| 説明 | Population density and Twitter geotag density seem to be very close to being linearly related, except that the very most densely populated areas have a slightly higher rate of geotagging, and the very most sparsely populated a slightly lower rate, and that there are some places with no population at all that do get geotagged (perhaps parks, monuments, and large shopping or office areas).Top: Scatterplot of population and geotags for all half-mile squares of the US (log-log scale), and linear fit to the points.Bottom: Accumulation of geotags from the most densely populated to the least densely populated half-mile square.US Census 2010 populations and counts of tweets from the Twitter streaming API for half-mile squares (one quarter square mile) of the United States. |
