Detailed Solution

O negative (O-) is one of the rarest blood types, which is why it is in such high demand. On average, only about 7% of the world's population has O- blood, but this frequency varies significantly based on ethnicity and geographic region.

Here is a general breakdown of its prevalence:

Caucasians (e.g., in the US, Europe, Australia): This group has the highest frequency, with about 7-9% of the population being O negative.
African-American / African Descent: The prevalence is lower, typically around 4-5%.
Hispanic-American / Latinx Descent: The frequency is often lower, around 2-4%.
Asian Descent: O negative is extremely rare in most Asian populations, often found in less than 1% of people.

Because it is the universal red blood cell type and is also relatively rare, blood donation centers always have a critical need for O negative donors.
