answer:I would think so, since they are working for the municiple area (or region/government, if you mean those census workers). It depends on where you live – the laws regarding census. You did not specify which country. In the Canada, census takers are allowed to demand access into gated communities. I think it’s the same for the U.S. as well. There are municiple, province/state/zone and national types of census. I think it’s more important to make sure the census worker is legitimate (ID badges and calling the Census Bureau).
