St. Louis County 	$4,397,769 	$341,291,336 	1.3 	998,954<p>This totals up to around $35MM in Fines and Forfeitures in St. Louis (chosen due to Ferguson and all the articles around Mike Brown). Anyway WAG numbers this looks to be about 80% of the neighborhoods on the highways but it&#x27;s got the 2 major players (city &amp; county) so lets call it good.<p>St. Louis is 21st (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_metropolitan_areas_of_the_United_States" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_metropolitan_areas_of_...</a>) in Metro area size, so that gives us $755MM if everything was actually the size of St. Louis.<p>However if I just add all the pops from 21 up I get 146MM people, so that means that if scaled linearly for St. Louis (which may or may not be right), we&#x27;re talking $1.763MM, so around 1.75BN for the 21 biggest cities in the US.<p>Easy to say that traffic stops in the US are well over a billion.<p>Way over analysis but it shows scale of traffic income. If you read the first article linked, it points out the share of revenue this. It can be up to 36% of revenue for small municipalities.
