It's entirely cultural. These days most couples end up far away from both sets of parents, back in ye olde days couples were usually from the same town(or at least nearby towns) so they ended up close to both. It's entirely up to you and your husband. You have to consider if he has an established job, will he easily be able to get a new one that pays well if you move. Also you have to consider housing, both in terms of price and in terms of location(access to Sacraments, good neighbourhood, proximity to amenities, etc.). Then of course, the health of your respective parents. If any of them are in need of minding then you'll probably want to live fairly close, but they could also move themselves if necessary(my grandfather for example moved in with us a few years after his wife died, he was still of good health but just in case. He actually made my parents' jobs a lot easier by helping with minding/collecting us, groceries, etc.).
