700 students in Santa Cruz do Sul learn German

In case you were wondering how many students in Santa Cruz do Sul (a Brazilian city with a lot of German cultural influence) are learning German, apparently it's 700. The article is about the growing importance of German but we do not get the numbers for any previous years in comparison with the 700 learning German now. Total population of the city is 120,000, which would mean about 20,000 students.
