Parliamentary Voting System and Constituencies Bill

Lord Rooker Excerpts

Wednesday 19th January 2011 Lords Chamber

[Lord Wallace of Tankerness]

I cannot give a technical answer, but I can say that they are produced by the Office for National Statistics at the local authority level and that they are estimates of change. I do not have the psephological—I am sorry, I meant the statistical—basis for this.

[Lord Rooker]

The Office of Population Censuses and Surveys used to do the same job and was the guardian of data on births, marriages and deaths by geographical area. To my certain knowledge, it used that data in Birmingham to update the figures. The health authority used those OPCS figures for births, marriages and deaths. It did not track the population, but it had a base of information that could be used for an annual update. That is what I recall.
