MURDER, POLITICS, AND THE END OF THE JAZZ AGE
by Michael Wolraich
The John Hopkins database is attempting to connect information on the most local levels with larger trends.
The link goes the the U.S. but it is a component of a world map.
Testing still in a rudimentary stage on the level of understanding what is happening. Information from local communities is subject to other kinds of limitations. What makes the John Hopkins approach valuable is that they made the model on the basis of what should be understood rather than trying to make one in the absence of information.
