Here’s my issue with looking at the Census Bureau stats-it relies on people to return their questionnaires. How many non English speaking immigrants, legal or illegal fill out Census forms? More so, how many of them would want to if they are violating their lease in some way with the number of occupants?

I agree !

My guess is that Census Bureau underestimates our population growth. And that people’s observations of larger number of immigrants living together are simply not counted.
