News Maps: Unauthorized Immigrants and Gulf Oil Spill
Two prominent uses of maps as visual aids in news stories late this week - first up, the Washington Post's state-by-state map of "unauthorized immigrants as a percentage of state population." Based on 2008 data, the map also includes a chart showing the estimated increase of this percentage in Arizona over the past 20 years.
Meanwhile, the New York Times released this time-lapse animated map showing the growth and movement of the Gulf of Mexico oil slick. While this isn't the most impressive NYT map ever, it does dramatically show the steady crawl of the slick toward the vulnerable coastline.
