Newest New Yorkers

The New York City Planning Department released the latest in its Newest New Yorker series. The 2013 edition, The Newest New Yorkers: Characteristics of the City’s Foreign-born Population, builds on the earlier edition, and provides detailed analyses of the newest data from the U.S. Census American Community Survey. There is also an interactive map showing the immigrant make-up of each of New York’s neighborhoods.

Big data and smart cities

Urban Demographics posted a presentation by Rob Kitchin based on his paper “The real-time city? Big data and smart urbanism” (gated version; working paper version).

Abstract:

‘Smart cities’ is a term that has gained traction in academia, business and government to describe cities that, on the one hand, are increasingly composed of and monitored by pervasive and ubiquitous computing and, on the other, whose economy and governance is being driven by innovation, creativity and entrepreneurship, enacted by smart people. This paper focuses on the former and, drawing on a number of examples, details how cities are being instrumented with digital devices and infrastructure that produce ‘big data’. Such data, smart city advocates argue enables real-time analysis of city life, new modes of urban governance, and provides the raw material for envisioning and enacting more efficient, sustainable, competitive, productive, open and transparent cities. The final section of the paper provides a critical reflection on the implications of big data and smart urbanism, examining five emerging concerns: the politics of big urban data, technocratic governance and city development, corporatisation of city governance and technological lock-ins, buggy, brittle and hackable cities, and the panoptic city.

Mapping Race in the U.S.

Nathan Yau of Flowing Data created an interactive map showing the concentrations of Whites, Hispanics, Blacks, Asians, Native Americans, and Pacific Islanders at the county level.

The map above shows the most prevalent race in each county, based on data from the 2013 American Community Survey 5-year estimates. Select and deselect to make various comparisons. Or, select just one race to see distribution. Low, medium, and high saturation indicates whether the prevalent race percentage is below or about the same, higher (greater than the national average plus-minus interval), or much higher than the national average (at least 50% higher), respectively.

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

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]
