Marriage Rates

Well, so about that whole Michael Flynn furore thing I wrote about yesterday…. Time to add another name to the list of people to be appointed—as I said, that post isn’t confirmed, merely appointed.

But today is Valentine’s Day. So for all you lovebirds out there, here are some graphics showing how rate of marriages has declined in the United States.

It does a real nice job of presenting the overall national view, but then breaking that down into a state-by-state comparison over time, the small multiples shown below.

My critique would be the labelling. Note how the state label appears above the chart, but how when stacked in a row, the label for the state below appears far closer to the chart above. The first few times I looked at this, I saw the label for the chart as being below. And I was therefore curious why Kansas was so different from the rest of the plains state. It just goes to show you how important spacing and layout can be on the page.

Snowfall in Philadelphia

Today, 9 February, it finally snowed significantly here in Philadelphia. In Chicago it probably snowed shortly after I moved out in September. Today’s graphic is a forecast map from philly.com using National Weather Service (NWS) data.

I fail to understand the divergent palette—to be fair this is not the only instance of it throughout the meteorological world. There is a split at the six-inch mark—but why? If anything, my eye would think that the 4–6 range is the heaviest, not the yellow. Snowfall is usually more of a continuous range, and so both within the blues and yellows you get that through a softer edge as the colours become more intense. And then you hit the six-inch mark and a violent shift.

I am also curious as to why the choice to use a coloured map background. Especially if the colour, a lightish green-blue is so close to the lightish blue used by the map to forecast snowfall.

In short, I think this Philadelphia map could use some attention from some designers to make the message a bit clearer.

To Visit or Not to Visit

Well we’re less than a full two weeks into the Trump administration and oh how he has upset people. So much so that after being offered a state visit to the United Kingdom, the people of the UK drafted and are signing a petition to attempt to prevent Trump from visiting the UK.

This map from the Guardian, screenshot below, looks at how the signatures are distributed across the UK.

Old Las Vegas

During my time at the Mob Museum in Las Vegas, I came upon this illustrated map of 1930s Las Vegas and its environs. It shows the audience all of the various entertainments and attractions in the area, from the hubbub of Las Vegas to the natural scenery of the Grand Canyon. The gaming industry had yet to really take hold, as you can see from the lack of the Strip. It’s not a particularly data-heavy map, so it sort of fits for the Friday section of the blog.

Philadelphia’s Growth Since the 1940s

I stumbled upon this article last night on philly.curbed.com that takes a look at the growth and slowdown in said growth in Philadelphia. For the purposes of this blog, that included an animated .gif that showed the expansion in the metro area since the 1940s.

My quibble with the piece is that the lighter blue loses out to the darker. And so one really sees the presence of the city at the expense of the growth. I wonder if reversing the two colours or in some other way de-emphasising the areas built up would allow the new growth areas to come to the forefront of the map.

The United States of Blank

Well, you made it to the Christmas holidays. First, some housekeeping, my posting next week might be a bit sporadic. Not that it hasn’t been sporadic the last few months.

Second, it’s a Friday, so let’s take a look at that federal republic of states we talked about yesterday. According to xkcd, of course.

Capturing a US Navy Drone Submersible

Last Friday China seized a US Navy submersible drone—like the drones the Air Force uses but for underwater purposes—in international waters off the coast of the Philippines. This graphic from the Washington Post shows how, while in international waters, the seizure occurred not far outside China’s Nine-dash Line, which they claim as territorial waters.

The Electoral College

Well today we elect the president of the United States. Wait! you say, did we not just do that a few weeks ago?

Not really, no.

In the run up to the election, I and others saw the possibility that this election could result in a gap between the national popular vote and the electoral college vote. And people think that unfair. Consequently I decided to start working on a series of graphics to help explain the system. But before I could finish, the Washington Post published this piece that I think does a strong job. So, I am going to point you there instead.

The United States is not a democracy, but a federal, democratic republic. Though that may smack of wordsmithery, it is an important distinction. We are a democratic republic in that we elect people to represent us, we do not directly vote on matters of government. And then that federal bit. The United States was formed by sovereign states, i.e. the colonies and other independent republics like Texas and (sort of) California. Others were territories belong to sovereign states that we acquired through negotiation, e.g. the Louisiana territory and Florida. In short, the United States is not a unitary state ruled by an all-powerful central government. The central government only has the authority granted to it by the states and territories entering the union.

States are intended to be equal, but the democratic republic bit means the people need to have their say. So the federal House of Representatives gets a set number of seats divided proportionally by population (as determined by the US Census) while the Senate represents all states equally with senators. The House is elected by the people every two years and thus is more in tune with national public sentiment. The Senate serves as the more deliberative body tempering perhaps overly reactionary House legislation. It also serves to represent the interests of the state governments. Initially, you did not even vote for senators. Those were chosen by your state governments, often the state legislature. (I will save that topic for another day.)

The electoral college of 538 members comes from each state’s House delegation and its two senators. And because this is a federal, i.e. state-led, republic, each state determines how to divvy up their votes. Most states do winner-take-all. Two, Maine and Nebraska, allocate them based on who wins the House districts and then an additional two (from the number of senators) to the overall state winner.

That very complicated system was designed to ensure that states with smaller populations are not summarily outvoted and overruled by the largest of states. This initially helped the smaller states in the Northeast like Maine, Rhode Island, Connecticut, and Delaware, but also the slave states like Georgia. In 2016, this means that the states of the Great Plains and Rocky Mountains receive overrepresentation at the expense of the larger states like California, Texas, New York, and even my Pennsylvania.

The graphics from the Washington Post do a great job of showing not just how states today are over- or under-represented, but how that has changed since 1960. That is an important date given the Voting Rights Act that attempted to break down systemic injustices against minorities, particular blacks, in elections.

This small multiple map of the United States shows representation changes over time. Really well done.

Is the electoral college “fair”? If this was a unitary republic, no. I doubt anyone would or could argue that point. But the United States is not and was not meant to be a unitary republic. We are a collection of sovereign states that grant power to a federal government. So in that sense, the electoral college is a fair, albeit not perfect, system that seeks to reallocate electoral power from high population states to low population states.

Mapping the Country’s Brain Drain

Alternatively known as the zombie food map. Sorry, but I couldn’t resist that one. Today we look at a piece from Bloomberg that maps brain drain across the country. What is brain drain? Basically it is the exodus of people with advanced degrees and education employed in science-y industries and fields. So this map shows us where the brains are moving from and where they are moving to.

Income Inequality

On the lighter side of things we have today’s post on income inequality. Always a lighter subject, no? Thanks to Jonathan Fairman for the link.

Herwig Scherabon designed the Atlas of Gentrification as a project at the Glasgow School of Art and it was picked up by Creative Review. It displays income as height and so creates a new cityscape of skyscrapers for the wealthy and leaves lower income residents looking straight up. His work covered the US cities of New York, Los Angeles, and Chicago. The image below is of Chicago. I probably was living in a cluster of mid-rise buildings despite living in a five-story building.
