The answer is - in same places where they used to be.
In countries like Peru - in general in places with high pop. density in Pre-Columbian era - descendants of natives are majority.
Also in Mexico majority of population are Mestizos - Natives who lived there in Pre-Columbian times with some admixture of European ancestry:

And this is despite the fact that vast majority of Natives died due to European diseases and guns during and after the conquest.
Despite such massive death toll (over 90%), still enough native Mexicans survived to outnumber the European newcomers.
=============================================
In Peru also vast majority of the population are either partially or fully descended from Native Americans.
Just like in Mexico, about 60% are Mestizos, and majority of the remaining 40% are unmixed Natives of the Inca Empire:
And this is also despite the fact that European diseases took an extremely heavy toll among natives of the Inca Empire.

So today 60% of Mexicans are of mixed Indigenous-European ancestry, 30% have unmixed Indigenous ancestry and only 9% are Whites.Mestizo Mexicans are Mexican people who are of mixed European and indigenous ancestry. Mestizos are the majority in Mexico, accounting for 60% of the country's population. An additional 9% of the population is White and 30% are of unmixed indigenous descent.[1]
