From the Population Reference Bureau:
The number of international migrants more than doubled between 1980 and 2010, from 103 million to 220 million. In 2013, the number of international migrants was 232 million and is projected to double to over 400 million by 2050.

Seven of the 15 fastest growing cities in America are in the booming state of Texas, according to the annual ranking released today by the U.S. Census Bureau.
And three of those eight are in the vicinity of Austin, the state’s capital city.
One of those three, San Marcos, population 54,076, holds the distinction of being the fastest-growing city for two consecutive years. Its population increased by 8 percent between July 2012 and July 2013 — the period covered by the survey. It grew 44 percent in the past 15 years.

Malawi’s Pathway to a Demographic Dividend.
“Over the past decade, countries throughout Africa have experienced sustained economic growth. Despite this growth, almost two of every three people—or 600 million—are still living on less than $2 per day. Like many of its neighbours, Malawi experienced consistent economic growth during the mid-2000s, though this growth had little effect on poverty.”

Millions of Americans counted in the 2000 census changed their race or Hispanic-origin categories when they filled out their 2010 census forms, according to new research presented at the annual Population Association of America meeting last week. Hispanics, Americans of mixed race, American Indians and Pacific Islanders were among those most likely to check different boxes from one census to the next.

The main objective of the decomposition tool is to provide evidence and analysis that countries can use to develop policies and programmes aimed to find a balance between demographic change and social, economic and environmental goals.
This program calculates the contributions of different demographic factors (wanted and un-wanted fertility, mortality, migration, and age structure) to population growth. It is based on the medium variant population projection of the United Nations from 2010 to 2050 for all countries and main regions.
Select a country or region from the window below to view the results of the decomposition tool. Move mouse over the figures to explore the interactive data content. Then read and download a report summarizing the results, methods, and policy implications.

Blexting is short for “blight texting.” It is an app that a Detroit-based start-up (Loveland Technologies) created, which is being used to map all Detroit structures to fight blight. Here’s a bit of the coverage of the software and the amazing progress the blexters have made in mapping Detroit blight:

In the nation’s debate about the minimum wage, which President Obama has proposed increasing at the federal level to $10.10 from $7.25, this rolling borderland of onion farms and strip malls provides a test tube of sorts for observing how the minimum wage works in daily life, and how differences in the rate can affect a local economy in sometimes unexpected ways.

The Census Bureau has released county to county migration flow data from the 2007-2011 ACS. This allows researchers to look at outbound, inbound, and net migration flows by selected characteristics (education, household income, and individual income).
Perhaps, Governor Snyder had advance access to these data before his state-of-the-state address as the only positive net value for Wayne County (and Michigan) is “movers from abroad.” Wayne County has a net loss of 28,000 to other Michigan counties and a net loss of approximately 17,000 to out of state counties. It has about one-third of Michigan’s movers from abroad (7,620 out of 24,715).

Project Tycho is funded by NIH and the Bill and Melinda Gates Foundation. It has taken historical data from the National Notifiable Diseases Surveillance System (NNDSS) and created count data for diseases by location for the 125 year history of the surveillance system. Three levels of data have been made available to users from the Project Tycho website.

And, here is a paper published in the New England Journal of Medicine based on these data. It estimates that over 100 million cases of contagious diseases have been prevented in the U.S. since 1924 by vaccination programs against polio, measles, mumps, rubella, hepatitis A, diphtheria, and pertussis (whooping cough).
