Which is not true about the population of central america?
most of the people of east asian and south asian descent live in honduras.
ninety percent of the people living in costa rica are of european descent.
mestizos are a large part of el salvador’s population.
central american indians make up more than half of the population in guatemala.

The correct answer is "Most of the people of East Asian and South Asian descent live in Honduras.".

The majority of the people in Honduras share the same ethnical background as their Salvadorian counterparts. In other words, the majority of the population are mestizos. However, there is a small group of people (less than 1% of the population) which are Northern African descendants and are predominantly white.
