In 2004 there were fewer than 4 kidney patients on the waiting list for every kidney transplant operation (3.77 to 1) while in 2014 there are nearly 6 patients for every operation (5.96 to 1)

From Mark Perry. 

"At the end of last year there were almost 102,000 patients on the kidney waiting list, a number that far exceeded the number of kidney transplant operations in 2014, slightly more than 17,000. Here’s one way to understand how desperate the situation is for kidney patients: in the last decade, the kidney waiting list has grown by 41,510 (from 60,400 to 101,910) while the number of kidney transplant operations has only grown by 1,100 (from 16,006 to 17,106). Or we can say that in 2004 there were fewer than 4 kidney patients on the waiting list for every kidney transplant operation (3.77 to 1) while in 2014 there are nearly 6 patients for every operation (5.96 to 1)."
