FOR IMMEDIATE RELEASE: FRIDAY, MARCH 1, 2013
Public Information Office
***CENSUS BUREAU MEDIA ADVISORY***
Commuting Products to be Embargoed
The U.S. Census Bureau's Public Information Office will offer an embargo
period next week for members of the media to view a series of commuting
products. Statistics will be available for every county in the U.S.
showing the number of workers that commute in or out and which counties
those commuters travel to and from. Additional reports and tables, based
on statistics from the American Community Survey, examine U.S. residents
traveling across county and state lines to work. Specifically, the
products present U.S. workers who have commutes of 60 minutes or longer
and workers who have "mega commutes" of at least 90 minutes and 50
miles. Statistics will also be available for every county in the U.S.
that show the number of workers that commute into or out of the county
and which counties those commuters travel to and from.
The reports and tables will be posted to the Census Bureau's embargo
site at noon EST Monday, March 4. The public release will be at 12:01
a.m. EST Tuesday, March 5. Wire and distribution services are prohibited
from distributing embargoed news releases and data files to subscribers
before the public release date and time.
If you are interested in scheduling a radio interview on Tuesday, March
5, please contact the U.S. Census Bureau Public Information Office at
ctpp-news mailing list
Attached is the press release on some newly released Census Tables that
may be of interest regarding daytime populations.

In our review of ACS PUMS, we have found what we think is a workplace
coding problem and concerned that the coding error will be carried forward
into the CTPP. The Census workplace coding problem was identified
comparing change in employment estimates between 2000 and 2010 from BEA and
BLS compared to Place of Work (POW) coding in Census long form/ACS over the
same 10 year period.
2000 Census to 2010 ACS
It is important to understand that Baltimore City is an Independent City
and is NOT included in Baltimore County. Baltimore City is a
We are wondering if other metropolitan areas are finding results using the
ACS workplace coding that are divergent from other employment sources.
We are wondering if our problem is mostly due to the city and county having
the same name, or if there is some other issue.
Detail results from the Baltimore MPO trend analysis follows.
The Baltimore MSA in 2010 contained 2.7 million persons within six
political subdivisions (five counties [Anne Arundel, Baltimore, Carroll,
Harford, and Howard] and one independent city [Baltimore City]). All six
political subdivisions have a 2010 population in excess of 100,000,
allowing for designation of Public Use Microdata Areas (PUMAs) within each
political subdivision for the Baltimore MSA. Our concern in POW coding
relates to Baltimore County and the independent City of Baltimore.
(Baltimore City is NOT an incorporated City within Baltimore County.
Residents of Baltimore City are NOT residents of Baltimore County. The
independent City of Baltimore’s political status is equivalent to a county.)
Bureau of Labor Statistics (BLS) nonfarm annual estimates for employment
within Baltimore City was reported to have decreased 13.8% (408.4 to 352.0
thousand jobs) between 2000 and 2010.
Bureau of Economic Analysis (BEA) table CA25N was used to estimate
employment within the Baltimore region’s six political subdivisions. BEA
reported a -13.4% reduction in Baltimore City employment between 2000 and
2010. Job growth between 2000 and 2010 was estimated at 13.3% for
An analysis of the 2000 decennial Census long form and 2010 ACS POW coding
report contradicting trends compared to those reported in the BEA and BLS
estimates. Census 2000 to 2010 POW trend seems reasonable compared to the
BEA trend for Anne Arundel, Carroll, Harford and Howard Counties.
Baltimore County POW coding results in a 3.9% growth in Census reported
primary job locations and Baltimore City Census POW coding results in a
2.2% growth in reported primary job locations. Our concern is that during
the review of addresses that do not geocode automatically Baltimore City is
receiving Baltimore County reported primary POW locations.
We are hoping other urban area analysis of Census POW coding can help focus
further analysis. We feel there is an allocation/gecoding issue but are
unsure if the error is related to Baltimore City’s status as an independent
city or confusion in having a county and city with the same name.
Looking forward to hearing from others on analysis of POW coding.

I have not checked other campus area population counted by census 2010 but
this number is very large (and hope not double counted by their parents),
And there are only 3 houses on the campus area based on the census block
result, I know: 1 president's house, 1 chapel , and... don't know the 3rd
but there are 25 dorms not counted. And the house location is not right, or
a block with population data but no house... as my boss said, a lot of
people live at MSU tunnel.
If attachment is not allowed: zip code 48825, MSU campus area on census
2010, total block population: 10688, number of houses:3 .. and based on
campus data students live on campus (residence hall) is about 15000 (the
nation’s largest single-campus residence hall system !)

