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.
Cleanup and aggregation:
At the Creating the Policy and Legal Framework for a Location-enabled Society conference in Boston, Kirk Goldsberry, who is a Visiting Scholar at the Center for Geographic Analysis at Harvard, gave a fascinatng presentation with the help of two of his students on the topic of personal geographic data and privacy. Geoff Zeiss provides a recap.
