Yeah, some places are better than others. When I was waiting for a transplant, I lived in the western United States. I shared an organ distribution region with California. My docs told me: "That sucking sound you hear is all the needed organs going to California." Ha! I waited 2.5 years for a transplant.
Varies by state because of details of organ donation laws, religious makeup, quality of healthcare. Blue states tend to have fewer donors (seat belt laws, gun laws, more social safety net). High concentration of hospitals is generally bad (car accident victim on the Mass Turnpike gets rushed to one of a number of world class hospitals, lives, not a donor). So Boston bad. New York worst state in US: need an organ in NYC? Relocate while you can.
Midwest and southern generosity typically drives higher donation rates. Neighboring states may draw organs from your state.
Transplant hospitals that do many cases get really good at it, and have enough experience that they will use organs other centers will reject. My liver was rejected by at least one other transplant center before it arrived in Indianapolis. (They let me see it before surgery. How cool is that?) So think twice before ruling out an organ just because someone else said no.
Blood type, physical size, and exact timing of things can cause lucky breaks.
A combination of lots of people killing themselves(usually in auto accidents) plus many people who need a liver being ineligible to get one due to alcoholism/drug addiction/other health problems.
The reasons are morbidly fascinating and too detailed to go into here.