Rather than summarize all previous listserv emails and off-line discussions on this topic, I will instead present the latest set of desired changes to the three “rail transit” categories:
__ Rail: light rail, streetcar, or trolley (a change from the current “Streetcar or trolley car”)
__ Rail: subway or elevated (a change from the current “Subway or elevated”)
__ Rail: commuter or long-distance railroad (a change from the current “Railroad”)
I can’t state these are “official U.S. DOT recommendations” just yet, but we will need to either come to this decision in early June or identify something else (or just “give up” again, which is not what anyone of us want to do!) Other changes (e.g., additional transit and non-transit mode groups, some type of “list all modes used” question, a switch from the “usual” specification, etc. etc.) do have merit, but there is a strong consensus that adding complexity to a U.S. DOT recommendation could jeopardize the opportunity for ANY changes to be subjected to a formal “content change” test. I should also note that even if this is approved for a formal “content change” test, we don’t yet know, of course, the findings from those tests.
If you work for a transit agency that operates multiple rail modes (or at least a “light rail” mode), or an MPO that covers a region with multiple rail modes, and you see value in your future planning if these changes were implemented, please send me an email (Ken.Cervenka(a)dot.gov<mailto:Ken.Cervenka@dot.gov>), or give me a call early next week (202/493-0512) and I will let you know how your interests can be recognized.
For those who may want to review the full ACS question, with the proposed changes to the three “rail transit” modes included, I am showing below.
31. How did this person usually get to work LAST WEEK? If this person usually used more than one method of transportation during the trip, mark (X) the box of the one used for most of the distance.

__ Rail: commuter or long-distance railroad
__ Worked at home

p.s., I am sure everyone knows that Memorial Day is Monday, and let’s not ever under-estimate the value of the personal sacrifices that have been made.
The loss of Census sampling (today the ACS), the Census of Agriculture, the
Economic Census, etc., would be disastrous in so many ways I find it hard to
believe anyone - even deeply partisan politicians - would advocate their
demise. The small gain to the Federal government's bottom line would be
undercut by huge (albeit hidden) losses to the private and public sectors.
The loss would be especially acute for small businesses.
1. There can be no serious doubt that Federal sample products leverage
their cost many times over in benefits to the economy. The benefits are so
widespread, and so implicit, that the burden of proof must lie on anyone
attempting to undo Federal data-gathering. And they will find no such proof.
2. The U.S. government has, in the past, set the world standard for
data-gathering. The widespread availability of free, accurate data runs
hand-in-hand with upholding the standard as the world's foremost democratic
society. To surrender the ACS and related products is not just a bad idea,
it is a retreat from leadership.
3. Answering ACS forms, or any other Federal questionnaire, is a
matter of personal responsibility. To survive, democracy depends not just on
the protection of personal rights; it also demands a sense of responsibility
by its citizens.
4. I have never heard of anyone going to prison, or even being fined,
for failing to provide data to Census takers. Everyone knows that there are
people and businesses which refuse to cooperate; the practice of
non-compliance is already tolerated. But compliance is the law, and this
sets a tone of legality which allows the ACS and other projects to gather
the necessary data.
5. If the data business becomes mostly private in nature, the cost of
obtaining data will largely limit its availability to large corporations
that could afford to purchase it, creating another disadvantage to small
businesses and business start-ups.
6. Here in Little Rock we host one of the country's largest
data-gathering agencies, the Acxiom Corporation. It's an open secret that
Acxiom, and other companies like it, hold vast amounts of data about just
about everybody. While Census data is protected by confidentiality laws,
disturbingly intimate corporate data can be sold to the highest bidder.
7. While the anti-census anti-government lobby argues unconvincingly
about government as "Big Brother," there is therefore another, less
accountable version of "Big Brother," existing in secret corporate
data-gathering. Such data could become the only basis for information about
our society. Without Federal laws, and Executive and Congressional
oversight, who could prevent this private data from being falsified? Without
the credibility of ACS and related programs as a "cross-check," false
information could be fed into the system, and could be manipulated by
private power brokers.
8. Here in Little Rock we have a small spinoff company which has used
Acxiom data to attempt census-like products. Around 2009, they privately
gave me a total for the state's largest county (Pulaski) that disagreed with
my careful estimates. They ended up being high by about 7 percent, compared
with the Census 2010 count that appeared a few months later. My own
estimate, based on housing records, was within 1 or 2 percent. A corporate
representative thought their figures were inarguably correct; I thought
their methods for counting people were flawed. Guess who was right.
9. Data-gathering by the Census Bureau and related agencies isn't
perfect, but it has oversight through the democratic process. I'll trust a
process that's been around since 1790 before I trust a private company that
answers first to shareholders.
It is my earnest hope that the effort to kill the ACS is so blatantly
foolish that it will never make it to a vote by the U.S. Congress or Senate.
I ask those who keep their ear to Congress to please keep the data community
well-informed about this disturbing development.
