There are four main differences between the present situation and the time of the Spanish Conquest :
*The number of different ethnic groups has been greatly reduced ;
meanwhile, after reaching a very low levels (which happened at different times
for different groups), the total population is far from having recovered its
former strength.
*At first very much a minority, non-indigenous populations only became an
overwhelming majority from the end of the 19th century onwards (MOREIRA NETO,
1988).
*Indigenous populations only significantly occupy fractions of the area
covered by this report, and often the upper reaches of the major
watercourses.
*As a consequence of the preceding factors, the pattern of land occupation
has altered : from being spread out evenly over the whole area, indigenous
populations are now concentrated in patches. In the process, isolated groups
have emerged, and the rich complex of commercial networks and intensive
cultural exchange was disrupted. Evidence for the complexity of these
relationships has been brought forth by comparing recent archaeological
research with 16th and 17th century texts (Roosevelt, 1989).
*Today, there is continual discrimination against native American Indians,
and great pressure on them to accept an integration which would make them
second class citizens (JIMENO, 1989).
