While the Census Web site is generally your best bet for population data, you should consider using statistics from the Pew Hispanic Center if you are focusing on the Hispanic population. The Pew Hispanic Center provides a level of analysis that would be difficult for most infographic artists to tease out of datasets from the Census site, especially on deadline.
Some of you are probably curious about how Pew made this three-dimensional data map. I haven’t spoken to the cartographer who made this, so I can’t say for sure. But I have worked on similar maps using either Arcview’s 3D Analyst plugin or with the Bryce 3-D program. With Bryce you extrude a shaded data maps so that the percentage of gray in each county is translated into an elevation figure. Essentially you trick Bryce into thinking your data map is a digital elevation model (DEM), a file that cartographers use to portray mountains and valleys.
