Student Diversity at Postsecondary Institutions

The Chronicle of Education has gathered race and ethnicity information on more than 4,600 postsecondary institutions, including undergraduate, graduate, and professional schools and presented it in a searchable and sortable table. Note that the search function is very basic: searching for “Michigan” turns up only schools which start with Michigan (e.g. Michigan State U.), and searching for “University of Michigan” gives no results since it is listed as U. of Michigan. Results can be filtered by state.

IRS Migration Data Report Tool

IRS map

This is a nice tool for getting net migration reports based on IRS tax return data. Note that because these data are based on tax returns, one can also tell whether, on average, a state is losing/gaining wealthier residents. One can generate reports for counties by state or for states. The former is really tedious because one has to generate the county reports one by one.

And here’s the link to raw data for those who find widgets tedious. Note that the site has nice explanations for the methodology, including changes over time in how these files are created: SOI Tax Stats – Migration Data

And, do you want to know how to make something like the map above? Here’s a link from Flowing Data on how to make a similar map based on 5-years of county-to-county IRS data:

The Geography of Prisons Is Changing

Prison populations from big cities have been dropping since 2006, while those from small rural counties have been rising. The New York Times Upshot examines this trend:

Just a decade ago, people in rural, suburban and urban areas were all about equally likely to go to prison. But now people in small counties are about 50 percent more likely to go to prison than people in populous counties.

The stark disparities in how counties punish crime show the limits of recent state and federal changes to reduce the number of inmates. Far from Washington and state capitals, county prosecutors and judges continue to wield great power over who goes to prison and for how long. And many of them have no interest in reducing the prison population.

Creating Residential Histories

This is a report on the NCI/SEERS web portal on a way to create residential histories of respondents/decadents for epidemiological research. The report (below) details how three commercial vendors were able to match the residential history of a small sample of federal government employees. Also available are the algorithms and software to reconcile conflicting addresses. Interested folks might want to browse other tools/papers in the NCI Geographical Information Systems and Science for Cancer Control webiste. https://gis.cancer.gov/index.html

Immigration by Year and Country of Origin

This animated map shows immigration to the United States by year and country of origin:

From 1820 to 2013, 79 million people obtained lawful permanent resident status in the United States. The interactive map below visualizes all of them based on their prior country of residence. The brightness of a country corresponds to its total migration to the U.S. at the given time.

What Is “Normal America”?

Jed Kolko looked the demographics of each U.S. metropolitan area and measured how demographically similar they are to the U.S. as a whole, based on age, educational attainment, and race and ethnicity: “But that sense that the normal America is out there somewhere in a hamlet where they can’t pronounce “Acela” is misplaced. In fact, it’s not in a small town at all.”

Older Women Living Alone

Philip Cohen of the Family Inequality blog highlights a new Pew Research Center report on the share of U.S. women aged 65 and older living alone. The main finding of the report is that the number of women in this age group living alone has been trending downward since 1990. Pew attributes this to longer life expectancy for men, but Cohen thinks something more may be going on:

The tricky thing about this is the changing age distribution of the old population (the Pew report breaks the group down into 65-84 versus 85+, but doesn’t dwell on the changing relative size of those two groups).

Public Opinion on Abortion

The Pew Research Center recently did a survey on abortion. Views have remained quite stable for the last 20 years: in 1995, 60% of Americans believed abortion should be legal in most cases and 38% believed it should be illegal, and in 2016, 56% believe it should be legal and 41% believe it should be illegal.

Worldwide Gender Gap in Religion

The Pew Research Center released a new study on gender and religion, finding that women are generally more religious than men.

Standard lists of history’s most influential religious leaders – among them Abraham, Moses, Jesus, Muhammad, Siddhartha Gautama (the Buddha) – tend to be predominantly, if not exclusively, male. Many religious groups, including Roman Catholics and Orthodox Jews, allow only men to be clergy, while others, including some denominations in the evangelical Protestant tradition, have lifted that restriction only in recent decades. Yet it often appears that the ranks of the faithful are dominated by women.

An Aging World: 2015

The U.S. Census Bureau released its newest report on aging, An Aging World: 2015.

The world population continues to grow older rapidly as fertility rates have fallen to very low levels in most world regions and people tend to live longer. When the global population reached 7 billion in 2012, 562 million (or 8.0 percent) were aged 65 and over. In 2015, 3 years later, the older population rose by 55 million and the proportion of the older population reached 8.5 percent of the total population.
