It seems that my API calls for tract-level data are not working for the 2017 5 year data, yet the same call for the 2016 5-year tract-level data work! I am successfully getting data for my calls for state and county for 2017 5 year data, just having a problem with tract-level. Here's what I'm doing to get median age data for all tracts in AL, for example:
https://api.census.gov/data/2017/acs/acs5?get=NAME,B01002_001E,B01002_001M,B01002_002E,B01002_002M,B01002_003E,B01002_003M&for=tract:*&in=state:01
error: unknown/unsupported geography hierarchy
https://api.census.gov/data/2016/acs/acs5?get=NAME,B01002_001E,B01002_001M,B01002_002E,B01002_002M,B01002_003E,B01002_003M&for=tract:*&in=state:01
gets data successfully
What's going on?
