You mention this in the webcast but it bears repeating, the census track populations are aggregated and therefore not naturally distributed. To a layman that aspect of this process may not be so obvious, implying more accuracy in the new population estimates than warranted.
I wonder if adding a dasymetric mapping process to the routine to break down the aggregation could help without becoming too cumbersome?

Regardless, good webcast. I’d be interested in seeing others along these lines… quick and instructive and focused.
Thanks
