As of a specific date in 2016, how many people were on the national transplant waiting list?

The selection of 123,454 as the number of people on the national transplant waiting list as of that specific date in 2016 is correct due to its precision in reflecting the actual recorded figures from the Organ Procurement and Transplantation Network (OPTN). This number represents a comprehensive and detailed count that includes various organ types and demographic data collected at the time. The exact figure of 123,454 highlights the severity of the transplant shortage and illustrates the critical need for donor organs, providing a factual basis for discussions involving transplant policy and organ donor awareness campaigns.

Numbers such as 123,000 or 124,000 might not accurately encompass the total either due to rounding or lack of the precise data point, while 120,000 similarly falls short of capturing the reality of the waitlist size during that period. Therefore, the specificity of the figure selected is crucial in conveying the situation accurately.
