New ACS 2015 1-Year Demographic-Economic Data

.. essential data to assess where we are, how things have changed and how things might change in the future down to the sub-neighborhood level. The American Community Survey (ACS) is a nationwide survey designed to provide annually updated demographic-economic data for national and sub-national geography. ACS provides a wide range of important data about people and housing for every community across the nation. The results are used by everyone from planners to retailers to homebuilders and issue stakeholders like you. ACS is a primary source of local data for most of the 40 topics it covers, such as income, education, occupation, language and housing. ProximityOne uses ACS to develop current estimates on these topics and 5-year projections. This section is focused on ACS 2015 data access, integration and use and is progressively updated.

New ACS 2015 1-year estimates are available as of September 15, 2016.

Importance of ACS: Assessing Demographic-Economic Change
Oil prices plummeted in late 2014. How has this affected people and households in areas hardest hit? Find out for wide-ranging geographies using the ACS 2015 1-year estimates. Compare to ACS 2014 1-year estimates. Use the ACS 2016 1-year estimates (September 2017) to see how the impact has continued. Demographic-economic conditions change for many reasons; oil price changes are just one.

Keep informed about ACS developments and related tools and applications:
• Updates are sent to ProximityOne User Group members (join here).
… access special extract files and GIS projects available to members.
• ACS updates and applications are covered in the Data Analytics Blog.
• ACS data access, integration & use … join us in a Data Analytics Lab session.

In the weeks ahead, the following ProximityOne information resources will be updated with new ACS 2015 1-year data:
U.S.-State-Metro Interactive Tables
• Demographic component section of Metro Situation & Outlook Reports .. example for Dallas metro
• Housing characteristics component section of Metro Situation & Outlook Reports .. example for Dallas metro
Demographic-Economic Trend Profiles
• Special study reports.

Join me in a Data Analytics Lab session to discuss more details about accessing and using wide-ranging demographic-economic data and data analytics. Learn more about using these data for areas and applications of interest.

Mapping Block Group Data

.. demographic-economic patterns and characteristics can often be “masked” when using larger geographic areas such as counties and metros. Using data for small area geography such as census tracts and block groups can help identify clusters and areas of interest. Now, demographic-economic data for block groups (217,000 areas averaging 1,200 population covering the U.S. wall-to-wall) are tabulated annually from the American Community Survey (ACS). There are hundreds of subject matter items updated annually. Without specialized tools, it is very difficult to navigate through the maze of small area data that are available and make effective use of these data for analysis and decision-making.

Use the combination of API tools and GIS tools described in this Web section to visually and geospatially analyze demographic-economic characteristics of block groups. Covering the U.S. wall-to-wall and averaging 1,200 population, block groups are the smallest geographic tabulation area for data from the American Community Survey (ACS 5-year estimates). Block group (BG) data are also available from Census 2010 Summary File 1 (SF1) for the same block group area geography.

Install Tools
There are two software tools involved to create maps such as the one above for any county in the U.S. using block group level data for multiple years, flexibly choosing among more than a thousand subject matter items. Steps to use two tools are described in this Web section. You can perform these operations for any area in the U.S. and use the resulting maps and data in any manner.
• Demographic-Economic Data Extraction (DEDE) API tool
CV XE GIS software
See the corresponding Web sections above to install the Windows-based software. There is no fee to use these tools to perform operations described here. There are no block group subject matter datasets to download. The steps to use these tools are summarized here.

Get Help Using these Resources
The flexibility and breadth of data selection options afforded by access to thousands of subject matter items from multiple statistical programs requires several steps to use the data in GIS applications. Join us in a Data Analytics Lab session for additional assistance. We can go through/discuss any aspect of steps summarized here. There is no fee for the Data Analytics sessions.
