Mapping Opposition to the GOP Health Care Bill by Congressional District

The legislative failure of the GOP’s replacement for Obamacare has been widely reported, obviously, but I remain interested in one bit of polling noted this week by FiveThirtyEight. The polling firm YouGov estimated the legislation’s unpopularity by congressional district. The bill itself was quite unpopular, it turns out, even in conservative districts, as FiveThirtyEight’s Nate Silver reported. Thanks to DailyKos Elections, we can also marry the data with President Donald...

Mapping South Korea’s Total and Foreign Populations — by Municipal District

South Korea, my adopted home for almost two years, has about 50 million residents as of the last census, in 2015. Most of them are settled in the country’s urban areas. About 22 million residents, for example, live in Seoul, the capital in the country’s northwest corner, and its adjacent province, Gyeonggi. As an experiment to create a choropleth map with D3 and NPR’s dailygraphics rig, which drives most of...

Four Decades of State Unemployment Rates, in Small Multiples, Part 2

I posted recently about how the state-by-state unemployment rate has changed during my lifetime. The result was a small multiples grid that put the states in context with one another. Today I’ve created a new version aimed at identifying more precisely how each state has differed from the national unemployment rate during the last four decades. The lines show the percentage point difference — above (worst) or below (better) — from...

Four Decades of State Unemployment Rates, in Small Multiples

There’s good news this week in the monthly jobs report, the latest sign that the economy, however grudgingly, has healed from the financial crisis nine years ago: The unemployment rate fell to 4.6 percent, the Labor Department said, from 4.9 percent. The last time it was this low was August 2007. That was the month, you may recall, when global money markets first froze up because of losses on United...

Charting Historical Voter Turnout

As FiveThirtyEight notes, turnout in the 2016 presidential election isn’t dramatically lower than it was four years ago, according to the latest estimates. And with many mail-in and provision ballots still being counted, the 2016 turnout rate could still change: Approximately 58.1 percent of eligible voters cast ballots in last week’s presidential election, according to the latest estimates from Michael McDonald, associate professor at the University of Florida, who gathers...

Mapping Where ‘Americans’ Live

Back during the Republican primaries, The Upshot published an interesting short post called the Geography of Trumpism. The reporters back then analyzed hundreds of demographic variables, by county, in an effort to determine which ones might be predictive of electoral support for the eventual GOP nominee. Think: What’s the rate of mobile home ownership? Or what percentage of people in a particular place have college degrees? They found a key...

Charting MLB Division Races

Earlier I used small multiples to show how each Major League Baseball team’s 2016 season progressed relative to the .500 line. Here are those same line charts, but this time I’ve grouped them by division:

How Far Above (Or Below) .500 Did Each MLB Team Finish This Season?

I live in South Korea, where it isn’t always easy to watch American baseball (unless you’re a fan of the Los Angeles Dodgers or the Texas Rangers). So I’m catching up with data. These charts show teams’ performance by tracking how many games above (or below) .500 they moved as the season progressed. The Chicago Cubs did best (45 games over), while the Minnesota Twins did the worst (-44 games)....

Charting American Birthdays: Yours Probably Isn’t That Special

Last week I published a new heatmap exploring the popularity of American birthdays. The chart, which uses darker shades to represent higher average birth counts on specific days, can give the impression that some birthdays are much more common than others. In reality, outside of some special occasions, namely major holidays, there isn’t a huge amount of diversity in the data set, which has two decades of births aggregated by...
