The given pie charts show a comparison of the percentage of American university students who are capable of speaking languages other than English in the years 2005 and 2015.
Overall, a major proportion of students could not speak any other language besides English in both years. After English, Spanish was the preferred language, which shows a significant increase over the period. Additionally, less than 15% of the total sample size possessed the requisite skills to communicate in more than one language.
An analysis of these charts depicts a decrease in the number of students who could only converse in English. The monolingual population decreased from 45% in 2005 to 30% in 2015. Also, a significant rise in Spanish speakers (bilingual speakers) was witnessed, as they increased from 18% to 29% in the span of ten years. This figure is representative of 25% of the total sample size. Furthermore, the share of the French-speaking population remained constant throughout the years, while the German-speaking population steadily rose from 8% to 10%.
The charts clearly illustrate that speakers who could communicate in another language, except French, Spanish, and German, experienced a rise in numbers from 10% in 2005 to 14% in 2015. Further, individuals who could speak two additional languages observed a slight fall in percentage from 14% to 12% over a decade.
