Viewer Choice Presentation

The visualization that I chose for my Viewer Choice presentation shows the current people in the United States of where they are originally from, where they have lived and where they are likely to move next.

The target audience for this visualization are people that are interested in US migration patterns state to state. But also gives a grasp of immigration of outside the country of each state's breakdown in population.

Well Done Static State Bar

While guiding yourself through the interactive visualization, one part of the screen is always fragmented on the top. It tells you which state visualization you currently on, gives a drop down menu to access other states in ascending order.

Geographic State Change

Allows user who is aware of the map of the United States and can geographically pick an individual state that stands out to them in a grander scale.

Yang Hao progress: This week I

  • Created and organized the data sets needed to fulfill the section C requirements.
  • Created the percent() and switch_hour() functions.
  • Finished 5 different tables of data for the Shiny dashboard.
  • Made the dashboard reactive to the hour format and the selected airport and month.
  • Screenshots of the tables I created can be found in this PDF.

Sharable with social Media

Easy Sharability with platforms:

  • Twitter
  • Facebook
  • Pintrest

Just having a cool visualization is useless if you dont have someone to share it with. In this visualization, the creators have targeted famous social medias to help spread their visualization to the world.

Some more platforms they could have included:

  • Google APIs
  • Github or VC for developer uses
  • Data files for open source uses and implementations
  • Design some reactive features for picking date for more information
  • Graph is dynamic for people born in a state vs people that moved to that state

    Each state's information is different based on the people that are born in the state vs people moved there to live there. And depending on what perspective you look at it from, it varies of the information presented to you.


    All graphs are static

    Every state's information is in an ordered form which gives us a huge scrollable selection which can overwhelm the user. Each state contains similar type of information so having a single dynamic graph that changed through a selection process would have benefited in this scenerio.

    What is Exactly Interactive is Unclear.

    The chart above shows that we are able to hover over individual contents of the graph, however also lets the user think it is clickable and give us further information. Also notice that the information is redundant as we hovered over "Born in other states in the Midwest", the hoverable box's only useful information is the percentage, but everything else is already stated.

    The data points are also broken up by decades so the data is scewed to averages rather than precision. If major events happened begining of the decade, and rest of the years didnt have much activity, we cant tell where concentration of data lies.

    It lacks a proper searchability for a specific year, or even comparison to other states directly. The user must locate both charts individually, screenshot and then compare side to side. This puts too much work on the user, and by then the user is uninterested.

    Every Dispora/Migration button says "New"

    The data collected for this study goes until 2012 and above every state's graph there is "new" written. What is new exactly or is this a rushed error that they developers didnt have time to finish. It grabs the attention of the user in a useless way because there is no functionality to this.

    Ads block off features when resizing the visualization

    The application is well made, however if New York Times could provide a proper link to the application which stays away from News article feel. It feels less interactive and more of a article read since so much put on a single page. The ads arent too invasive but distracting and breaks focus on what matters. When we are looking at a visualization, we want to focus on that entirely, not think about tax seasons, or what other articles are available to read next.


    The interactive data visualization was approved by the professor of the course, Dr. Andy Johnson for the Viewer Choice Assignment.

    How the Data/Charts was collected:

    • These charts were compiled using Census microdata obtained from at the University of Minnesota Population Center.
    • These charts were compiled using Census microdata obtained from at the University of Minnesota Population Center.
    • The microdata are records containing the characteristics of individuals compiled from a representative sample of Census forms.
    • The individual, anonymized records are provided by the Census Bureau so researchers can explore the data beyond the published summary tables.

    Data Collecting Reasons/Biases:

    • For domestic migration, the charts look at the place of birth of residents in each state of time.
    • The focus of this report is movement of people from their U.S. state of birth to their U.S. state of residence, foreign born residents were collapsed into a single immigrant category.
    • Likewise, the category “U.S. Other” was created to include residents of states born in Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and a small number of people who in early Census years were identified as being born in Native American tribal territory.
    • Residents classified as U.S. born but without a specific state were allocated a state of birth proportionately based on the make-up of their state of residence for the given year.

    Interesting Findings

    Illinois vs Alabama

    The population of Illinois in 1900 that was living there is 20% of population is born outside the US. This could be for a various amounts of reasons since Civil War ended in 1865 and in the north for states like Illinois was the habbitant of the first accepting non whites and immigrants for their freedom. So the population was 20% which was every 1 in 5 were born outside the country. The number for current population is 15% which infers that over time amd acceptance of other states have let them migrate to different states.

    In retrospect, Alabama is hard sourthern state, shows us that from 1900-1980, the population born outside the country is 1%. Even after the Civil war and until day now, this could infer a variaty of things. That Alabama was known not for colored people or accepting of immigrants. Or that Immigrants and colored people had their own preconceived notions of the Alabama and chose to not live there.

    Racism or acceptance are not the only possible reasons since opportunity in urban areas were more readily available. When immigrants come to this country, they go where the jobs are located and in places they know people in their position have succeeded in the past.


    Nevada vs. California

    The population of native born Nevada in the 1900 that was living there had 25% moved to California. Nevada is mainly a desert state so looking at geographic and environmental advantages that California had to offer was enticing. Nevada and California are also border states so it makes sense that people will want to go where they can get more opportunities and close in distance.

    In retrospect, California in the 1900, residents born in this state: 91% chose to stay here due to its opportunities and resources. However if you look at the current 2010, only 75% of residents live in California. This could be for a variety of reasons like the growth of the Tech hub in california which has caused the rise of cost of living, resources depleting like natural drinking water.

    Also the growth of other metropolitian areas have created more jobs and further more tech hubs like Seatle, Chicago, New York, etc. So maybe the concentration of people that want to live in California is normalizing and spreading to other states.


    Alaska vs. Hawaii

    Here we are given two states that not directly connected to the United States due to their geographic locations. Also keep in mind that the census for the two states are from 1960 and onward. When comparing the populus born outside the country, Alaska at 8% and Hawaii at 20%, it brought up the question why is Hawaii have twice as many immigrants than Alaska.

    • Weather
    • Geographic Location
    • Low Population to Area in Alaska

    The weather in Hawaii is much more tropical and is considered a vacation state in which there is huge economic market for native Hawaians. People dont really travel to Alaska for vacation since its mainly cold and alot of unusable land. Also the plane travel distance from many countries to Hawaii is obtainable but for Alaska, you must do connecting flights since there arent many planes going to Alaska.
