Census chief defends surge in SA birth rate
Statistician-General Pali Lehohla - and a panel of experts - yesterday assured South Africa ns that Census 2011's information was reliable and accurate .
Released earlier this week, the census recorded a sudden surge in fertility across the population that defied expectations and large-scale internal migration. This had resulted in Gauteng's population increasing by more than a third and the Western Cape's by 29% in a decade.
Two demographers at the University of Cape Town, Tom Moultrie and Rob Dorrington, criticised the data and methodology employed.
Both felt the results were rushed through. They were part of a group of experts who had to edit the census results before they were released on Tuesday.
Lehohla - dressed again in his trademark yellow suit - denied the release was rushed.
He saidthere was no reason to "keep the numbers in the fridge" any longer.
Howard Gabriels, the chairman of the Statistics Council, which has an oversight role, said that Moultrie and Dorrington's concerns were being taken seriously.
The council, he said, took the opinions of several experts into account and "did not take the decision [to sign off on the census] lightly".
Lehohla said Dorrington and Moultrie had ample opportunity to study the data, but that the "two eminent gentlemen" were too busy with other projects.
The panel assembled by Stas SA at the briefing yesterday made presentations asserting that the information on the migration and fertility rates is sound.
They argued that the findings of the latest census were consistent with the information collected in the 2001 census.
