1979 to 2003 for me, born and raised
I consider Forest Lawn as 'The Hood', so I always thought of Marlborough Park as a suburb of the 'The Hood'
As was mentioned above, it's actually not a bad place considering its reputation, and I personally didn't have a lot of problems. It seems like there is a lot of lower income housing nowadays, as some of the places have become a little more 'run down'. Growing up there, I would feel totally safe; ask someone who didn't and you might get a different answer though.
There is pretty good access to transit in the area (3 bus routes), with a few little strip malls along Memorial Drive. Just a short distance from 36th Street, where there is the LRT, another (smaller) mall, Safeway, some restaurants, etc. Up 36th Street is a newer renovated mall, Superstore, etc.
