Project Tycho: Historical Disease Data

Project Tycho is funded by NIH and the Bill and Melinda Gates Foundation. It has taken historical data from the National Notifiable Diseases Surveillance System (NNDSS) and created count data for diseases by location for the 125 year history of the surveillance system. Three levels of data have been made available to users from the Project Tycho website.

Other useful resources:

  • Materials and Methods: Digitication of US Weekly Surveillance Reports between 1888 and 2011
  • Preliminary State Reports (scroll down for access – here’s an example for Michigan)
  • What does Tycho stand for?
  • And, here is a paper published in the New England Journal of Medicine based on these data. It estimates that over 100 million cases of contagious diseases have been prevented in the U.S. since 1924 by vaccination programs against polio, measles, mumps, rubella, hepatitis A, diphtheria, and pertussis (whooping cough).

    Elderly Immigrants in the United States

    From the publication website:

    In 2010, more than one in eight U.S. adults ages 65 and older were foreign-born, a share that is expected to continue to grow. The U.S. elderly immigrant population rose from 2.7 million in 1990 to 4.6 million in 2010, a 70 percent increase in 20 years (see figure). This issue of Today‚Äôs Research on Aging reviews recent research examining older immigrants in the United States, conducted by National Institute on Aging (NIA)-supported researchers and others. Understanding both the unique characteristics of elderly foreign-born adults and the challenges some of them face is important as policymakers and planners address the well-being and health of the United States’ aging population.

    The U.S. Foreign-Born Population Ages 65+ Increased Substantially Between 1990 and 2010.

    Demolition as an Urban Strategy

    Via The New York Times
    by: Timothy Williams

    Large-scale destruction is well known in Detroit, but it is also underway in Baltimore, Philadelphia, Cleveland, Cincinnati, Buffalo and others at a total cost of more than $250 million. Officials are tearing down tens of thousands of vacant buildings, many habitable, as they seek to stimulate economic growth, reduce crime and blight, and increase environmental sustainability.

    Visualizing Births and Deaths in Real-Time

    Data visualizations are becoming more and more popular and sometimes they include demographic concepts. The following are two simulations of births and deaths – one for the US and the other for the world.

    Counting Prisoners

    The New York Times had another editorial on this issue:
    Prison-Based Gerrymandering

    September 26, 2013

    A search on its site shows that this has been a common editorial/story topic
    [Counting Prisoners Editorials/Stories]

    The PSC Infoblog has had a previous post on this topic as well, which included the Census Bureau’s response to the issue. The Census Bureau released group quarters data in time for redistricting.

    Another excellent source on this topic is the National Academy of Sciences book, which is available in the PSC library:

    International Migration Statistics for the US

    Here are several links related to international migration in the US from the Census Burea.

    This working paper is relevant for Demographic Analysis – technique used to understand the age, sex, and racial composition of a population and how it has changed over time via births, deaths, and migration. Here is a link to the Demographic Analysis site at the Census Bureau.

    This includes links to an infographic - part of which is included below on America’s foreign born in the last 50 years, data from the American Community Survey on home ownership, STEM degrees, newly arrived, and region-specific reports. There is also a 2010 tables package from the Current Population Survey.

    Big Data Reveals Job Change

    Task Specialization in U.S. Cities from 1880-2000
    Guy Michaels, Ferdinand Rauch, Stephen J. Redding | NBER Working Paper 18715
    January 2013

    In this study, economists Guy Michaels, Ferdinand Rauch, and Stephen J. Redding analyze the verbs used to describe jobs in the U.S. Dictionary of Occupational Titles during a 120 year time period. They do this by geographic area, correlating their findings with the spread of telephone service and transportation networks. They discover “a systematic reallocation of employment over time towards interactive occupations, which involve tasks described by verbs that appear in thesaurus categories concerned with thought, communication and inter-social activity.”

    Using Wild Data to Estimate International Migration

    A previous post described several studies based on non-survey data, which inform demographic events. The following is another very creative example:

    Demography 101: Do not ignore age structure

    In a campaign speech, Romney announced that the unemployment rate was really 11 percent. He was driven to come up with that number since the unemployment rate fell below 8 percent with the October jobs report. But, he made an error. He ignored the changing age structure, e.g., the leading edge of the baby boomers, who have retired.

    This is a good example for a quantitative reasoning class. A fuller explanation of the issue follows in the post by Mulligan.
