Hi Maisie Yes *had to* but like all questions there was no checking done to verify if it was a true statement The instructions actually state that if the informant does not know the exact income they should give the approximate income as best as they know it The later census have become simpler and less obtrusive as the civil liberty bods get up in arms if they ask some questions, they do like the sound of their own voice though and will question every mortal thing just because they like to make life difficult for everyone else Nivard Ovington in Cornwall (UK) On 13/10/2013 21:12, Maisie Egger wrote: > Ah-ha. > Looked up the US Census for 1970 and apparently one HAD to state one’s > income...scroll down to #40. > https://usa.ipums.org/usa/voliii/items1970.shtml > However, I don’t remember answering so many questions otherwise.
