The official genealogy site of the 1901 Census for England
and Wales is on-line at
http://www.census.pro.gov.uk
It includes records for all the old Jewish neighbourhoods
such as Spitalfields, Whitechapel, and Mile End.

You can search by name, or by address, and see summary
information for each record. Unfortunately, there is
a charge to access the detailed records -
75p (US$1.20) for a document image, and 50p (US$0.80) for
a text record, with a minimum of £5 (US$8) per session.

I found my grandparents with no problem! Now I know where
they lived, and what they did.
