Just released by the Transportation Research Board was the proceedings
of a national conference on applying Census Data for Transportation
Planning. http://onlinepubs.trb.org/onlinepubs/circulars/ec233.pdf
Last November, well over 100 transportation data users came together in
Kansas City Missouri to share experiences with the use of Census data,
including new techniques for integrating different data sets for use in
transportation planning and decision making. The conference provided an
opportunity for participants to discuss opportunities, limitations, and
challenges involved in using Census data, data available from the
private sector, and data from global positioning systems and other
technologies. Finally, participants were able to discuss research and
training needs associated with applying Census data and data from other
sources to transportation planning and decision making.
I encourage anyone with an interest in data and transportation planning
to take a look at the conference proceedings.

Transportation Planning Consultant

All,
Thank you to all who submitted comments seeking to update the rules for
block group and census tract delineation for the 2020 Census Participant
Statistical Areas Program (PSAP). The transportation planning community’s
submissions were substantial and the Census Bureau is interested in finding
a solution to our needs while working within their own limits to ensure
standards for survey data quality and privacy concerns.
The Census Bureau has distilled comments relating to combining
residence-based and workplace-based delineations into three options and has
asked us to give feedback on how workable these options may be. Two of them
seem more plausible for the Census Bureau’s final ruling on 2020 PSAP
criteria, but may be more limiting than transportation planners would
desire. We are seeking people willing to test out these options with their
own geographies. We’d like to know whether one option is more workable or
preferable than the others--and why. Do some options work better for
single-use geographies but not as well for mixed-use? Do they work better
or worse than how your TAZs are currently delineated?
We will use this survey form (https://goo.gl/forms/SgHrqne2NhGjUsEr2) to
collect comments about folks’ observations when testing the options. Time
is limited, as the Census Bureau has only this summer to finalize how PSAP
2020 will work. *If you’re willing to test one or more of these options in
a sampling of your communities and workplaces, we must receive your
feedback by June 20.* If you’d like to view others’ comments before or
after submitting your own, scroll to the bottom (leaving the form blank)
and press submit. You will have the opportunity to see your own answers
after submitting and to revise your response, if desired.
One of the key differences--highlighted in the options below--between the
needs of the ACS and the CTPP special tabulation is that the ACS does not
report workplace geography below county subdivision or census designated
place. CTPP will continue to seek workplace and journey-to-work flows by
tract--and in post 2020 releases--block group. It may be desirable for CTPP
data quality to see workplace-based geographies with employment counts high
enough to get a reasonable samples of workers at smaller geographies, but
the Census Bureau has no need for ACS reporting to see block groups meet a
minimum threshold of employment--especially when it comes from a local
source they have no way of verifying. In other words, the CTPP Oversight
Board’s recommended comments of a minimum threshold for employment for
block groups and tracts (on par with population minimum thresholds for
those geographies) may be good practice for delineating to get better
workplace data in the CTPP, but may not be necessary from the Census
Bureau’s perspective.
Please try these criteria for delineation on your current geography and add
your comments to the google sheet
*Option A: Employment thresholds where population or housing is not present*
This scenario gives priority to population or housing units for delineating
standard block groups (min: 600 people or 240 housing units; max: 3000
people or 1200 housing units) and tracts (min: 1200 people or 480 housing
units; max: 8000 people or 3200 housing units). If an area was devoid of
population or housing, that area could be delineated by a minimum threshold
of 600 employees per block group and 1200 per tract. Special Use block
groups and tract criteria would stay the same (Within an urban area: min. 1
square mile; Outside an urban area: min. 10 square miles).
*Option B: Only need one threshold met--population, housing or employment*
This scenario allows for some presence of population or housing that may or
may not meet a minimum threshold, as long as it meets an employment minimum
of 600 jobs in block groups or 1200 in tracts. Conversely, it allows for
population of 600-3000 in block groups or 1200-8000 in tracts without
meeting a 600 or 1200 job threshold, respectively. Special Use block groups
and tract criteria would stay the same. This is seen as a very unlikely
option from the Census point of view because it would degrade resident
sample sizes to a point where disclosure would be a real concern.
*Option C: Special use block groups and tracts have no minimum area
criteria - no employment thresholds*
Rather than seeking employment thresholds, removing the square mileage
criteria of the special use block groups and special use tracts would allow
agencies to define non-residential land in whatever way they want. If there
is no presence of population or housing units, non-residential land-uses
could be carved up by block group and tract boundary rules (see below info
on boundary rules below). Those concerned with achieving a minimum sample
size of workers at workplace may opt to consider employment counts while
delineating, but would not need to report this as justification for where
proposed tract and block group boundaries are delineated. Residential areas
would follow current standard block and standard tract population/housing
unit thresholds.
*What PSAP guidance says on boundary line features:*
For tracts, beyond using governmental (County, reservation or MCD [where
applicable]), or “permanent natural and constructed features, such as
roads, shorelines, rivers, perennial streams and canals, railroad tracks,
or above-ground high-tension power lines”, the federal register allows:
“boundaries of large parks, forests, airports, penitentiaries/prisons,
and/or military installations, provided the boundaries are clearly marked
or easily recognized in the field in imagery and on the ground.” Barring
all that, it says: “When acceptable visible and governmental boundary
features are not available for use as census tract boundaries, the Census
Bureau may, at its discretion, approve other nonstandard visible features,
such as major ridgelines, above-ground pipelines, intermittent streams, or
fence lines. The Census Bureau may also accept, on a case-by-case basis,
relatively short stretches of boundaries of selected nonstandard and
potentially nonvisible features, such as cadastral and parcel boundaries or
the straight-line extensions or other lines-of-sight between acceptable
visible features.” More details here:
https://www.federalregister.gov/documents/2018/02/15/2018-02625/census-trac…
For block groups, the same can be said, with the addition that any block
group “nest” within its “parent” census tract. More details here:
https://www.federalregister.gov/documents/2018/02/15/2018-02624/block-group…
We've very appreciative of any feedback you can give on this important
matter. Thank you in advance!

