Yesterday the NRS published their updated 2011 Census Output Prospectus (pdf). Some key dates for your diary are:
1) 17 December 2012: First Census population estimates by 5-year age bands and sex for Scotland, total population estimate for each council area.
2) March 2013: Population estimates by five-year age bands and sex for Scotland and each council area. Household estimates for Scotland and each council area.
3) May 2013: Population estimates by single year of age and sex for Scotland and each council area.
4) Summer 2013: Key and Quick statistics tables; Scotland level population estimates by single year of age and sex, Census Profiles; Population and Household estimates by postcode and Geography products.
5) Autumn 2013: Local Characteristics tables.
6) Winter 2013: Detailed Characteristics tables.
(Draft table design are available from here)
It is expected that as Scottish data is made available detailed UK-wide Census statistics will be produced by ONS – timings of these are not currently available.

Do you mean GB-wide Census statistics?
Still waiting for NISRA to reveal their publication timetable.
Hi David – latest we heard was that NISRA were ‘insync’ with ONS but we haven’t had a specific update from them. I expect ONS will wait until they have consistent (unrounded) data before producing UK tables; so this may have to wait until March next year and the unrounded NRS data.
