Census Block Group data from the latest American Community Survey (2014-2018 5-Year Estimate)?

How do I find Census Block Group data from the latest American Community Survey (2014-2018 ACS 5-Year Estimate)?

• I get errors when trying to download the individual tables from the Census Bureau
• I can only find information at the Census Tract level on Esri Living Atlas. For Median Household Income, for example, at the smallest geography available is at the tract level: 
• REST API: https://services.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/ACS_Median_Income_by_Race_and_Age_Selp_Emp_Boundaries/… 
• Current Vintage: 2014-2018
  ACS Table(s): B19013B, B19013C, B19013D, B19013E, B19013F, B19013G, B19013H, B19013I, B19049, B19053

Hi Veronica, 

You can pull the block group data from the Census' API for ACS data, although you'll have to go county by county.  Here's an example to get basic median household income from table B19049 for Antagua County, AL (fips: 01001):

https://api.census.gov/data/2018/acs/acs5?get=NAME,group(B19049)&for=block%20group:*&in=county:001&in=state:01

Essentially the request is for all of table B19049, blockgroup is wildcard, or all block groups, denoted by (*), within the county of interest.

For more info, you can look at the Census Data API User Guide: https://www.census.gov/content/dam/Census/data/developers/api-user-guide/api-guide.pdf
