2011 Census Accuracy needs single address register

The Treasury has published a report on the problems faced by Local Government due to inaccurate population estimates and in particular the impact of highly mobile populations

The comments on addressing are particularly telling
Professor David Martin noted that "One of the single most important underpinning strategies for increasing response rates is to have an address list of the highest possible quality. The 2007 test showed that the best results were achieved by hand delivery of census forms and this approach must be retained for the hardest to count areas.
....
Professor Martin commented that the current competition between the National Land & Property Gazetteer and Ordnance Survey address products was a major threat to the census operation. He noted that each system had different strengths and weaknesses and there was no strategy for integration.
ONS has proposed a comprehensive national address check in the run-up to the census; "yet this entire expensive process would be unnecessary if a single definitive national address list were maintained, in which case much of the address-checking resource could be devoted to other aspects of census data collection and production"
....
The Exchequer Secretary to the Treasury accepted that it was "pretty frustrating" that the Government had failed to make progress in this area. We note that the Government has failed to make any progress in establishing an address register for the 2011 Census. We heard repeated references to the necessity of establishing the register yet were surprised to hear that no business case had been published. We recommend that such a case is prepared engaging all potential beneficiaries. It is unclear whether leadership weakness, lack of legislative means or the financial obligations of the trading fund status have contributed most to the failure. We recommend that the Government consult the Statistics Authority and others to remove any outstanding obstacles to the production of an address register.
And I think many of us would say to that "Hear hear"

Jokes Johnson wants Crime Maps

Well that is what my teenage daughter calls him!

No doubt it will be amusing to have such a well informed and effective mayor for the next 4 years. Is there a get out clause?

Those of us working in the GI community will be looking forward to the impact the new Mayor and his party leader will have on our industry. On 13th February Jokes was quoted in the Guardian
"that he would introduce New York-style "crime mapping", and publish neighbourhood-by-neighbourhood crime figures, if elected London's mayor. "
Brian Paddick, the Liberal Democrat mayoral candidate and a former Met police commander, claimed that Johnson's crime manifesto showed he was "clueless on crime and how policing works".

Apparently Boris then visited the Jill Dando Institute and talked to the team there on the subject.

One might have thought that there are no mapping of crime statistics in London - try googling "crime maps london" and you will find at the top the Metropoplitan Police Service (surprising really Boris) the interactive version needs SVG but is quite informative. Alternatively you could look at the crime section on the London Profiler which has some of the information displayed in a more elegant way.

Ironically the New York CompStat system which inspired Boris is not accessible to the public. However CrimeReports is available for many cities and provides detailed information about the location of crimes (but not in NY).

Now I think we could do better than the current crime mapping sites available in London and not surprisingly I know some very talented people who could help Boris to achieve his objective, that's if it wasn't another joke.

Children of the 60's

There has been a lot of retrospective stuff around on 1968. Paradigm shift or blip in the ocean?

If your football team has drifted into the meaningless zone at the end of the season, you are thinking that "it's only maps" (courtesy SD) or you can't remember what all the fuss was about or you don't even care. Sit back and enjoy Fire
