Big Cities Have Fewer Tweeters Per Capita

Walking in New York City is almost a competitive sport. And people in cities really do walk faster than their country counterparts—2.8 feet per second faster, according to a worldwide study in the 1970s. But that speedier pace of life extends to other aspects of city living, too.

在纽约散步几乎是一项竞技运动。在20世纪70年代的一项世界范围内的研究表明，纽约生活的人确实比美国其他城市的人步伐快些——每秒快2.8英尺。但是，更快的生活节奏也延伸到了城市生活的其他方面。

"There's more inventions per capita in large cities, there's more mobile telephony usage in large cities." Lav Varshney, an information theorist at the University of Illinois at Urbana–Champaign.

大城市的人均发明创造更多，大城市的移动电话使用率也更高。”伊利诺伊大学的厄巴纳-香槟分校的信息理论学家Lav Varshney说道。

He says you might expect Twitter use to increase in larger cities, too. But after analyzing² two and a half million tweets, from 50 U.S. cities, his team concluded the opposite is true: There's actually less tweeting per capita as population rises.

他说，你可能预计Twitter使用量在大城市会增加。但是，在分析了50个美国城市的250万条推文之后，得出了相反的结论:随着人口的增长，人均推文量实际上减少了。

But those who do tweet in big cities are more prolific—tweeting more often, on average, than their small-town counterparts. "And so what we discovered is that there's a core of people we call "town tweeters" that seem to emerge. And those people are actually tweeting a lot. And then everyone else is not tweeting very much in large cities. So those "town tweeters" are actually serving as an information broadcast infrastructure³."

但在大城市里发推特的人比他们的小城镇的同龄人发推文的频率多。因此，我们发现有一个核心人物，我们称之为“镇推特人”，似乎出现了。这些人实际上经常发推特，而大城市的其他人并不经常发推文。因此，这些“城市推特人”实际上是信息广播基础设施的。

Their analysis is in the journal SAGE¹ Open.

该研究结果发表在《SAGE open》杂志上。

Of course the faster pace of life in big cities also means that these days, lots of people text and tweet while they're walking. In a 2018 remake of Midnight Cowboy, maybe a more accurate line for Ratso Rizzo would be…, "Hey! I'm tweeting here!"

当然，大城市生活节奏的加快也意味着现在，很多人在走路的时候发短信和推特。在2018年重拍电影《午夜牛郎》,或许更准确为自编台词里是…,“嘿!我在这里发推文!”
