March 27, 2015

In Which Part of Beijing Are There The Most College Graduates?

March 20, 2015

While the districts of Xicheng and Dongcheng represent the core of Beijing and have real estate prices on par with many of the most expensive cities in the world, the part of Beijing with the greatest percentage of people with a college degree is in Southeastern Haidian District, where most of the top-tiered universities, like Tsinghua University, Peking University and Renmin University of China, are located. Certain sub-districts in Chaoyang, where most Fortune 500 companies and expatriates live, also have a higher percentage of college-educated population compared with other areas.

Which Neighborhood In San Francisco Has the Highest Average Income?

March 3, 2015

What neighborhood has the highest average income in the City of San Francisco? Surprisingly, it’s not the well-known neighborhoods in the Northern part of San Francisco like Pacific Heights, Presidio Heights, Cow Hollow or the Marina. It’s actually West Twin Peaks and Noe Valley, both in the Southern part of the city. We would surmise this has something to do with the explosion of wealth in Silicon Valley and the desire of dot-commers to live in San Francisco. Worth noting is Portrero Hill and Bernal Heights, also in the Southern part of the city and also with significant average income.

Of course, if you go North to Marin or South to San Mateo County, you will find neighborhoods with substantially higher average incomes.

On Pie Charts and Their Utility

March 29, 2013

 

Edward Tufte has long claimed that pie charts are entirely useless. The polemic linked in these images and below argues that there are cases where not only are pie charts useful, but they are clearer than bars or other types of charts. Consider the images above: when comparing individual segments, the bar chart is clearly superior and makes comparisons elegant and simple. However, if the intended point is to show that companies B and C control the majority of the market, then a pie chart is enormously effective. Click through for a well reasoned championing of pie charts.

Why Tufte is Flat-Out Wrong about Pie Charts
