Deep into the Immigration Situation in U.S. is the final project of Information Visualization, the course offered by Dr. Yu-ru Lin in Fall 2014 at iSchool, University of Pittsburgh. I learned a lot from this course and got a good grade. Our team’s final project has been elected as the best overall visualization among all projects in our class. Welcome to visit the list of projects of the course here (I’m in Group 10).
There are 3 part in this immigration data visualization system: (a) historical trend between 1820s and 2000s; (b) immigration flow from continents to states in 2012; and (c) factors analysis by regions in 2012. I’m going to introduce the third part of the system in this post.
PART 3 Factors Analysis
I chose bipartite graph to visualize the factors of immigration situation by regions in 2012. The left sets represent regions; the right sets represent factors. There are 5 categories of factors: gender, age, marital status, occupation, and broad class. User also can select “where are the immigrants from” regions or “where are the immigrants go” regions.
When users hover on certain factor or region, the detail percentage will display.
Using this visualization, users could observe some interesting information. For example, do you know there are more female immigrants came to U.S. in 2012? In the following image, we could see that there are 55% female and 45% male that came to U.S. in 2012. We also could know that one-third immigrants like to live in south region but only 12% of them like to settle down in midwest.
Another example is occupation distribution. The following two images tell us that more Asian immigrants came to U.S. and worked in management related field (57%) than worked in production related field (29%). However, more immigrants from other countries in North America worked in production related positions (52%) than worked in management positions (13%).
More fun will be observed when you play with it.
Part 2 Immigration flow
I also chose bipartite graph to visualize the immigration flows in 2012. It is a great representation for flows. The left sets represent where-are-they-from; the right sets represent where-are-they-going-to. Therefore, the left sets are continents in the world and the right sets are states in U.S. The map will display the top 10 hot states that immigrants love to settle down of a certain immigrant group. You can see that plenty of immigrants are from Asia and North America, and the top 4 states which immigrants love are California, Florida, New York, and Texas.
I designed this visualization but I didn’t code on it. My team partner Jin was working on it. Please feel free to play with this visualization here.
This whole project contains an online visualization system, a demo, and a paper. Welcome to download the final paper and demo to explore more details. Also feel free to play with this visualization here.
