How many kidney transplants in a year do Americans get?

In 2001, there were 15,331 kidney transplants in the US, 9,078 from cadavers, 3,048 from relatives, and 9,078 from unrelated donors. There were 56,598 people waiting for a kidney, and 2,444 people waiting for a kidney and pancreas.

Numbers in the citation are from 2003, not 2001, and the math does not work: the cadavers, relatives, and unrelated donors add up to over 21,000, so probably one is included in part of the other – or it is wrong in the original source (suspect because the two numbers are identical).

The above answer gives a fairly typical year, but just in case you wanted a few more recent figures, here they are (note that kidney-pancreas transplants are not included in these figures, but there are about 800-900 of those/year):

2003: 15,134

2004: 15,999

2005: 16,477

2006: 17,091

2007: 16,629

As you can see, the number usually fluctuates between 15,000 and 17,000 transplants/year (or roughly 16,000-18,000/year if you include kidney-pancreas transplants).
