Southern Cone: Paraguay vs. Argentine NW/Cuyo starting in 1700s-early 1800s

Nov 2010
In and around present-day Argentina, the most heavily populated and/or traditionally Hispanic areas up until the late 1700s and early 1800s were Paraguay (east of the Paraguay River), the Argentine Northwest (i.e. Salta, Tucuman, Santiago del Estero, Cordoba, etc.), and the Cuyo (i.e. Mendoza, San Juan, and San Luis). What I'm wondering about each of these three regions are as follows:

1) How many peasants or campesinos currently live in each of Paraguay, NW Argentina, and the Cuyo - in both absolute and relative terms?

2) How many mestizos and pure Indians lived in each of these regions in the 1700s and early 1800s - in both absolute and relative terms?

2a) Is the share of mestizos higher in NW Argentina than in the Cuyo?

3) How many immigrants from Europe and elsewhere came to each of these regions in the late 1800s-early 1900s?

Basically, what I want to know is whether Paraguay has been more traditional/Hispanic in these regards than the Argentine NW and the Cuyo, or the other way around.
