I agree with most people here. If it's between friends or family I'm sure it would be
more okay, but depending on the scenario. For instance, my family doesn't know how much I paid for Uni, but most of you guys know bc you would understand, they wouldn't. I only tell my friends how much I paid for something if it was an awesome deal. If I pay full price or too much for something i never brag about it.
Now about it being from where you grew up, I grew up in an upper middle class sub burb of Los angeles, but still our house was robbed (not burglarized, but robbed, in which they beat my 80 yr old at the time grandpa), there was a serial killer/rapist in the 80s in my neighborhood, so growing up remembering that, i won't tell anyone what street I live on. Which city? sure, but no more than that. I am just uncomfortable with strangers asking me pretty much anything. I am especially annoyed when guys ask me my nationality. (duh! I'm american!) but that's a whole other thread entirely.
