We shall use the term CS broadly to include Computer *and* Information Sciences here. In other words, as long as the unit you are responding for includes a mainstream CS degree. In cases, these are split into different departments, we will include only the CS degree majors data.
The main purpose is to gage the sentiment and reality across the CS departments. To the extent you have a ballpark estimate of the numbers, please use these than trying to get digit-accurate data.
If you have any questions or need more info including access to raw data, please send me an email at email@example.com.
