US Census

My Third Census

I filled out my Census form today. This will be the third time I’ve had the chance to participate. The first time I was in college, I got the “long form” and was delighted (since not every one got the long form). Which may explain why 20 years later I have a web site dedicated to data visualization of government data.

Here are a couple of examples of visualizations based on data collected by the Census Bureau
U.S. Ancestry
How Much Do You Earn?

US Ancestry: 2000

“The Census Bureau defines ancestry as a person’s ethnic origin, heritage, descent, or roots, which may reflect their place of birth, place of birth of parents or ancestors, and ethnic identities that have evolved within the United States.” from a Census brief on US ancestry. The map below displays the ancestry with the largest population in each county. However, they may not be a majority (>50%) of the population.

Below is the question that was presented on the long form of the US Census. “In 2000, 58 percent of the population specified only one ancestry, 22 percent provided two ancestries, and 1 percent reported an unclassifiable ancestry such a mixture or adopted. Another 19 percent did not report any ancestry at all.”

US Population Density 1990 and 2000

by Catherine on September 7, 2008

I found two maps which show population density in the United States. The relative height of each major city reflects its population. The first map show the population in 1990. It was created by ThoughtForm (formerly Agnew Moyer Smith Inc.) for the book UnderstandingUSA.

The second map show the population in 2000. It was created by Joe Lertola for Time Magazine.

Found the top graph via Paul Krugman’s blog. It is from a paper by Larry Bartels, professor of politics and public affairs at Princeton University.

I found a second graph in the same paper, showing the income inequality year to year (the 80/20 ratio measures the income inequality by dividing the income earned by someone at the 80th percentile by someone at the 20th percentile). Additionally, Bartels has highlighted the years Democrats and Republicans held the White House. Like a number of graphs on my site, you can see the increase in income inequality since the early 70s.

Data in the graphs are calculated from the Historical Income Inequality Tables compiled by the U.S. Census Bureau.

Addendum

5/2/08 Fix my definition of 80/20 income ratio
