Moving to Opportunity Update

Both the New York Times Upshot and NPR’s Planet Money have stories this morning about Raj Chetty’s Equality of Opportunity Project (previous posted about here).

Diversity and Segregation

Nate Silver of FiveThirtyEight examines urban diversity and segregation:

Chicago deserves its reputation as a segregated city. But it is also an extremely diverse city. And the difference between those terms — which are often misused and misunderstood — says a lot about how millions of American city dwellers live. It is all too common to live in a city with a wide variety of ethnic and racial groups — including Chicago, New York, and Baltimore — and yet remain isolated from those groups in a racially homogenous neighborhood.

The Increase of Singles Changes City Housing

Emily Badger of Wonkblog examines the rising trend of single people living alone and what that will mean for city housing.

Geographical Variations in Equality of Opportunity

Raj Chetty of Harvard has been leading a team of researchers (including former Population Studies Center trainee Patrick Kline) on a project examining the geography of income mobility. From the project website:

Is America the “Land of Opportunity”? In two recent studies, we find that: (1) Upward income mobility varies substantially within the U.S. [summary][paper] Areas with greater mobility tend to have five characteristics: less segregation, less income inequality, better schools, greater social capital, and more stable families. (2) Contrary to popular perception, economic mobility has not changed significantly over time; however, it is consistently lower in the U.S. than in most developed countries. [summary][paper]

Black Immigration to the U.S.

According to a new report from the Pew Research Center, 8.7% of the U.S. black population is foreign born, nearly triple what it was in 1980.

Rapid growth in the black immigrant population is expected to continue. The Census Bureau projects that by 2060, 16.5% of U.S. blacks will be immigrants. In certain metropolitan areas, foreign-born blacks make up a significant share of the overall black population. For example, among the metropolitan areas with the largest black populations, roughly a third of blacks (34%) living in the Miami metro area are immigrants. In the New York metro area, that share is 28%. And in the Washington, D.C., area, it is 15%.

Majority Minority Counties

The Pew Research Center analyzed Census data and found that between 2000 to 2013, 78 counties in 19 states changed from majority white population to populations where no racial or ethnic group is in the majority (their analysis only includes counties with populations of 10,000 or more in 2013).

Millennials and Urban Living

Jed Kolko follows up Ben Casselman’s article Think Millennials Prefer the City? Think Again in FiveThirtyEight with some explanations of why this generation is less urban.

Most urban neighborhoods are not Brooklyn, and most 25- to 34-year-olds don’t have bachelor’s degrees.

Backcasting Native Hawaiian Population

The Pew Research Center Fact Tank examines findings by David Swanson which uses 1910 and 1920 Census data to estimate the population of Hawaii in 1778, the year Capt. James Cook arrived.

In this case, Swanson took a detailed look at the 1910 and 1920 U.S. Census’s Native Hawaiian counts, tracking the survival rate of each five-year age group from one census to the next. For example, he looked at how many children who were newborns to age 4 in 1910 were counted as 10- to 14-year-olds in 1920, then did the same for each successive age group. For each group, he created a “reverse cohort change ratio,” which he used to go back in time and estimate the size of each age group for each decade until he got to 1770.

The article also reports on the growth of the Native Hawaiian population since the 1980s.

Wal-Mart’s Urban Spread

In 2010, 0% of the residents of Washington, DC lived within 2 miles of a Wal-Mart. 5 years later, 41% of residents do. NPR compiled data on the locations of Wal-Marts in Washington, DC, Chicago, and Atlanta and explores what this expansion means for urban neighborhoods. Today’s story focuses on what it means for the workers

PRB Webinar: Mapping Research Approaches to the Demographic Dividend

WHEN: Thursday, Apr. 23, 2015, from 10:00 AM–11:00 AM (EDT) (GMT-4)

From the e-mail:

The demographic dividend offers a powerful argument linking population dynamics and economic development. This topic has attracted a wide variety of researchers and international development organizations and has recently gained traction among global policy audiences. However, research approaches to the demographic dividend are varied and a greater integration of the methodological approaches may be warranted.
