CA does have a lot of illegals because it is a border state and has a very large population. But you need to look at percentages.
There are two numbers, percentage of illegals of total population and percentage of illegal workers in the workforce.
Top five states in descending order(2010):
1. Nevada- 7.2% of pop & 10.0% of workforce
2. California- 6.8% of pop & 9.7% of workforce
3. Texas- 6.7% of pop & 9.0% of workforce
4. New Jersey- 6.2% of pop & 8.6% of workforce
5. Arizona- 6.0% of pop & 7.4% of workforce.
Illegals peaked in 2008 and began to fall so these 2010 numbers are higher than today's numbers. But as the economy continues to improve, the numbers will rise. It is possible that the numbers in Texas has already begun to rise because Texas has been creating a lot of energy jobs.
As for statistics on illegals, they've been BS for years. Even going back to the 1986 Amnesty, when the “statistics” said there were 2 million here to be legalized, but when the numbers came in on how many were granted that Amnesty it was over 3 million.
All the groups, corporations, institutions and governmental agencies paying for or conducting the surveys from which the statistic come are pro-amnesty (even when they pretend neutrality) and as a result we get and under-counted number.
If any form of Amnesty comes to pass, any fool who went along with it based on those statistics will learn how many illegals there actually were and how they were duped by BS statistics.
