Welcome to the CDXZipStream April 2012 Newsletter

We've just updated our demographic data feeds from the American Community Survey, which now covers over 29,500 cities across the U.S., and our new video tutorial covers various CDXZipStream functions that incorporate postal codes in Canada. Also, here are our latest blog postings:

The American Community Survey Now Covers Over 29K Cities

 American Community Survey 

We have just updated our data feeds associated with the American Community Survey, which are available with the Premium ACS version of CDXZipStream.  This is the first time the Census Bureau has issued ACS data aggregated over five years (2005 - 2009), which means it covers a lot more smaller geographies in the U.S.  For example, the number of cities included in the survey has increased from 2,100 to over 29,500.  To see all the geographies now covered in our ACS data feeds, please download our ACS Support Data file.


If you're not familiar with the American Community Survey, it is administered by the U.S. Census Bureau to about 3 million households each year.  It has replaced the old "long form" that was last used with the 2000 Census. So instead of being a single snapshot of the U.S. population taken every ten years, it's a continuously updated, ongoing survey that's a terrific source of social, economic, and housing information.  Subject areas covered by our data feeds are:  population, age, race, educational attainment, school enrollment, housing value, rental rates, household income, earnings by gender, household size, and marital status. Please refer to the file CDXZipStream Data Feeds and Definitions for a list of all data fields.


If you already have the ACS Premium version, you can get the updated ACS feeds by purchasing a data update, priced at $29.95.  Just click on the "License Information and Software Updates" icon on the CDXZipStream toolbar, and select "Data Updates" to login to your account and purchase an update.  (Your user name is usually the email address you used to purchase the software, but contact us at if you have a problem.)  You can then select the "Product Management" under the My Account area of our website (on the left-side menu), and click on "Download Data Files" to download and install the new database.  Alternatively, you can also click on "Buy Data Updates" here to purchase updates.  If you have another version of CDXZipStream and would like to upgrade to ACS Premium, you can also purchase the upgrade through your online account.  Please see our price list at the bottom for upgrade pricing.


The Census Bureau has stated it will be issuing zip code -based data from the ACS with the next update for 2006-2010, and we will be adding this as a new data feed in the future.  Stay tuned!


Our Canadian Database in Action


The Canadian postal code database introduced last year in Version 11 has been a popular option for CDXZipStream users.  The database covers over 850,000 codes and works with several CDXZipStream functions, allowing you to do postal code lookup and list generation, as well as distance and radius calculations for locations in Canada.  We've recently created a new video tutorial, showing how it works with functions such as CDXDistance, CDXFindZip, and CDXClosestZip:

The new database is priced at $99.95 and can be downloaded with any new purchase of CDXZipStream from our "Buy Now" webpage.  If you already own a version of CDXZipStream, the Canadian database can be purchased from your online account.  You must also install our (free) latest version of CDXZipStream (Version 11).


Note that routing and other calculations associated with the functions CDXRouteMP and CDXLocateMP use the Microsoft MapPoint database for North America and have always covered Canada.


April Data Updates


Canadian and U.S. data feeds were updated as of April 26.  There were 59 changes to the U.S. zip code database.  If you would like to update your database to reflect these changes, click on the "License Information and Software Updates" icon on the CDXZipStream toolbar, and select "Data Updates" to login to your account.  If you've forgotten your user name or password, please contact us at


We hope you find the information here helpful for you and your organization.  Please contact us with your feedback and suggestions by replying to this email.
