Nathan Yau of Flowing Data set out to recreate the original 56 page Statistical Atlas of the United States, first published in 1874 using 1870 Census data. Yau’s version uses current, publicly available government data.
Nathan Yau of Flowing Data discusses the handful of rules for charts and data visualization which should never be broken. These include baselines, pie slices, and encodings.
The NYC Planning Department’s American Community Survey update to the NYC Census Factfinder application has been released. It is now possible to get 2009-2013 ACS profiles for Neighborhood Tabulation Areas and user defined census tract aggregations, in addition to demographic profiles from the 2000 and 2010 censuses.

Flowing Data points out two useful data resources:
Researchers at the University of North Carolina at Chapel Hill are working on a project called DataBridge to create an archive for data sets and metadata that would otherwise be lost once the papers they were produced for are published.
The U.S. Census Bureau released revised estimates and projections for 24 countries, including China, Iraq, Malawi, South Africa and United States. See the release note tab for a full list of revised countries.
‘Smart cities’ is a term that has gained traction in academia, business and government to describe cities that, on the one hand, are increasingly composed of and monitored by pervasive and ubiquitous computing and, on the other, whose economy and governance is being driven by innovation, creativity and entrepreneurship, enacted by smart people. This paper focuses on the former and, drawing on a number of examples, details how cities are being instrumented with digital devices and infrastructure that produce ‘big data’. Such data, smart city advocates argue enables real-time analysis of city life, new modes of urban governance, and provides the raw material for envisioning and enacting more efficient, sustainable, competitive, productive, open and transparent cities. The final section of the paper provides a critical reflection on the implications of big data and smart urbanism, examining five emerging concerns: the politics of big urban data, technocratic governance and city development, corporatisation of city governance and technological lock-ins, buggy, brittle and hackable cities, and the panoptic city.
The University of Michigan Library has just acquired access to Sage Stats, a resource for local area statistics:
Sage Stats features data series on U.S. states, counties, cities, and metropolitan areas. Topics covered include the economy, education, crime, government finance, health, population, religion, social welfare, and transportation. Some series go back more than 20 years. Sage Stats makes it easy to download data, compare indicators or create simple visualizations of local area data.
Access is available to the Ann Arbor, Flint and Dearborn campuses at
The Apple Research Kit allows researchers to develop an iPhone app, which interested respondents can download from the Apple Store. The respondent goes through an on-line consent form and then responds to questions, tasks (walking), etc. Some of the diagnostic tools are based on previously developed apps from the Apple Healthkit.
As of now, apps have been developed for collecting data for research projects on asthma, cardiovascular disease, diabetes, Parkinson’s, mind, body, and wellness after breast cancer, and for a population-based study, the LGBTQ population.
Here is a description of the informed consent process for these iPhone apps:
Participant-Centered Consent Toolkit
Listed below are a few press releases associated with the Pride Study – the population based study of the gay population. Following those posts are some more general critiques of this way of gathering data. The post from the Verge is probably the most critical raising issues of “on the internet no one knows you are a dog” and gaming the consent process (lying about eligibility for the study). On the plus side, the participant pool is going to be easier to sign up and won’t be limited to those who live close to research hospitals. Here is an excerpt from Business Insider to the reaction to the app launch for the Stanford Heart study:
It’s really incredible … in the first 24 hours of research kit we’ve had 11,000 people sign up for a study in cardiovascular disease through Stanford University’s app. And, to put that in perspective – Stanford has told us that it would have taken normally 50 medical centers an entire year to sign up that many participants. So, this is – research kit is an absolute game changer.
The participant pool is limited to iPhone users (no android version of these apps), although some will have a web interface (the Pride Study).
