More Election Cartography Primers

Today, print subscribers to the New York Times were treated to a fold-out map showing a choropleth map of the 2012 election results at the ZIP code level (above). “The map is part of a special election section that aims to help explain the political geography of the United States — identifying where people who are conservative and liberal live and pointing out how physical boundaries, like the Rio Grande and the Cascade Mountains, often align with political ones,” writes the Times’s Alicia Parlapiano.

Parlapiano’s piece is in fact a lengthy tutorial on how to read election maps, along the lines of the pages I linked to in last week’s post on election map cartography—it outlines the problems of state-level election maps and choropleth maps that privilege area over population, for example, and shows some other ways of depicting the results.

It can’t be a coincidence that in today’s Washington Post we have Lazaro Gamio’s article dramatically highlighting the difference between area and population size with comparative maps. Mark Newman’s cartograms also make an appearance.

I can only conclude that both the Times and the Post are making efforts to educate their readers before the election results start coming in, one week from tonight. (Deep breath.)

Mapping Obamacare

The New York Times maps the decline in the numbers of the uninsured since the implementation of the Affordable Care Act.

Over all, the gains are substantial: a seven-percentage-point drop in the uninsured rate for adults. But there remain troublesome regional patterns. Many people in the South and the Southwest still don’t have a reliable way to pay for health care, according to the new, detailed numbers from a pair of groups closely tracking enrollment efforts. Those patterns aren’t an accident. As our maps show, many of the places with high uninsured rates had poor coverage before the Affordable Care Act passed. They tend to be states with widespread poverty and limited social safety nets. Look at Mississippi and Texas, for example.

Mapping Same-Sex Marriage in America

The number of same-sex marriages in the United States is not directly tracked. But a new Treasury Department research paper has been able to come up with a count of same-sex marriages by looking at jointly filed tax returns; the New York Times story is accompanied by a nice interactive map of such marriages by zip code.

The Geography of American Incarceration

The New York Times maps “the geography of American incarceration,” in an investigative piece that includes an interactive map showing prison admissions per county. They’ve diverged sharply in recent years: less populous, more rural, more conservative counties are doubling down on being tough on crime.

Just a decade ago, people in rural, suburban and urban areas were all about equally likely to go to prison. But now people in small counties are about 50 percent more likely to go to prison than people in populous counties.

They’re also more likely to get much stiffer sentences—something the map is not able to track.

The Cartography Behind Super Tuesday

Further to my last post, here’sNew York Times article on the technology behind their Super Tuesday election map.

There was a time, not too long ago, when our Super Tuesday map would have been impossible to put together and display. Even earlier in the digital era, a complete vote-totals map wouldn’t have been available until every ballot was counted at the end of the night. (Not to mention that in the print-only era, no map would be available until two days after the vote, and then often only in black and white.)

The New York Times Maps the U.S. Presidential Primaries

The New York Times graphics department invariably does first-rate work, and their interactive maps of the U.S. presidential primary and caucus results are no exception. You can zoom in, you can get results by county or congressional district (depending on the state), you can choose to view margin of victory (see screencaps below) or each candidate’s vote share.

The Democratic candidates as of March 9:

Mapping U.S. Drug Overdoses

The New York Times maps the rise in deaths from drug overdoses. “Some of the largest concentrations of overdose deaths were in Appalachia and the Southwest, according to new county-level estimates released by the Centers for Disease Control and Prevention. […] The death rate from drug overdoses is climbing at a much faster pace than other causes of death, jumping to an average of 15 per 100,000 in 2014 from nine per 100,000 in 2003.” [via]
