Not safer per se, but less likely to come to Voldemort’s attention.
Edit: Chapter 37 also has Quirrell tell Harry that Dumbledore has thorougly warded his parents’ home (though the fact that he is telling Harry this after having crossed said wards does nothing to reassure us, the readers).
“No one’s supposed to know where I am!” said Harry, still keeping the shriek quiet. “Even owls are supposed to deliver my mail to Hogwarts, not here!” Harry had agreed to that willingly; it would be silly if a Death Eater could win the whole war at any time just by owling him a magically triggered hand grenade.
Professor Quirrell was grinning, from where he stood in the backyard beyond the window. “Oh, I shouldn’t worry, Mr. Potter. You are well protected against locating Charms, and no blood purist is likely to think of consulting a phone book.” His grin grew wider. “And it did take considerable effort to cross the wards that the Headmaster put around this house—though of course anyone who knew your address could simply wait outside and attack you the next time you left.”
Is it reasonable to think that Harry’s parents will be safer at home?

It’s an interesting point that the Death Eaters are going to be even more ignorant of the muggle world than the rest of the wizards are.
MoR Voldy shouldn’t need any hand holding to come up with a list of useful leverages against his mortal enemy.
