The following graphic is a bubble chart showing the population of each county in the United States as of the 2014 5-year American Community Survey. Below this first map of the total population are nine additional race breakouts. Note that because the ACS is a survey, not a census, there are margins of error associated with each value. Larger populations can be estimates with a greater degree of certainty than small populations. The Census Bureau attempts to over-sample minority populations to obtain more accurate values, but margins or error do exist.
All of the maps are can be zoomed in using your mouse wheel and panned with your mouse. The cursor needs to be over the graphic to zoom the SVG element. Alternatively the entire browser can be zoomed as well. If you cannot zoom all the way back out to see the whole graphic, simply refresh your page! These maps will print exactly as they appear onscreen as well. If you're interested in something like this for a presentation or other geographies, contact us, we'd be happy to help you. We also have the ability to map much more than just population. Quantity of persons without a high school diploma or people whom where unemployed in the last 12 months are other possibilities. This page will be added to in time, check back with us!
