You should have included the data from India! What's (very) surprising is that, using data from '23, it has 12.5 road injuries per 100k people. In other words, it's only slightly higher than the US!

If you've ever driven in India, this statistic should shock you.

According to exit polling, a majority of Jews and Catholics voted against Mamdani. If Mamdani wins with over 50%, this could reshape future mayoral elections in NYC.

According to exit polling, a majority of Jews and Catholics voted against him. If he maintains a winning percentage above 50%, this mayoral race could redefine future mayoral races in NYC.

2/ There however is a solution using a definite integral. This is called the error function. That is, one solution to an integral has its own name and set of theorems:

2/That is, this could motivate the CCP to retaliate against the US by restricting rare earth imports.

In any case, this news story is not getting headlines in the US but it has the potential to greatly influence the trade war between the US and China.

South Africa's apartheid system was designed according to Christian teachings and Christian nationalism -- and Afrikaner nationalism. My point: Christianity has been -- and likely will be -- a force against its core values:

HEARTLESS LOVE: CHRISTIAN NATIONALISM IN APARTHEID SOUTH AFRICA AND TRUMP’S AMERICA — Earth and Altar
Many Americans refer to “Christian nationalism” as a new threat, but the concept has deep and unsavory roots in South African history. (1) In the 20th century, the Afrikaners—white descendants of 17...

Worth considering: tariff revenue is log-linear -- not linear. That is, as tariff revenue increases, Americans will change their behavior to avoid them and therefore they'll decrease. Or, the longer the tariffs are in place, the revenue generated logarithmically decreases.

Worth pointing out: the same poll (AP) was held in June. Then, 70% of Republicans said the country was on the right track. Now, in September, the percentage has dropped to 50%. Yet, his approval rating amongst Republicans (in the same poll) is unchanged.

What's the point of publishing a poll, such as this, which most likely can be statistically classified as an outlier? I mean, I assume that this poll cost many thousands of dollars to do. Why spend the money when 1) the result is predictable 2) all your others polls are also outliers.

Trump may not realize this but his actions may set the precedent for Democrats trying to take Fox News off the air in 2029 -- assuming the obvious.

This is a long-running topic in academic literature. Specifically, why people in the majority overestimate the percentage in the minority. (Btw, this is for all countries, not just Americans.) EG: Americans estimate the number of black Americans at 41%. It's 13%.
