Population Trends in U.S. Cities

A new U.S. Census Current Population Report (PDF) examines the ways populations in U.S. cities changed between 2010 and 2013.

From the introduction:

Nearly two-thirds of Americans live in incorporated places, commonly referred to as cities. As the majority of the nation’s population lives in cities, patterns of population change among cities and the social and economic conditions affecting them often represent national trends. Using data from the 2000 and 2010 censuses and 2013 population estimates, this report examines the population in cities and highlights how city populations changed between 2000 and 2010, and between 2010 and 2013. The report discusses the distribution of the population in cities by region, state, and city population size. It also highlights the fastest growing cities, city population densities, annexation, and new incorporations between 2010 and 2013.

The New York State Data Center Affiliates wrote this report up in a March 4 post for their Data Detectives blog.

Time Use of the Nonemployed

Josh Katz of the NYTimes blog The Upshot pulled data from the American Time Use Survey to examine how nonemployed men and women spend their weekdays:

Nonworkers spend much more time doing housework. Men without jobs, in particular, spend more time watching television, while women without jobs spend more time taking care of others. And the nonemployed of both sexes spend more time sleeping than their employed counterparts.

Trends in Religious Restrictions and Hostilities

The Pew Research Center has released a new report (PDF) analyzing governmental and societal impingement on religious beliefs and practices.

This article looks at the overall trends. And this article examines the restrictions and hostilities in the most populous countries.

The Economics of Unplanned Pregnancies

Christopher Ingraham of Wonkblog examines a new report from the Guttmacher Institute showing that unintended pregnancies cost the U.S. $21 billion each year:

Nationally there were 1.5 million unplanned births in 2010. Public insurance programs like Medicaid paid for 68 percent of those births. “On average, a publicly funded birth cost $12,770 in prenatal care, labor and delivery, postpartum care and the first 12 months of infant care; care for months 13–60 cost, on average, another $7,947, for a total cost per birth of $20,716,” the study found.

Education and Health

The Connector, the NIH OBSSR’s blog, has a couple of posts examining the links between education and health. The first one, Contextualizing the link between education and health, discusses the results of a partnership between the NIH Office of Behavioral and Social Sciences Research and Harvard Center for Population and Development Studies which resulted in two workshops and a special issue of Social Science and Medicine, “Educational Attainment and Adult Health: Contextualizing Causality“.

In the second post, Compulsory schooling and health: What the evidence says, Lauren Fordyce looks at the impact of compulsory education on health outcomes.

Another take on gentrification

Gentrification in America Report
Mike Maciag | Governing
February 2015
This resource is city-specific and provides both counts and maps of gentrified census tracts for the 50 largest cities. To be eligible for gentrification a census tract’s median household income and median home value were both in the bottom 40th percentile of all tracts within a metro area at the beginning of the decade. The gentrified tracts recorded increases in the top third percentile for both measures when compared to all others in a metro area.

Methodology

And more broadly, this resource has a special issue on gentrification:

The titles in this series are:
Do Cities Need Kids?
The Neighborhood Has Gentrified, But Where’s the Grocery Store?
Just Green Enough
Gentrification’s Not So Black and White After All

Geography of Class, Education, and Income in the United States

ArcGIS has three interactive maps showing “the current occupational class, income and educational landscape across the United States. These maps allow the user to explore the various socio-economic divides that exist in our cities and towns at the census tract level.”

The Hedometer Index

This is an index of happiness created from tweets. The index provides a daily score, which can be toggled to exclude weekends, Mondays, etc.

Hedometer Index

This is an excellent resource because the creators of this happiness index describe the calculation of the index, the words used in it, provide an API, have links to articles based on the index, etc. It is a valuable resource, even if you do not care about happiness as it provides a template for many other uses of data from Twitter.

Instructions [Documenation of index via video or written - click on links]
Words [Words used in index, ranks, etc.]
Blog [The Computational Story Lab. . . mostly related to happiness]
Press [press coverage]
Papers [refereed papers by research team]
Talks [maybe you need a clip for a lecture]
API [lots of examples]

Move over Index of Consumer Sentiment/Expectations?

I ran across this in the Wall Street Journal (slide 58 of 93):

Can happiness from tweets reduce drawdowns from selling VIX?

Selling VIX futures has been profitable historically. However, the strategy can be subject to drawdowns, when there is risk aversion . . . . Using the Hedometer index as an input, we have created a Happiness Sentiment Index (HSI), which can be sued to proxy market risk sentiment. . . .

HSI index
