Description

Using historical apportionment data over the past 100 years, available in table form here: http://2010.census.gov/2010census/data/apportionment-data-text.php
we illustrated the relative per-person representation in U.S. Congress as a thematic map and series of state-based sparklines.  The map is shaded by the ordered rank of personal representation and the sparklines show congressional seats gained and lost over the past 10 decades and the impact that it, in conjunction with population change, had on a person’s proportional representation in Congress compared to the national average.  Whew.
