Almost all that information is available from other sources.
The NHS records all birth and vaccination records. Local
authorities know where all the kids live, who their parents
and or guardians are.

HMRC have employment, company and VAT data. Lots of it.
The police have their PNC at Hendon.
The Security sources in NI used to have details of every house
including even things like, colour of sofa and curtains. All useful
stuff for interrogating suspects.

Everything that government statisticians and planners need to
know can be now be collated simply by doing a huge data trawl
on the existing government and 'private' databases. 100 years
ago this rich source of data didn't exist.

One big problem with using lots of different databases like this is matching
the entries that relate to the same person. That's why it would be so much
better if everything required one common ID (NI number) which would show
that John Smith on the utility company database was the same as John Smith
in the DVLA database and the same as John Smith who was born on date at
location with mother's maiden name of name and the same as John Smith
who works for company and earns salary.
