Mapping Twitter Topic Networks: From Polarized Crowds to Community Clusters
Conversations on Twitter create networks with identifiable contours as people reply to and mention one another in their tweets. These conversational structures differ, depending on the subject and the people driving the conversation. Six structures are regularly observed: divided, unified, fragmented, clustered, and inward and outward hub and spoke structures. These are created as individuals choose whom to reply to or mention in their Twitter messages and the structures tell a story about the nature of the conversation.

From the new DHS Program blog:
[So in 2013,] when USAID’s MEASURE umbrella ceased to be, it was clear that we needed to be something more than simply “DHS”. But what? At first glance, “The Demographic and Health Surveys Program” or “The DHS Program” seems like an innocuous project name. But to us, it represents a lot more.
As a Program, we are representing not one contract with USAID, but 30 years of data collection in more than 90 countries.
As a Program, we are not just our flagship household survey, but a suite of surveys, data management, biomarker testing and GIS and research activities.
As a Program, we encompass far more than just data collection, but are charged with strengthening capacity, communicating complex information, analyzing data, and ensuring that DHS data are used to inform decisions all over the globe to improve the health of families and communities.

From the UNFPA website:
The main objective of the decomposition tool is to provide evidence and analysis that countries can use to develop policies and programmes aimed to find a balance between demographic change and social, economic and environmental goals.
This program calculates the contributions of different demographic factors (wanted and un-wanted fertility, mortality, migration, and age structure) to population growth. It is based on the medium variant population projection of the United Nations from 2010 to 2050 for all countries and main regions.
Select a country or region from the window below to view the results of the decomposition tool. Move mouse over the figures to explore the interactive data content. Then read and download a report summarizing the results, methods, and policy implications.
Learn more and use the tool on the website.
Researchers will now have access to genetic data linked to medical information on a diverse group of more than 78,000 people, enabling investigations into many diseases and conditions. The data, from one of the nation’s largest and most diverse genomics projects — Genetic Epidemiology Research on Aging (GERA) — have just been made available to qualified researchers through the database of Genotypes and Phenotypes (dbGaP), an online genetics database of the National Institutes of Health.

Minority Male Students Face Challenge to Achieve at Community Colleges
Although black and Latino male students enter community colleges with higher aspirations than those of their white peers, white men are six times as likely to graduate in three years with a certificate or degree, according to a report released on Wednesday by the Center for Community College Student Engagement at the University of Texas here.

Why should NSF fund political science? Here’s a great reason:
United States Congressional District Shapefiles
Jeffrey B. Lewis, Brandon DeVine, and Lincoln Pritcher with Kenneth C. Martis
This site provides digital boundary definitions for every U.S. Congressional District in use between 1789 and 2012. These were produced as part of NSF grant SBE-SES-0241647 between 2009 and 2013.
The current release of these data is experimental. We have had done a good deal of work to validate all of the shapes. However, it is quite likely that some irregularities remain. Please email firstname.lastname@example.org with questions or suggestions for improvement. We hope to have a ticketing system for bugs and a versioning system up soon. The district definitions currently available should be considered an initial-release version.
The FY2014 budget for BLS has cut two important data programs: The Quarterly Census of Employment and Wages and the International Price Program. The latter is a principal economic indicator.

Blexting is short for “blight texting.” It is an app that a Detroit-based start-up (Loveland Technologies) created, which is being used to map all Detroit structures to fight blight. Here’s a bit of the coverage of the software and the amazing progress the blexters have made in mapping Detroit blight:

Bob Groves is no longer the Census Bureau director, but the Census Bureau’s plans for the 2020 Census have many of the elements that he wrote about in the Census Bureau’s Director’s blog and presented at professional meetings. He has had a lasting impact at the Census Bureau.

Finally, the reference to “updated guidance” in the Pew piece sounds quite a bit like paradata used in responsive survey design of the NSFG. The Census enumerates all households so it isn’t a survey, but paradata can guide the data collection process – when to enumerate (weekend or not, evening or not) and when to get data from other sources.

Here are two reports on inequality – one for states, including historical data and one for the 50 largest cities. The state-based analysis uses state-level tax data whereas the city-based analysis uses the American Community Survey. The city-based study is referenced in a story in the New York Times.
