Welcome to the CDX Technologies February 2018 Newsletter


We've updated our premium demographic feeds so that the data now reflect the latest information from the U.S. Census American Community Survey (ACS). Also covered is a new free resource for a ZIP Code Radius Report now available in the "Tools" menu on our website.


Here is our latest blog posting:


ACS Data Feeds Updated with Latest Census Data


The CDXZipStream ACS data feeds for state, county, ZIP code (ZCTA), place, and CBSA (Core-Based Statistical Area) have been updated with the latest data releases from the U.S. Census Bureau. These data are from the American Community Survey, which surveys about 1 out of every 38 households every year. These feeds are available in the CDXZipStream Premium ACS version. 


Data for all geographies are aggregated over the years 2012 through 2016, except for states which are derived from the 2016 survey. 


The demographic areas covered in all ACS feeds are: age, population, household size, household income, individual earnings, race and ethnicity, educational attainment, school enrollment, housing value and rent, mortgage status, and marital status. For a full listing of all data fields included in the feeds, please download the CDXZipStream Data Feeds and Definitions file here


If you already own CDXZipStream ACS Premium, you can update your data feeds by logging into your on-line account on and under My Account and Product Management, selecting "Buy Data Update".   To upgrade your current license to the CDXZipStream ACS Premium version, select "Upgrade License" in the account area and follow the purchasing process. The latest data will automatically be included with your purchase. 


Get the Latest ACS Data by Census Tract  


We've also updated the CDXZipStream Census Tract data feed from the American Community Survey, with data aggregated over the years 2012-2016.  The feed includes all census tracts in both the U.S. and Puerto Rico, and covers a wide array of demographic data such as:  age, individual earnings, educational attainment, household size, household income, housing value and rent, marital status, population, race, and school enrollment.  Most of these where relevant are also provided by gender. 


To access the data, census tract codes (also referred to as FIPS codes) must be provided as input to an Excel worksheet.  CDX Technologies also offers a free Excel template that can identify census tract codes for an address list - please see the article Get Census Tract FIPS Codes in an Excel Template for more details. 

Since census tracts are on average about half the size of ZIP Codes, they offer a more precise demographic snapshot.


The census tract database is compatible with all demographic versions of CDXZipStream.  It is a separate purchase and is currently priced at $199.95.


New Cloud-Based Radius Analysis Tool 


We've just released a new free tool on our website, ZIP Code Radius Report.  This application operates independently of Excel and does not require a CDXZipStream license.


This software tool will allow you to find all U.S. ZIP codes within a given radius. Just enter your central ZIP code, specify a distance and press the "Generate Report" button. The distance can be optionally specified in miles, kilometers or nautical miles. A radius of up to 30 miles can be generated in the free tool. The report contains the distance, latitude, and longitude and distance type. Click on the down arrow next to the "Generate Report" button on the report screen to download the data in csv format.


Latest Data Updates


Canadian and U.S. data feeds of CDXZipStream were updated as of February 26.  There were 832 changes made to the U.S. ZIP Code database this month.  If you would like to update your database to reflect these changes, select the "Account" option on the CDXZipStream commandbar and click on "Check for Available Database Updates".  You can then update each database as required.  Please note that updates for the classic version of CDXZipStream have been discontinued.


CDXZipStream updates are a part of the one-year software maintenance subscription included with your purchase.  If you would like to extend your subscription, please sign in to the CDX Technologies website and from the account area for CDXZipStream, select "Buy Data Update".
