At least 1 in 10 U.S. adults carries a concealed handgun!

I’m generalizing a bit from this paper, which reports that 8% of U.S adults now have a concealed carry permit. The true number carrying concealed is much higher, as this astonishing graphic shows: Constitutional carry means a state resident can carry a concealed handgun by right, without applying for a permit; in right to carry states you need a permit that the authorities must issue unless...

Defensive gun uses are very common, but data issues keep them hidden

Basically, the media rarely reports on them, the main federal survey screens out too many by only asking for people who were victims of a crime, and the data archive used by reporters only includes events reported in the media: Americans who look only at the daily headlines would be surprised to learn that, according to academic estimates, defensive gun uses — including instances when guns are...

The political affiliation of college faculty

This guy actually tracked down the party registrations of almost 9,000 faculty members! Interestingly, he finds almost a quarter of faculty at liberal arts colleges aren’t registered to vote. If you assume these individuals are relatively apolitical, then the numbers would look quite a bit different. These are ratios of registered Democrats to Republicans: According to this graph, if you...

The “chart of the century”?

A thought-provoking chart, but I’m not sure this is the single-best chart of the century so far: Various observations that have been made about the huge divergence in price patterns over the last several decades include: a. The greater (lower) the degree of government involvement in the provision of a good or service the greater (lower) the price increases (decreases) over time, e.g...

More data on human feces in SF

A foul odor permeated from a massive bag of human excrement sludge left on a street corner in San Francisco’s Tenderloin district Saturday. The horrendous smell and sight quickly gained notoriety when a Reddit user posted a screen shot of a report made to San Francisco’s Citizen app for identifying crimes. “Twenty pounds of feces dumped onto sidewalk,” the report called...

Data on human feces in San Francisco

Block-by-block surveillance reveals the deterioration of downtown San Francisco. Of 153 city blocks surveyed, 41 contained used drug needles and 96 had human feces present.
Yikes! That’s about 2/3 of city blocks with human feces.

More data on how school shootings rarely occur

From the researcher at Northeastern who wrote the USA Today op-ed; there are some nice graphics. Mass school shootings are incredibly rare events. In research publishing later this year, Fox and doctoral student Emma Fridel found that on average, mass murders occur between 20 and 30 times per year, and about one of those incidents on average takes place at a school. […] Their research also...

Data on school shootings; they are actually quite rare

School shootings in the sense of multiple fatalities, which occur about once a year. From a criminology professor: Everytown for Gun Safety reported that there have been 290 school shootings since the catastrophic massacre in Newtown, Conn., more than five years ago. However, very few of these were anything akin to Sandy Hook or Parkland. Sure, they all involved a school of some type (including...

Data on what Uber drivers make

How are Uber fares calculated? When someone takes a ride with you, they are charged a fare plus a “Rider Fee”. The fare for UberX in Los Angeles is currently $0.18 a minute + $1 a mile. If there is “Surge Pricing” then the entire fare is multiplied by that number. Surge Pricing means Uber increases the fare prices during certain times of higher demand, making these hours more attractive for...
