It had become more common in Orlando, too, but many of those robberies seemed to target illegal immigrants - who were extremely unlikely to call police.
I moved back to Illinois from Florida in 2007; there was a noticable uptick in home invasions in the couple of years before I left though. Mostly middle class areas. The HI was typically the result of someone leaving a garage door open at night and the bad guys entering through the garage; or someone out in an open garage late at night confronted by the bad guys.
Live by these two words: Home Carry
Something good to know is also your typical area LEO response time. I had to call the cops for the first time sunday night; there was a drunk guy who could not stand in the lobby of my building. Cops were there in about 2 mins; I was rather impressed.