I believe the SDC leads/state demographers are compiling these lists for
their states. I know they were asked to do so, and I had a conversation
with Eric Guthrie here in Michigan about PSAP in the SEMCOG region.

We're looking for PERSONAL income (not HOUSEHOLD income) of persons who bike to work.
NHTS and Census apparently only have household income.
Any idea where to look for this?

Hi All,
A friendly reminder that the comment period for the federal register notice closes May 16th Please head on over to https://www.federalregister.gov/documents/2018/02/15 to review the proposed criteria and submit your comments. Comments can be emailed to geo.psap.list(a)census.gov<mailto:geo.psap.list(a)census.gov>
The CTPP shall submit the following comments for "Block Groups for the 2020 Census-Proposed Criteria" (83 FR 6937) and "Census Tracts for the 2020 Census-Proposed Criteria" (83 FR 6941):
The Census Bureau should
* Determine minimum employment thresholds needed to have an equivalent level of sampling validity as population thresholds have for both the block group and census tract levels;
* If population sample size requirements are a reasonable sample size proxy for employment sample size needs, the minimum employment thresholds could be the same thresholds as population: block group - 600; census tract - 1,200;
* Have no maximum employment threshold;
* Add these employment thresholds as alternative criteria of the standard block group type or census tract type;
* Allow PSAP participants to use their own local employment data to justify delineating within these thresholds;
* Allow employment number to be reflective of 2010 to current year data, or projections for growth by approximately 2020.

Subject: [CTPP] CTPP Policy changes on small geography
Importance: High
Hello CTPP!
The Census bureau has proposed criteria for geography for the 2020 census in the Federal Register. The criteria is open for comment until May 16, 2018. Click here: https://www.federalregister.gov/documents/2018/02/15 and scroll to Census Bureau for the proposed criteria most relevant to you! (Census Block Groups, Census County Divisions and Equivalent Entities, Census Designated Places, and Census Tracts).
The CTPP oversight board strongly urges you to read the notices, respond as appropriate, and get involved in the Participant Statistical Areas Process (PSAP), as custom small geography in the CTPP tabulation will be discontinued after the next tab. Please see attached memo.
