Alternative way to set property?

I've previously set a property in a Django model class using property() and it also works.

I'm wondering if it's possibly an outdated way of setting the property and I should re-factor using @property? The code works great, but I was just curious about the difference. Here is the relevant bit:

class Person(models.Model): 
    gender = models.CharField(max_length=8, choices=GENDERS, default='')
    birthdate = models.DateField(max_length=25)
    tobacco = models.CharField(max_length=5, choices=YES_NO, default='NO')
    household = models.ForeignKey(Household)

    def _age(self):
       Returns the age from the date of birth
       now = datetime.datetime.now()
       return now.year - self.birthdate.year - ((now.month, now.day) < (self.birthdate.month, self.birthdate.day))
    age = property(_age)
