Padrones/Census - what do letters signify? CC, C, CV, P, CP, CD, etc.

Hi All. I am wondering if any fellow member can help me with this. Looking at old Census (Padrones) of Juchipila and Moyahua, what do the following letters mean? They are placed after each ndividual's name. One or the other is placed, not all at once. It's my first time looking at these records. Thanks!

cc
c
p
cv
cp
cd
s
cs
