I've only used this just once, paid the one off charge to access one address and after 20 years of research I actually discovered my 2xgreat grandfathers date of birth. This census contains dobs which was a pleasant surprise. What it didn't show was the place of birth (or if it did I couldn't see it) as in previous census which would have been useful in this case. But I did see everyone visible (lots of 'locked'records on two pages so also saw the details for other relatives that lived in the same street.
For me it was worthwhile for that dob alone (not that I can find an actual birth registration!) but it revealed less than usual census because of the living/post 1915 rule. As my lot were Londoners I could have found as much information (and have) through the electoral registers.
To think that London, or anywhere else for that matter, does not belong to any one demographic
