W.E.B. DuBois and the Hand-Drawn Infographic

[Link to W.E.B. DuBois infographics at the Library of Congress]
In preparation for an exhibition at the Paris World’s Fair, W.E.B. DuBois commissioned hand-drawn infographics that illuminated how black Americans lived in the 1900s – mostly illustrating the great progress of this population since the end of slavery. In addition to the overview of the life of blacks in the United States, there was a special focus on “The Georgia Negro.” At the time, Georgia had the largest black population among all the states. These infographics were drawn by his students at Atlanta University – now Clark Atlanta University. He wanted his students to combat racism with empirical data.

Muzzling Federal Scientists

Breaking news: scientists in selected federal agencies have been told to no longer update their websites with reports, factsheets, etc. Here’s a summary of the memo that the Environmental Protection Agency got:

The memo said there would be no press releases, social media posts or blog messages until further notice. It also asked for a list of external speaking engagements for staff and any planned webinars. It warned that listservs would be reviewed and that staff should “only send out critical messages, as messages can be shared broadly and end up in the press.”

Note, that this happened under the Harper government in Canada [summary]. And Canadian scientists warned US scientists of this possibility a month ago:

Federal Policy for Protection of Human Subjects

A final update to the regulations that govern Human Subjects research that have been in place since 1991 was released today. The original notice to update/change the Common Rule was proposed in Fall 2015 with an opportunity for reactions to it. And, plenty of folks made comments about some of the proposed revisions and at least some of these were dropped. The Science article below briefly discusses the controversial consent proposal, while the Bill of Health Blog gives a quick overview of what stays the same and what has changed. The Bill of Health blog also discusses some implementation issues, e.g., could the 115th Congress reject this, etc.

Health ABC data available through NIA website

NIA’s Health, Aging and Body Composition (Health ABC) Study is now available on NIA’s website for qualified researchers.

The Health, Aging and Body Composition (Health ABC) Study began in 1997 and collected data for 17 years on a cohort of older black and white adults living in Memphis and Pittsburgh. Participants were aged 70-79 at baseline…

…[It] is an interdisciplinary study focused on risk factors for functional decline in healthy older people. With a particular focus on change in body composition with age, the study was designed to address differences in onset of functional limitation, disability, and longevity between older men and women, as well as between blacks and whites.

More apportionment fun

The Census Bureau just released its 2016 Population Estimates. Let’s take a peek at what the Electoral College might look like in 2020 using the PSC Apportionment calculator. The easiest calculation is to just put the 2016 estimates into the calculator (remember to delete Washington, DC). In that scenario:

The losers: Illinois, Michigan, Minnesota and Pennsylvania
The winners: Florida, North Carolina, Oregon, and Texas

If we take the 2010 to 2016 growth rate and extend it to 2020, this is the scenario:

Losers: Alabama, Illinois, Michigan, Minnesota, New York, Ohio, Pennsylvania, Rhode Island, West Virginia
Winners: Arizona, Colorado, Florida (2), North Carolina, Oregon, Texas (3)

Notable in this scenario is Rhode Island losing an electoral seat. It is just slightly larger than Montana – 1,056,426 vs 1,042,520. But, Rhode Island has had an extra seat since 1990 when Montana lost 1 seat in the House of Representatives. Montana is on the cusp of getting that 2nd representative in the House – it just needs ~5,000 more people than our 2020 projection, which is not an unrealistic scenario.

One thing that is unrealistic about the previous scenario is the fast growth of North Dakota during this period. North Dakota has been the fastest growing state for the past 4 years, but its growth rate dropped to 37th fastest in 2016 due to the collapse of oil prices and thus the fracking industry. Thus, a more realistic estimate might be to use the 2015-2016 rate for the last 4 years of the decade. In that scenario, the results are exactly the same, except that now Montana needs only 550 more people to gain a 2nd seat in the House of Representatives.

Mapping Megaregions via ACS commuting data

Two researchers have created a map of megaregions in the US based on commuting data from the American Community Survey (ACS). The results are covered in both the popular press and in PLOS One. The latter provides more details about how they constructed the maps – it wasn’t just via a mapping program.

Risk Visualization Theater

How to better communicate election forecasts — in one simple chart
Justin Gross | Monkey Cage blog [Washington Post]
November 29, 2016

Most folks were surprised by the results of the 2016 Presidential election and this was in part due to some of the rosy forecasts by some of the poll aggregators, like Huffington Post. But, even when a site had a forecast with a 30% chance of Trump winning, most people have trouble understanding that a Trump victory was possible. The explanation:

But certain representations of probability are more readily grasped than others. In particular, we have trouble understanding risk in terms of the “percent chance” but we do better when simple raw numbers of different outcomes are depicted visually.

Solution: Show the risk as a “Risk Visualization Theater.” Below are the representations of forecasts of victory for Trump via FiveThirtyEight, NYT Upshot, and Huffington Post Pollster. The filled theater seats (in black) represent the chance of a Trump victory. Clearly, the chance of that event happening don’t look so remote in the far left depiction, but look very unlikely as one moves to the right.

Missing girls in China maybe weren’t missing after all

China has had a highly unbalanced sex ratio at birth for years leading to an estimate of 30 to 60 million missing girls. The traditional explanation was male preference, exacerbated by the one-child policy, which led to sex selective abortion and/or infanticide. New research presents evidence that maybe the missing girls were never missing after all.

Detroitography Mapping Seminar

blog header

A 2-hour workshop on mapping data from Detroit is offered on Thursday, November 3rd on campus. Perhaps as useful is meeting the presenter who is the founder of Detroitography.com a group that is all about maps and geography of Detroit. And, that also means geographically-referenced data.
