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.

Pre-WWII Segregation In U.S. Cities

Emily Badger of Wonkblog, examines a paper by Allison Shertzer and Randall P. Walsh about how the arrival of blacks in 10 northern cities between 1900 and 1930 caused whites to sort themselves into different neighborhoods.

In their new research, they studied how the arrival of blacks in 10 northern cities at the time influenced white behavior. Over the course of the first three decades after the turn of the century, coinciding with the start of the Great Migration of blacks out of the South, this pattern accelerated: As blacks arrived in northern neighborhoods, more whites left. By the 1920s, there were more than three white departures for every black arrival.

Mixed Marriage and How We Think About Race

Jeff Guo of Wonkblog examines research showing trends in how children of mixed marriages report their own race to the Census Report.

In fact, new immigrants may be assimilating a lot faster than than we had ever thought. A new study this week from economists Brian Duncan, of the University of Colorado, and Stephen Trejo of University of Texas, Austin finds that the descendents of immigrants from Latin-American and Asian countries quickly cease to identify as Hispanic or Asian on government surveys.
