Mean Age of Mothers, 2010 – 2014

Mean and average age: The arithmetic average of a mother’s age at birth.

First birth: The first child born alive to a mother.

Race and Hispanic origin: Race and Hispanic origin are reported separately on birth certificates. Persons of Hispanic origin may be of any race. Persons of non-Hispanic ancestry are further classified by race because there are substantial difference in fertility and maternal characteristics between Hispanic and non-Hispanic persons. Persons of AIAN and API ancestry are not classified separately by Hispanic origin because the majority of these persons are non-Hispanic. Multiple-race data reported since 2003 were bridged to single race categories for comparability among states and for trend analyses.

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.

The Duncan & Trejo paper can be found here.

More On Poverty and Financial Literacy

Sendhil Mullainathan writes about the lessons the rich can learn from the poor about frugality for the Upshot.

Consider this situation: You’re shopping for headphones. An electronics store has the model you want for $50, a reasonable price. But a sales clerk says: “You know our other branch has this item on sale for $40.” Going to that store will take 30 minutes, and you can’t buy the headphones for that price online. Do you go to the other branch?

Before you answer, consider a slightly modified version of the same situation: Instead of headphones, you are buying speakers. You go to the same store and find the model you want for $400. Again, the price seems reasonable but the sales clerk says it’s on sale at the other branch for $385. What do you do now?

This is covering the same research as the earlier Wonkblog article.

Predicting Crime

Maurice Chammah, writing for The Marshall Project, writes about the St. Louis police departments’ use of crime-predicting software.

HunchLab, produced by Philadelphia-based startup Azavea, represents the newest iteration of predictive policing, a method of analyzing crime data and identifying patterns that may repeat into the future. HunchLab primarily surveys past crimes, but also digs into dozens of other factors like population density; census data; the locations of bars, churches, schools, and transportation hubs; schedules for home games — even moon phases. Some of the correlations it uncovers are obvious, like less crime on cold days. Others are more mysterious: rates of aggravated assault in Chicago have decreased on windier days, while cars in Philadelphia were stolen more often when parked near schools.

Promoting Your Research

Philip Cohen of Family Inequality has some suggestions for promoting your research:

These are some basic thoughts for academics promoting their research. You don’t have to be a full-time self-promoter to improve your reach and impact, but the options are daunting and I often hear people say they don’t have time to do things like run a Twitter account or write blogs. Even a relatively small effort, if well directed, can help a lot. Don’t let the perfect be the enemy of the good. It’s fine to do some things pretty well even if you can’t do everything to your ideal standard.

It’s all about making your research better — better quality, better impact. You want more people to read and appreciate your work, not just because you want fame and fortune, but because that’s what the work is for.

Changes in Incarceration Rates

Keith Humphreys, writing for WonkBlog, examines recent changes in the U.S. incarceration rates:

After decades of growth, the U.S. imprisonment rate has been declining for the past six years. Hidden within this welcome overall trend is a sizable and surprising racial disparity: African-Americans are benefitting from the national de-incarceration trend but whites are serving time at increasingly higher rates.
