chi-square assumptions with survey data

#1
Hi guys,
I've been asked to run some analyses on some survey data and since it's been a long time since i ran one, I just wanted to check I'm not overlooking some assumptions assoicated with the chi-square test of independence as the text books I've been referring to are quite basic.
The categories are all independent and none of the expected cell counts are below 5 but total count for each variable is often dramatically different (e.g. 155 and 279 or 71 and 361). I can't find anything suggesting that this is a problem, but it's just not sitting right.
thanks

The variation in the total will not be an issue (Since none of the expected cell counts are below 5). The variation will be accounted in the expected value calculation.
