Geographical variation and evolution of tertiary sexual equilibrium in the province of Jujuy (Argentina).
The tertiary sex ratio, as measured by the masculinity index, was examined in four regions of the Province of Jujuy in north-west Argentina over a period from 1869 to 1991. The results showed that inter-regional, as well as age group differences in MI existed which could be related to changing social and economic conditions in this area over the last two centuries.
