I have geospacially clipped census blocks into a new geography to estimate the population for the new area (new area/old area * population estimate).
Is there a method to calculate the new margin of error for these new estimates?
Hi!
To calculate margins of error for derrived estimates (such as when you group across geographies) see Chapter 8 of the Handbook
https://www.census.gov/content/dam/Census/library/publications/2018/acs…
I don't think the handbook--by this omission--is intentionally trying to comment on the appropriateness of working with partial geographies. More to the point, the statistical principles guiding how to…
Yes, that is the correct link for Geocorr (all versions).
As for that R package, it seems very out of date (still using Geocorr 2014 with 2010 geographies) and also fairly limited -- it includes only 11…
Since the block populations come from the decennial census they have a 0.0 MoE. If you assume that the population is uniform across the block then both the estimate and the MoE would scale by the same factor ( new_area/old_area ) * MoE. I can't think of a way you could quantify the error associated with the fact that it is unlikely that the population is uniformly distributed across the block. You might be able to find a research paper on this.
Best,
