward to the fourth generation games - Diamond, Pearl and Platinum. Swarms are still occuring but the concept has been slightly modified. In these games you must first obtain the National Dex to have access to swarms. Once you have obtained the National Dex from Professor Oak in Sandgem Town head south of Professor Rowan's building to Dawn's house. There you will find her sister who is eager to give you locations of Pokémon in order to help you beat her sister in finishing your own PokéDex.
Be sure to talk to Dawn's little sister everyday as swarms are daily occurences. The list of the Pokémon that swarm in Diamond, Pearl and Platinum is given below.
