UPDATE – 8/2/16: CIRCLE changed its method of calculating votes cast using the Catalist voter file to use a different variable for determining age. As a result, our voting data for congressional districts is no longer the best available. Until we are able to update the votes cast data to a reliable estimate, we have disabled the votes cast tab that was on our interactive map.
In May, as part of our lead-up to this year’s midterm elections, we released a state-by-state map of youth voter turnout, voter registration, and youth demographics. Today we present another tool for those interested in exploring the role of young people in American politics: an interactive map of youth voting and demographics by congressional district.
The map features votes cast and population data on young people (ages 18-29) and older adults in each congressional district. The voting data includes statistics from the latest midterm (2010) and presidential (2012) elections. The map also displays district-level data on several economic, social, and demographic indicators, as well as a snapshot of which 2014 congressional races currently rank as competitive and select ballot measures in several states.
About the Map/How to Use:
- Most of the data is from the Census American Community Survey’s 5-year estimates (2008-2012). The bottom of that upper-left panel explains the source of the data for each category. The sources for data that continue to change (e.g. ballot measures; race competitiveness) have are indicated as well.
- The tabs at the top of the map shift the view to each of the data categories (Economic, Demographic, Social, etc.). Within each category, you select specific indicators from the drop-down menu under these main tabs, or from the toolbar on the upper left-hand corner.
- A map legend (lower left-hand corner) indicates the range of color gradations for each indicator. For “Votes Cast,” the time scale at the bottom of the map will allow you to choose between the 2010 and 2012 elections.
- In addition to the interactive map, you can view the data in column, bar, and line graph formats, as well as bubble charts and scatter plots. You can switch to these views by clicking on the corresponding icons on the upper left hand portion of the center window.
The interactive map also allows you to create comparisons between districts by selecting them in the regions box (upper right-hand corner). On the lower left-hand corner of the map screen area, different icons allow you to modify the view of the map itself: making it full screen, showing and hiding certain features, adding proportional symbols, or bringing up a table with one or more indicators. You can also export the data, graphs, or the map itself. (Please note that certain browsers may prevent data export.)
The last icon allows you to create a unique link to the specific indicators you are looking at. It’s a great way to share what you’re looking at on social media!
