For native speakers, there is also the level of education and the contexts they use it in that can influence their vocabulary. I know a lot of Spanish speakers, both heritage speakers and those who grew up in Spanish a speaking countries. Heritage speakers often are educated in English and mostly use Spanish at home and in social situations, but are more comfortable in English for other topics. Lots of my coworkers who grew up in Spanish speaking countries have pretty limited formal education. In either case, they often don’t know the Spanish terms for technical, scientific or political contexts, and will just use the English word, even in Spanish.

This doesn’t mean that English has a richer political or technical vocabulary than Spanish, but it does create a chicken and egg situation in certain contexts. Why bother to learn and use the Spanish term if the English term is already more widely known, especially if it isn’t a topic that would lend itself to popular publications and discussions outside of industrial or academic contexts? Even in Spanish speaking countries, the increasing dominance of English internationally can result in highly educated people in these countries being pressured to publish in English, further reducing the number of occasions one might have to use these terms in Spanish.
