From CBC News “Census Woes” (after news of Royal Tour comes to an end),
“When the decision to scrap the mandatory long form census was originally made in 2010, many statisticians feared incomplete or compromised data.
As the summer’s final push to collect forms comes to an end, some are suggesting it could be worse than they thought.
Reports suggest that in previous years census workers would call up a household that had not filled out its mandatory long questionnaire, and then pay a visit – or even several – to make sure it was completed.
But now Statistics Canada is accepting incomplete forms without conducting a follow-up.
Don McLeish, president of the Statistical Society of Canada, says partial responses could cause problems in using the data.”
