Hi Census power users-
This is one of those things that deserves repeating...
Census Bureau is asking for descriptions of how you use - and why you need - specific
tabulations of the 2020 Census<https://www.federalregister.gov/d/2018-15458/p-19>
This input will shape the SF1 and SF2 products that will be available 2+ years from now.
They have recently re-opened the comments period. The latest Fed Register
extends the comments deadline
to November 8.
Comments have already been submitted by State Data Center agencies from Alaska, Arizona,
California, Colorado, Mass., Michigan, Nevada, North Carolina, and Wisconsin. You can see
It's public info!
Why your comments matter: Differential privacy protection.
The Census Bureau will modify some Decennial SF1 and SF2 tabulations that were previously
available - and they could reduce the details available for census blocks (the most
detailed, localized geographic level).
Unpacking what I've heard about this, I believe the Census Bureau is considering a
range of possibilities. They are really asking:
* What tables or variables are mandatory and must be precise to the nearest 1 person?
* What tables or variables can allow for "perturbing" or "noise
infusing" of data cells - typically through block-to-block swapping of individual
microdata records - in order to protect privacy?
* And what tables that were previously published for census blocks can be "clawed
back" - and be tabulated only for larger geographic units.
Some background information on differential privacy protection can be found in recent
presentations by Census
Give it some thought - and get those comments in.
