Conversely, if the population can be evenly divided among two or more race or ethnic groups, the area’s Diversity Index increases to 100. The Diversity Index measures only the degree of diversity in an area, not its racial composition. Esri’s Diversity Index for the US has risen from 60.6 in 2010 to 61.4 in 2012, with a forecast to increase to 63.8 within five years. Continue reading

Big Data is often described using the Three “V”s: Velocity, Volume, and Variety. By example, let’s take a few of the real world case studies gathered by IBM and provided by Mike Rhodin, Senior Vice President at IBM Software Solutions:
