This paper outlines the demographic characteristics of the Baiga tribe
, one of the most primitive of the aboriginal tribal groups of Central
India. The Baiga population has grown steadily since the first anthro
pological study of the tribe in the 1930s. Age at menarche, age at mar
riage, breast-feeding, and time interval between marriage and first co
nception are natural. There are more females than males. Sub-tribe end
ogamy is common; consanguineous marriage is favoured (34% of marriages
are between first cousins) and marital distance is low (mean 7.1 km).
Though the mean menarcheal age is high (15.2 years), mean age at firs
t marriage is low (16.6 years), giving a long reproductive period.
