Neighborhood Change Database (NCDB) 2010 Now Available from GeoLytics

The Neighborhood Change Database 2010 has Census Tract data from 1970, 1980, 1990, 2000, and 2010.  In addition to having the data in the year-specific boundaries it also has them all normalized to the 2010 tract boundaries.  This means that you can easily explore changes in U.S. demographics from 1970 to 2010 all in the same geographic boundary definitions.  The power of this database comes from cross-walking the 1970, 1980, 1990, and 2000 census data to 2010 census tract boundaries, meaning that you can do a real apples-to-apples comparison for the data without having to make accommodations for the changing boundaries – we’ve already done that for you. 

With the Neighborhood Change Database researchers can examine population transformations in urban communities over 50 years.  With GeoLytics’ proprietary block weighting algorithms, you get accurate calculations for comparing census tract data from the 1970 through 2010 census in a uniform set of boundaries.  For more information go to:
http://www.geolytics.com/USCensus,Neighborhood-Change-Database-1970-2000,Data,Features,Products.asp

For added flexibility we have also included the 1970-80-90-2000 data in their year specific tract boundaries.

GeoLytics and the Urban Institute developed the Neighborhood Change Database, with partial funding by the Rockefeller Foundation.  It combines tract level data from the 1970 through 2010 decennial censuses.  The NCDB 2010 has 2010 data from both the Summary File 1 (SF1) and the American Community Survey (ACS) databases. 
There are 568 variables from the SF1 and an additional 1,625 from the 2006-2010 ACS data file.  Similarly there are 1,800 variables from the 2000 Census Long Form (SF3), 1,100 variables from the 1990 Long Form, 1,100 variables from the 1980 Long Form, and
800 variables from the 1970 Long Form.  For a complete list of variables go to:

Like all of our Census products, the Neighborhood Change Database has functional mapping capabilities and easily exports geographic tract boundaries.  You can also export the data as a dbf or csv file to easily use in a database or statistical software package.

Easy Zip+4 Analysis – Now Available from GeoLytics

Our new 2013 Zip+4 product will providethe area centroid of each of the 35+ million zip+4s with latitude/longitude coordinates and assigns the 2010 block, block group, tract, and county identification numbers/FIPS code.  Then it appends data for the Block Group in which that zip+4 is located.  The standard version has a sample of demographic variables from the Census 2010 Summary File 1 and American Community Survey. The expanded Zip+4 includes all of these variables as well as data from our 2013 Estimates and 2018 Projections.

Our Zip+4 product was designed to access the data in two distinct ways.  First, you can upload a file into it and secondly you can download a database file from it.  The first mode is designed for the user who wants to profile customer/client lists.  This product will allow you to upload your file of zip+4’s and automatically append the appropriate data to each entry.  The second option of downloading a database file is ideal for the user who wants to “hit” against this list as they enter a new customer/client into their database.

The Zip+4 product does not have data for the given zip+4 or even the 5-digit zip code.  Rather it appends the data for the block group in which the zip+4 is found.  Thus if one hundred zip+4s are all located within the same block group then the same data would be appended for each.  The 2013 Zip+4 contains the US Census Bureau’s latest TIGER/Line® Shapefiles and the US Post Office’s National Zip+4 data set. The Zip+4 DVD uses improved geocoding technology developed by GeoLytics and includes over 35 million zip+4 records.

The Zip+4 is a stand-alone product that offers accurate, high-speed geocoding and an affordable price.  For more information on GeoLytics’ Zip+4 2013, go to: http://www.geolytics.com/USCensus,Zip4,Products.asp

Site Reporting for Entire Databases of Addresses or Lat/Longs from GeoLytics

With GeoLytics' software, you can run your entire address file through a site reporting system.  The output is a table of the demographics for up to three given radii around each location.  For example, you could run a 1, 3 and 5 mile radius report for each of your store locations. We can run radii for as small or as large a circle as you wish.  Often folks will select 1, 2, 3 or 5, 10, 15 but in fact we could do any distance. And our newest version of the Site Report will now allow you to run these radius reports from latitude / longitude coordinates instead of using a full street address.  So now you can choose -- either addresses or lat/long coordinates.  Whichever you have, we can run the report.

Our stand-alone Site Report 2012 provides a comprehensive report of demographic data for 2010, and projections for 2017 in 3 rings around your target address. Similarly, the batch mode version can do this for your entire database in a single pass.  For example if you have 50 stores or even 50,000 you could run it through the batch site reporter and you can set the distance for each radius in the report.

The variable groups included in the Site Report are: Persons, Race/Hispanic, Households, Families, Employment, Education, Veterans, Income, and Housing. The 2010 demographic data on Site Report 2011 are based on the official 2010 Summary File 1 (SF1) data from the US Census Bureau as well as their 2006-2010 American Community Survey (ACS).  The SF1 is the 100% count and is therefore considered more accurate but it does not include important demographics like income, educational attainment, employment, etc so that is pulled from the ACS.  The ACS is also official US Census Bureau data but is collected over 5 years (2006 - 2010) so it is not strictly speaking 2010 data. The 2017 projections are from GeoLytics’ proprietary estimates and projections.

For a complete list of all of the variables, go to: http://www.geolytics.com/USCensus,SiteCD,Data,Variables,Products.asp

To see a sample report of the SINGLE site report, go to: http://www.geolytics.com/USCensus,SiteCD,Data,Sample-Report,Products.asp

We also offer the Site Report 2012 on disk or online if you prefer to run the addresses yourself one at a time.
