Demographic Data Layers Missing after Upgrade

Issue

After upgrading to Tableau 2019.2, some demographic data layers are missing, and some data layers use 2016 census data rather than 2018 projections.

Environment

  • Tableau Desktop 2019.2
  • Tableau Server 2019.2 
  • Tableau Online 

Resolution

This behavior is known and expected. The data layers are sourced directly from U.S. Census ACS, where they previously were sourced from Nielsen Claritas.

Cause

Tableau 2019.2 uses U.S. Census ACS as its demographic data provider and is unable to offer replacements for certain demographic data. Previous version of Tableau used Nielsen Claritas, which included estimated data and 5-year projections derived from baseline U.S Census Data. In Tableau 2019.2, it was decided to completely replace the demographic data source from Nielsen Claritas to the current U.S. Census American Community Survey (ACS )Data.
 
Background
The Nielsen Claritas demographic data included estimated data and 5-year projections (using their own proprietary methodology) derived from baseline U.S Census Data. In short, the Nielsen data for 2018 was estimated/calculated data based on older datasets. For multiple reasons,Tableau decided to make the change to directly using the U.S. Census ACS data, which does not include 5-year projected data. The ACS uses yearly surveys as sample data to infer updates to the baseline decennial census (2010).  When building the 2019.2 version of Tableau, the latest available dataset from the census was for 2016. The latest data that has been released by the Census Bureau is for 2017, and Tableau is in the process of updating to this latest datasets.

Additional Information

The data layers no longer present in Tableau as of version 2019.2 are: 
  • Population growth projections
  • Household growth projections
  • Effective buying income (median) 
  • Housing unit growth projection
  • Year Structure Built (median) 
  • Length of residence (average in years)
