Is there a consensus on whether it is appropriate to combine Census samples for the sample year? Given that the jurisdictions and variables of interest are the same, can I combine, say a 1% sample and a 5% sample to yield a six percent sample? Someone asked a similar question here: Questions about 1970 Census Data

I figure since the samples are constructed independently, using both of them without replacement (i.e. including people/households that happen to be in both samples) would pose no problem for constructing accurate population statistics.

If this is appropriate, how should I adjust the weights? I’m thinking of performing a weighted collapse by sample/year and then just performing a simple average of all the samples in a year.
