The answer is mestizos. About 70% of Paraguay's population is comprised of mestizo people.

According to the Country Profile of Paraguay released by the United States Federal Research Division of Congress in 2005, about 95 percent of Paraguayans classify themselves as mestizo. The rest of the population is made up of unassimilated peoples and immigrants.

I hope this helps! :)
