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 provin... Read more →

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 nati... Read more →

Nate Silver chimes in by allu... Read more →

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 GO... Read more →

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: Read more →

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 progre... Read more →
