Non sense! Numbers doesn't add up! They would need to breed like rabbits.
Population of Mexico was around 1 million in 1600, out of which less than 1% was white. As time progressed, the white population increased (as a result of immigration from Europe and high birth rates), while that of the Indians declined. In 1800, the population was 5 million, and the percentage of whites had increased to 18% to 20%. Currently, it is around 10% out of a total population of 120 million.
I think your prior numbers are wacko. Maybe you are counting "deaths attributable ..." but not "births attributable..." or some other statistical error. Also you error in the direction of certainty. There is none.

Note:
The nadir of the demographic disaster is usually placed in the seventeenth-century. I chose 1595 for an end-point, not because I think this to be the nadir of the native population, but to be able to interpolate, rather than extrapolate, comparable figures for the largest number of authors. Nevertheless, Sanders’ figure for the Valley of Mexico is extrapolated from 1568.
