I always enjoy the combination of two of my interests: data visualisation and genealogy. So this BBC article that references a Nature article piqued my interest. It looks at the distribution of DNA across the United Kingdom and identifies different cluster areas. The most important finding is that the Celts, i.e. the people of Scotland, Northern Ireland, Wales, and Cornwall are not a single genetic group. Another finding of interest to me is that the people of Devon are distinct from both Cornwall and Dorset, Devon’s bordering regions. That interest is because my New England ancestors largely hailed from Devon and Dorset.
The colours don’t imply relationships, for what it’s worth

I am unabashedly Irish-American. So, Happy St. Patrick’s Day. But, I am not the only Irish-American in America. In 2013, Trulia put together a post about the Irish in America using US Census Bureau’s American Community Survey data. The post also links to an interactive map looking at US counties by their self-reporting Irish-ness. Not surprisingly, the Northeast is the most Irish, Philadelphia is the 8th largest metro area at 14.2%.
This past weekend Al-Shabab, the Al Qaeda affiliate based in Somalia, threatened shopping malls in the United States, Canada, and the United Kingdom. This threat carries a certain amount of weight given the deadly attack Al-Shabab launched against the Westgate Shopping Mall in Nairobi, Kenya a few years ago.
So what to look at today? Well, a few weeks back a colleague sent me a link to a Bloomberg article about the American shopping mall. The article examines the makeup of stores, the people shopping, and the regionalisation in the food court(s). On a personal note, I was glad to see that King of Prussia received a mention.

People, science is your friend. Vaccinations are not only for the benefit of yourself, but for others. Anyway, let us take a look at the measles outbreak through some graphics produced by the New York Times. It started in Disneyland. Because we had eliminated the disease about 15 years ago. Science, people.
Where the outbreak had spread as of 6 February

Ukraine continues to suffer the effects of a Russian invasion. Though we won’t call it that. This piece from Radio Free Europe looks at the displaced persons in the country. Unfortunately, it is not quite the best example of what to do.
Displacement in Ukraine
The line chart looks at the cumulative number of displaced persons. But, a monthly growth or absolute number for that month would tell a different story. See below. Hint, it slowed down, and then got pretty bad again.
Monthly population change
I am also not a fan of labelling every data point on the map. Maybe call out a few interesting ones, the outliers perhaps. But do we need to know to the person how many people are in Ternopil. Probably not.

Today’s selection is a little old—dating from July of last year—but is still a nice example of an inline graphic supporting the premise of its accompanying article. The New York Times looks at what was then data published by the United Nations on urban growth out to 2030. The article talks about the growth of megacities in lower income countries and those in the tropical regions. So smack in the middle of the article are two stacked bar charts breaking down urban populations into those two categories.
Urban population makeup
Personally I would have preferred a series of line charts to better compare the growth—the lack of a common baseline makes it very difficult to compare segments of the bars. But below the stacked bar charts we have a nice table. Those are always good to see. They organise information clearly and make it quick to find what is relevant.

Last week’s terror attacks in Paris highlight the tension in Europe between secular Europe and those believing in Islamist values. The Economist looked at some of the available data and noted the gap between Europe’s perception of Islam and its reality. A quick figure called out for France, French respondents thought 31% of the French population to be Muslim. The reality is a mere 8%.
Perception vs reality

This is an old map that saw the light of day a while back. Featured on Vox, the map supports the notion that some white people are whiter than other white people. The map explores immigrant populations. Using a map for spatial arrangement of integrated components, the data looks at immigrants’ ethnic origins, their workforce breakdown, and their recent growth.
A look at PA, my ancestors are in that data set
