Sexed Intermarriage Drives Demographic Absorption

Partnering and childbearing patterns are not symmetric across sexes and classes: which sex from which group mixes with which other group can determine whether a population is absorbed or persists as a distinct people. The article uses CDC natality figures (via BAP) to show that directional reproductive mixing in the U.S. (e.g., educated Asian mothers having White fathers at nontrivial rates, but the reverse being rare) produces asymmetric assimilation pressures that Canada’s concentrated Anglo/French cores avoid. — If reproductive mixing is systematically directional, it changes projections for ethnic persistence, political representation, and the feasibility of large political unions or assimilation policies.
