From US Census Bureau - Release of 2008-2010 ACS 3-Year Estimates

We are pleased to announce the release of the 2008-2010 American Community Survey (ACS) 3-Year Estimates, the most
relied-upon source for up-to-date socioeconomic information every year. The release covers more than 40 topics,
such as educational attainment, income, health insurance coverage, occupation, language spoken at home, nativity,
ancestry and selected monthly homeowner costs. The estimates are available in detailed tables for the nation, all
50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all
counties and places with populations of 20,000 or more.

Beginning in 2008, the ACS questionnaire included new questions about marital history, disability, health insurance,
and service-connected disability-rating status and ratings for civilian veterans. The 2008-2010 ACS 3-Year Estimates will
be the first 3-year dataset to include this new content. To learn more about these tables, and other data product
changes, please visit our 2010 Data Product Changes page.

To find statistics for your area, visit the Census Bureau's American FactFinder.

From Revolution Analytics: Webinar Series: Next Up "Scalable Data Analysis in R" Oct 26th, 10-11AM Pacific Time

Revolution Analytics would like to invite you to attend our 2011 Fall Webinar Series. Coming up Wednesday, October 26th is "Scalable Data Analysis is R", presented by Lee Edlefsen, Ph.D., Chief Scientist at Revolution Analytics.

For the past several decades the rising tide of technology -- especially the increasing speed of single processors -- has allowed the same data analysis code to run faster and on bigger data sets. That happy era is ending. The size of data sets is increasing much more rapidly than the speed of single cores, of I/O, and of RAM. To deal with this, we need software that can use multiple cores, multiple hard drives, and multiple computers. That is, we need scalable data analysis software.

R is the ideal platform for scalable data analysis software. It is easy to add new functionality in the R environment, and easy to integrate it into existing functionality. R is also powerful, flexible and forgiving.
In this webinar, Dr. Edlefsen will discuss the approach to scalability Revolution Analytics has taken with its RevoScaleR package. He will discuss this approach from the point of view of:

* Storing data on disk
* Importing data from other sources
* Reading and writing of chunks of data
* Handling data in memory
* Using multiple cores on single computers
* Using multiple computers
* Automatically parallelizing "external memory" algorithms

From US Census Bureau - 2010 American Community Survey 1-Year PUMS

We are pleased to announce the release of the 2010 American Community Survey (ACS) 1-Year Public Use Microdata Sample
(PUMS) files. PUMS files from the ACS show the full range of population and housing unit responses
collected on individual ACS questionnaires. These files enable users to design tabulations that aggregate responses
differently than the published data products.

The PUMS files contain records for a subsample of ACS housing units and group quarters persons. As required by federal law,
the confidentiality of ACS respondents is protected through a variety of steps to disguise or suppress original data while
making sure the results are still useful. In addition to modifying the individual records, respondents' confidentiality is
protected because only large geographic areas are identified in the PUMS. To read more about how the PUMS files are created,
browse code lists, and look-up subjects in the PUMS, please visit the PUMS Documentation Page.

The PUMS data is accessible now via the FTP site. Links can be found on our PUMS Data Page.
On October 27, 2011 the data will also be accessible via American FactFinder.

If you need information or have questions about the survey, please call our Customer Services Center on 1 (800) 923-8282.

From IES Newsflash: NCES Report Analyzes Use of Private Loans in Postsecondary Education

A new report on postsecondary private loan borrows found that the percentage of undergraduates who took out private loans rose from 5 percent to 14 percent from 2003–04 to 2007–08.

The Expansion of Private Loans in Postsecondary Education, a Statistics in Brief, examines trends in borrowing from commercial lenders for postsecondary education, the characteristics of undergraduate and graduate private loan borrowers, and combining private and federal loans. Results are based on nationally representative data collected through the 2003–04 and 2007–08 National Postsecondary Student Aid Studies (NPSAS:04 and NPSAS:08).

Other findings include:

• Among full-time dependent undergraduates, higher percentages of students from lower middle-income (21 percent) and upper middle-income (20 percent) families than students from low-income (15 percent) or high-income (16 percent) families borrowed private loans in 2007–08.

• The largest proportion of borrowers who took out private loans either exclusively or in combination with public loans (42 percent) was found among those enrolled at for-profit institutions in 2007–08.

• Among dependent private loan borrowers, 53 percent had also borrowed the maximum federal Stafford loan amount.

This Statistics in Brief is a product of the National Center for Education Statistics at the Institute of Education Sciences, part of the U.S. Department of Education.
