Used here as a reference parameter to determine the number of students or first-year students.
Differing time concepts are used when collecting data on the annual cycle of studies to differentiate
between students and first-year students.

In the case of students, the annual figure is equal to the number of students in the winter
semester. In Wissenschaft weltoffen, the students of the winter semester 2010/2011 are defined
as the students of academic year 2011.

For first-year students (students in their 1st semester in higher education academic or 1st
semester in academic studies) is defined as follows: the sum total of first-year students in a
summer semester and in the subsequent winter semester equals the number for the year. The
first-year students of the academic year 2010 are the first-year students of the summer
semester 2010 and of the winter semester 2010/2011.
