This study examines the relationship between ethnicity and fertility in Liberia, within the context of the minority group status hypothesis. The hypothesis argues that minority group status exerts an independent effect on fertility, net of controls for socioeconomic and demographic variables. Using a subsample of women from the 1974 Liberian census, the study examines interethnic variations in fertility by comparing five ethnic minorities--Bassa, Vai, Grebo, Kru, Kpelle--with the majority group, Americo-Liberian. With the possible exception of Bassa women, the findings do not support the minority group status hypothesis. Instead, the findings are more congruent with the alternative assimilationist hypothesis which argues that when sociodemographic differences between majority and minority groups are controlled, their fertility levels should converge. The implications of these findings are explored.
