U.S. News in 2019 After the US university rankings were updated, I believe that the first impression of many people is that this year's ranking is a bit bigger than last year's change. For example, the public school of the University of California, Santa Barbara, ranked 7th in the list of 30, and Clark University increased from 81 to 66, a total of 15 progress; UC Riverside has improved 39 There are so many, from 124 to 85. It can be said that the ranking in 2019 is the biggest change in U.S. News in recent years. Based on the principle of using data to speak, we have made a statistic for the ranking data of the previous 10 years, and listed the average value of each year as shown below (only the top 150 schools are counted here, because the ranking data of these schools are compared. complete):


The calculation method uses the simplest average value of the absolute value of all school ranking changes. From the figure, we can clearly see that the ranking change in 2019 is much larger than the previous years, equivalent to an average of each. Compared with the previous year, the school has changed its ranking by nearly 6 places, while the previous years mostly lingered around 2.5. Seeing here, I believe that every reader has the same doubts as the author. Why is the ranking change so great this year? With this doubt, the author reviewed the calculation method of U.S. News ranking this year. The original reason is that U.S. News changed the ranking algorithm [1] this year. The biggest change is to join the social class mobility, which affects 5%. Then the author will come to talk about the mobility of this social class.


First, let's take a look at Wikipedia's definition of the prevalence of social class: the variability of individuals, families, or other groups in the social class can be divided into upward flow or downward flow, and needs to be defined by a numerical value (usually we Will be defined by the value of wealth) [2]. In fact, when I discussed the value of American famous schools not long ago, I also discussed the issue of the mobility of American social class [3]. The calculation method adopted at that time was to enter the university before the social wealth of the family. At the bottom of the 20% of the students entered the top 20 after graduating from university. The ratio of % is basically consistent with the definition of Wikipedia. Then let's take a look at the way US News calculates the social class liquidity scores: the first is the 6-year graduation rate for students who have received Pell Grant in the US, and the second is the 6-year graduation rate for students who have received Pell Grant from the United States. The ratio of the six-year graduation rate of all the students in the school, which accounted for 2.5% of the total scores of all the schools, respectively, here is a simple US Pell Grant equivalent to the US national bursary, generally awarded to the bottom 40% of the university Undergraduate. After reading U.S. News's calculation of the so-called social class liquidity score, the author is actually skeptical.

It can be seen that most of the top American elites are children of the top-level families of the society. The consequences of the top-level resources of these elite schools must be the intensification of social class solidification, so I am very supportive of this change in US News here. After all, this is the first time that the concept of social class mobility has been introduced in the list of American university comprehensive rankings. After all, promoting social class mobility is a responsibility that universities should shoulder, and US News has stepped out of this step to encourage universities to take up this responsibility, although the current scoring standards cause this effect to be indirect and not too Obviously, but I believe that US News will improve this rating in subsequent improvements. Moreover, the author has done some research and found that the American University Pell Grant data is the most complete, most statistical and most time-sensitive public data on the mobility of American social classes. Other data such as The Equality of Opportunity Project [4] is lacking. Timeliness and continuity, CollegeNet's SMI Rankings[5] does not address students' enrollment and graduation data, so the author agrees to use Pell Grant data as the basis for scoring, if you can introduce graduates on this basis. Salary, household income, and other data reflecting the distribution of students' post-graduation levels will make this change in US News more perfect.
