The data is normalized by number of tweets for a particular region (county, I believe). So what you're looking at is a comparison between the portion of total tweets for a region which is racist/homophobic/disabled-biased. Put differently: If county A has 100 tweets over the time period and 1 of them are racist it will appear identical to county B which has 1000 tweets of which 10 are racist over the same time period.
