    Following on last week’s posts on immigration comes today’s post on how that might impact Republican politics. Well I say might but pretty much mean definitely. The graphic comes from the Wall Street Journal and it takes a look at the demographic makeup of states, House congressional districts and then survey data on immigration broken into Republicans…

    Keeping with maps, they can be useful, but all too often people fall back upon them because it is a quick and easy way of displaying data for geographic entities. This graphic from the New York Times on ADHD is not terribly complex, but it uses a map effectively. The article discusses how ADHD rates…

    Today’s map comes from the Texas Tribune out of Austin, Texas. The map displays the location of disposal wells, i.e. the sites where the waste water from fracking and related drilling operations are dumped.

    Detroit’s population has fallen drastically while its economy has been all but eviscerated with the near-collapse of the American automotive industry. But it was not always that way. The National Post looks at Detroit over the years, starting in 1950. It’s the mapping and charting out of the decline and fall of what was once a…

    On Friday Hillary Clinton steps down as Secretary of State to (likely) be replaced by John Kerry whose confirmation votes will (likely) be later this week. One of the big roles for the Secretary of State is to travel abroad and represent the United States. If secretaries go where the US needs to be represented,…

    The New York Times looks at who controlled the redistricting of US congressional seats because of the 2010 census. It then showed an example in North Carolina where Republican control led to the state being less competitive in the past for Democrats. In 2010, Democrats held 7/13 seats in North Carolina. But after the redistricting,…

    Earlier this week, the Office of National Statistics in the United Kingdom released census results for England and Wales. (Northern Ireland and Scotland are reported separately.) England has more people than expected, most likely because of undercounting of immigrants, and Wales is now some three million and counting. There are fewer Christians than expected—and fewer…

The representation of the absentee ballot from Minnesota in 2008 is then examined to see which areas were the reasons for discounted ballots. Follow the directions to the best of…
