The planter group (those who held 20 or more slaves) made up under 4% of the adult white men in the south, held more than 1/2 of the slaves and produced most of the cotton and tobacco and all of the sugar and rice, thus most slaves lived on large plantations.

That was common. If you owned a Planation, it usually required a large work force to farm it. Senator John S. McCain (presedential candidate for 2008) had an ancestor named William Alexander McCain who owned a planation and 52 slaves. This has been verified by National Archive records and Census Records of Mississippi in 1860.
