The disappearance of the white race caused by sub-replacement fertility among all white populations and simultaneous mass immigration to formerly all-white or majority-white countries.

An example is the United States of America, where the white population has been in relative decline for over 50 years, from nearly 90% to under 63% of the population, and will soon be in absolute decline. Even in many European countries, the ancestral homelands of the white race, the white population is now in absolute decline.

White extinction is the end goal of the alleged white genocide conspiracy.
